Simple Question
Posted on: 31/12/2003 18:16:00

Need what seem like a simple bit of information, yet is hard to find. Does anybody know what a "group" of newly hatched fish are called? For instance a group of young lions is called a "pride", a group of birds is called a "flock". I seem to remember that a group of young fish was called a "fry", but I'm not sure.

29G many questions for new tank/fish
Posted on: 19/12/2003 06:57:00

Set up tank on 12-12-03 so it's still in the cycle stage. Petshop said that I could add 5 fish so 3 redeyes & 2 platys. At the beginning the 1 of the redeyes was a nipper and swam around. A few days later, he(?) began cowering in a corner behind a plant; I wonder why? Also, the tetras won't come to the top unless the light is off. The platys swim all over the place and seem quite happy other than I noticed that they like to rub against the plastic part of the heater and a clay pot; so could that be ICH? If it could be, how should I treat them while cycling the tank? BTW, I don't have another tank. I was told to keep the Rena Cal Top Light Excel heater at 80. The thermometer shows to be 82. I wonder which is right? I'm feeding them tropical flakes every other day. Also, should I keep the water level at the top of the tank even though it's cycling? I prefer to get 2nd opinions instead of relying on this petshop because I don't think the salesgirls are knowlegable enough. Thanks so much for replies/advice.

Evermannella melanoderma / indica
Posted on: 11/12/2003 04:41:00

I recently noticed a mistake in one of the species profiles, The species profile for Evermannella indica Brauer, 1906 states that it is replaced by E. melanoderma (Parr 1928) in the Atlantic Ocean, however you still list E. balbo atlanticus Borodin, 1931 as a synonym of E. indica Brauer, 1906, this synonym (E. balbo atlanticus Borodin, 1931) however was described from a specimen collected in the Sargasso Sea in 1929 so technically E. balbo atlanticus Borodin, 1931 should be a synonym of E. melanoderma (Parr, 1928) and not a synonym of E. indica Brauer, 1906.

Fish identification
Posted on: 10/12/2003 08:01:00

I have a video taken around mariculture cages, in Greece and I want to identify the fish I see. I am very confused with the smal fish you can see in the attached pictures. My final guess is that they are juvenile Sardina pilchardus, because I see a dark stripe along the middle of the side of their body. Could it be something else? How can I distinguish those fish from Boops boops?

Ornamental fishery
Posted on: 2/12/2003 03:38:00

Dear Sirs/Madam Iam working with the Indian Council of Agricultural Research, India in the discipline of fisheries. I am working in the North Eastern part of the country where the diversity of fish fauna is amazing and most of them having ornamental potential. I have been working in the field of ornamental fisheries for the past two years. I wish to have an international project to continue my research in the same field focussing mainly on the molecular characterization of fish species and breeding of the potential ones. Therefore, I would appreciate if you can kindly let me know some international funding agencies who would sponsor such research programmes. Thanks VINOD,K.

African Snappers
Posted on: 29/11/2003 18:04:00

Hi there, I'm constantly hearing about two big Snappers available in the western african waters, their volgar names are Carpe Rouge (Red carp) and Diabar and people there swear that is a different fish. My amatorial investigation suggests that there's one major Snapper which is the Lutjuanus agennes and a second one that is the Lutjuanus goreensis. Unfortunately the latter doesn't seem to reach the size that those Snappers reach, the Carpe Rouge and the Diabar are said to grow in excess of 50 kilos. I have seen pictures of both fish, and I have caught myself in Gabon fish that the locals would distinguish between the two species but my feeling is that is only the color of the fish that is different, not the fish itself, being the goreensis a smaller critter. Anybody has some imput on this one ? Thanks in advance ciao Nicola

help: class Pisces and acanthoptergii
Posted on: 13/11/2003 18:39:00

I am a postgraduate student studying in information and knowledge management. Due to a recent assignment of taxonomy , I read a lot of books about fish. There is a question that I read one book named "living fishes of the world", it says bony fishes belong to class Pisces. So tuna and swordfish belong to class Pisces. While another book named "fishes of the world" says tuna and swordfish belong to class actinopterygii. As a layman, I am really confused about it now. I am wondering if there is a correct answer? I just want to know which class tuna and swordfish belong to. Could you mind helping me anwser this question? Thanks a lot

unidentified fish
Posted on: 15/10/2003 18:48:00

I have been fishing the suoth Florida waters for the past twenty-five years. During a cold water upwelling this summer, I caught an unusual fish in the St. Lusie Inlet. The fish was aprox. 12 inches in length. It's body was smooth skinned. It's skin was light tan with white spots aprox. 1/16 in. in diamater. The peck fins were like those of a sea robin, but colored in distinct black and white stripes running lengthwise from the base of the fin to the outside edge. It's tail was similarly marked and smoothly rounded.The eyes of the fish were aprox.1/8 inch in diameter and chartreuse in color. The mouth was upslung with tiny teeth. The body was shaped somewhat like a puffer. I assume this fish was some type of bottom fish. If you could help me identify this fish, I would appreciate it.

Unidentified Fish - Rasbora?
Posted on: 13/10/2003 00:31:00

Could someone please help me identify a fish that I recently purchased from a local pet-store. I will try to post a picture as soon as i get the prints, but here's a description anyway. Now, the store-keeper identified it as a Scissortail Rasbora (Rasbora trilineata), and it does seem that it is a variant of one, as the markings on the tail are identical to that of the R. trilineata. The most distinct feature of the fish is an intense fiery red stripe that runs from the mouth to the middle of the body (terminating a little before the dorsal fin), running over the top portion of the eyes as well. A distinct black stripe runs along the lateral line and is topped by the red stripe described above. The dorsal fin is also red, with the color more concentrated towards the base of the fin. The body shape is very streamlined - the typical torpedo shape and the black and yellow tail markings being reminiscent of the R. trilineata. The body colour itself, though, is not as pale as the trilineata - and is more of a pale yellow (a good analogy would be the colour of the scales of Tiger Barbs). The barbels are visible as thin whiskers. These fish were between 2-2.5"(SL), 2.5-3"(TL) when I purchased them (just a week ago) and the maximum size i have seen before would be around 3.5"(TL). I do believe they will outgrow a length comfortable for my 48" tank though, which is true for Scissortail Rasboras. These are bold fish that spend a lot of time swimming gracefully in the middle levels, and they like to swim across the length of the tank. Must I add that this is one of the most beautiful school-fish I have ever seen (although I did have to pay a beautiful price for them as well) and it makes me sad not to be able to find any info on the care of the fish (can't run a search without any name), or when somebody asks its name - which tends to happen a lot, as my four "Comet" Scissortail Rasboras (As I have decided to name them for the time being!) - are currently the highlight of my 60 gallon planted tank. To help gauge the attention these fish are gaining inspite of its tank-mates... my tank also includes 8 Neon Tetras, a shoal of 10 juvenile Tiger Barbs, a pair each of Praecox Rainbows, Serpae Tetras, Penguin Tetras, Honey Gouramis, Black Mollies, 3 Black Phantom Tetras and a lone Kuhli Loach. If somebody has a clue as to which species this is, info will be appreciated.

Beta splendens female guards nest
Posted on: 12/10/2003 11:05:00

I wonder, if anybody has observed the same phenomena in the siamese fighting fish, as I did today. I had put a young, small virgin female beta splendens in a small breeding cage in a fish tank and set a second, large female that was through with breeding into the same tank. the two females could see each other through the net of the cage, but seemed to take little noticed of eachother. the young female in the cage though started to build a small nest of bubbles and laid eggs, which it now gards and keeps like a male breeding beta. I am surprised. None of my books which I consulted, has anything like that explained or mentioned. Has anybody any idea, if that is a common behavioural pattern? please let me know. thanks! Peter

Hello all. A friend on mine is keeping a frogfish (Antennarius sp.) and is worried that the fish never eats (he never saw it eating!). He's worried that the fish will starve. Is there any special food items he should give to the fish? thanx

What's wrong with my fish?
Posted on: 28/9/2003 05:07:00

Please help! I've had my betta for about 3 years now, and he's been acting a little strange lately. He stays on the bottom of the tank a lot, and seems to have trouble trying to swim to the top. He tries to go to the top to feed, so he's still interested in food, but it just seems like he hasn't got the strength to get and stay at the top. Is there something wrong with him?

Currently have a pair of these damsels spawning I have examined the eggs at day 3 and they show know eye pigmentation or mouth development. Does anyone know what the igestation period is for this species are they similar to angel fish hatching with no eyes or mouth and developing it later? There apparent small size will also make it difficult to offer a suitable first food item. Egg size 1.2mm x 0.75mm Rotifers i think will be to large and may have to look at cilates or copepod nauplii? any suggestions?

Red Capped Oranda
Posted on: 6/9/2003 21:43:00

Hi I need some help! My Red Capped Oranda named Bubbles is sick but I dont know what is wrong.. We've only had them 2 weeks my other fish is a telecope eyed, today I noticed that part of Bubbles scales are missing, we did have some chinese algae eaters in there that were attacking the fish, we've since then taken out the alage eaters, but now Bubbles sits on the bottom of the tank not really moving, and he hasn't eaten. It's only been 1 day but I am worried he might have Flukes or something else.. The lady at the pet store didnt seem to be too worried about diseases she said Bubbles was most likely stressed and just needed some time to relax, but that I should do a water change which I did... Please someone tell me what is wrong with my Bubbles... Also Googles the other fish seems to be fine... Please send e-mails to [email protected]

Hello, my name is Eduardo Quevedo, I studied Veterinary Medicine and I go to you because I need information on the product Tricaine Methanesulfonate(ms-222), that it is soluble in water therefore is very good for the sedation and even the surgery of fish. I am preparing my thesis that is based on the investigation of the product to be used in reef fish, because most of the charts made until the moment are investigations made in fish of fresh water. The idea is to work in Xcaret Park located in Playa del Carmen, Mexico. With the Dr. Juan José Bolaños that works for 9 years in the aquarium, where it is necessary to have some parameter to be able to occupy the product without danger, therefore I would like to know if you manage this information and what class of samples have they taken to be able to measure the concentration of the product in the fish or times of induccion, recovery,etc.?, if you don't have this information, to who can I ask?, I thank your time and I wait your answer. I really like to work in investigation and this is my oportunity to start , maybe this research it´s already done , but I don´t know, that´s why I asking you and I would like to be in contact with you if you have the time, thank´s.

A couple of weeks ago I was at the Santa Cruz (California) harbor while a commercial salmon fisherman was unloading his catch. He also had caught a strange fish by accident, which had been tangled up in the kelp and his line. He showed us bystanders the fish, which was about 150-180 cm long, and appeared to weigh about 20 kg (based on the fisherman's comments). The color was white, with some pink. The eyes were solid black, and about 1 cm diameter. The closest similar fish I could find on this web site is the Red cusk-eel. I didn't get any pictures, unfortunately. Any ideas?

Dear Fish Base & forum members here, I am from Singapore and I am conducting a research on Anabas testudineus (aka 'Ikan Betoks'), a type of climbling gouramies that can survive out of water for hours. I have some questions for the experts here: i) Are Anabas testudineus an endangered species & allowed to be trade internationally? ii) Are there any Breeding/Spawning information on Anabas testudineus in this website? >> Otherwise, can a kind soul here point to me a link that have the spawning details of Anabas testudineus?

Giant Tarpon and Snook in fresh water
Posted on: 31/7/2003 15:02:00

Fishing report # 45: San Juan River Nicaragua For an easier reading Full report , Newsletter and Pictures at : Long time since I wrote a fishing report and I am getting E mail asking what’s hapening ... We are well and alive still fishing sucessfully with Guests our San Juan River . Sorry for the missing reports but I have reallly been super busy with the improvement of the internet site at and building of the new Guests house on my land in front of San Carlos...on shore of Lake Nicaragua... a lot of work for all of us...on No Fishing days everybody fishing guides included become carpenter... and I move from my computer to the wood workshop... Obviously the international events: war in Irak and SAR Virus had negative effect on my booking in all spring 2003 but even in such situation we did have many guests coming and “as usual” all of them had tarpon : Terry from Mineapolis.. , Julie and Fabien from France, Etienne and Bertrand from France Bill , Randy, Irvine, from Seattle and Alaska., Mike and lindy from Florida., Janos, Camilla from Sweden Bob and Family from New Mexico , Jeff and Kelly from Seattle.. For most of these guests this trip with us was not the first one some where at trip #4 on San Juan river... there is always something new to discover in our Fishing Adventures... As predicted ( see Report #44 ) from June we observe in San Juan River a tremendous quantity of fish ( Tarpon size 20lb to more than 250lb ) all around, going up and down river. Remarcable also , some changes concerning the feeding area... “Activity Zone” I like to talk a bit of this idea of “ feeding area or Activity Zone” as I consider it is very important for the quality of our fishing . I do not want to say than this is true for all tarpon fishing all over the world.. but what I know is than at least this is true concerning the 120 miles of our San Juan river river and also in Cano Negro and Rio Frio in Costa Rica than I also know very well... Since 4 years we are Sport Fishing there..., we observe than there are diferent behaviour of fish according to where they are.. Exist places where you can see thousand of tarpon “Rolling” “breathing” slowly generally by two or three very close from each other in a behaviour we figure related to reproduction ... There we are ... When you see this DO NOT WASTE YOUR TIME...unless you want to enjoy super frustration... it is almost impossible to have these fish bite... trust me we tried... whatever the hour, the moon , the lure, the fly , the live bait etc etc this is what we called a DON’T LOSE YOUR TIME AREA it can be on a mile of river or 20 there may be 1000 tarpon or ten thousands... in variable sizes..( Note , In such a zone your only chance ..’’ very very small” is to have one of the tarpon being Upset by a lure..he will then not grab it but Push it then you may have a chance...and a fin hooking!! ) For me and my guides there is no doubt than this ballet is related to reproduction.. and in our San Juan River this may happen at any months in the year.. in these area tarpon do not feed do not bite even if baita are abundant.. .. but then at the same time 10 miles ahead or down river they will ... a totally diferent behaviour it will not take long before they take this same fly or lure you could have cast unsuccessfully for a half day in other place.. Since 4 years we almost daily fish the river and we have been lucky inoff to locate the Activity area ( Bitting in a specifiv one will be good for a month or three , location of these place also vary according to Water level and time of the year...) Remark On writing that ( Specifically what concern reproduction ) I may give a problem at Marine Biologist... as it is said write and known than tarpon do not reproduce in Fresh water..??? Our Fishing grounds are Fresh water at 120 miles from sea ...So? Well I invite all scientifics interested to be in touch with me, as I would like to start a tagging program etc etc... Please All opinion, comments from Fellow Fishermen are welcome... I forgot.. I have report of Local professional Fishermen who said they caught very small tarpon...and what about this baby tarpon 15 cm. ( 6 inches ) . caught acidentally by the back in Solentiname by one of our Guest from Texas in January 2002? Back to Sport Fishing.. In my opinion success in Tarpon fishing in San Juan River is of course made of using the right type of Lures , ( or flies ) with the good colour according to light and water is also a matter of moon or hours and x Factors known from my guides.( they are all Born here are for example fascinate by behaviour of Aigrets on river bank one of their indicators..etc etc..) all these are the basics for a sucessfull fishing .but In my opinion there is something more: being able to corectly clasified the Zones of the river according to signal given by tarpon behaviour.. Size of fish we catch and release in San Juan River is generally between 80lb to 150 lb ( We also observed the presence of much smaller fish ..20, 30lb but not in big quantities.. ) then we have the big one from 150lb till 200lb and then the monsters as this 105 kg fish caught in June 2003 by Irvine from Seatle..... Exceptionaly (and unfortunately.) . we weighed this fish as it did swallow the lures , and was hold inside by the Gills and bleading dramatic circumstances.. ..This mean no chance to survive reason why we know the Exact weight ... I know this will sound unbeliveable to many readers but we already had bigger fish on in several ocasion but could not take them to the boat.. Remark ( For the real “Tarpon Aficinados” ) these Giants do not jump. only shake with extreme violence , a third or half of the body out of the water .. Anyway Concerning this Irvine’s Tarpon I have been told than this is the bigest tarpon ever caught in Central America.. and may be in all americas excepting this monster of 283 lb caught in Venezuela.. ( March 1956 this is the actual IGFA all tackle world record duce with another fish caught in then peacefull Sierra Leone. 1991. ) Another event I like to mention concerning this spring is than we have 5 new kids entering our Junior tarpon club... Open to boys and girl under 12 years old.. each of them caught at least one tarpon between 100lb and 150lb, congratulation to Alex 9 years old , Alain 8 years old ( These two are my sons.. in begining of July they caught several tarpon each...) then a very special mention for Sarah 10 years old from new Mexico who caught a 150lb ...( these weight are estimation as all these fish has been released..) . ... Fishing will be great in the coming months as we have a year with Chayul... ( small insects, flies who do not bite but are many so many..) . baits feed on them....then tarpon feed on bait...Well you know.. ) when we have such a year we know than fishing is going to be great til ar least the end of February next year.. Matter of Activity Zone Will start soon to work on my planning it’s time to be in touch with me for the coming months but also for the High season from October till March.. Philippe Tisseaux.

Hello, my name is Eduardo Quevedo, I studied Veterinary Medicine and I go to you because I need information on the product Tricaine Methanesulfonate(ms-222), that it is soluble in water therefore is very good for the sedation and even the surgery of fish. I am preparing my thesis that is based on the investigation of the product to be used in reef fish, because most of the charts made until the moment are investigations made in fish of fresh water. The idea is to work in Xcaret Park located in Playa del Carmen, Mexico. With the Dr. Juan José Bolaños that works for 9 years in the aquarium, where it is necessary to have some parameter to be able to occupy the product without danger, therefore I would like to know if you manage this information and what class of samples have they taken to be able to measure the concentration of the product in the fish or times of induccion, recovery,etc.?, if you don't have this information, to who can I ask?, I thank your time and I wait your answer. I really like to work in investigation and this is my oportunity to start , maybe this research it´s already done , but I don´t know, that´s why I asking you and I would like to be in contact with you if you have the time, thank´s.

Adult Anguilla Migration
Posted on: 18/7/2003 03:55:00

I am currently researching the life cycles of the freshwater eels, Anguilla anguilla and Anguilla rostrata. I would like to substantiate or repudiate the claims that mature eels travel overland from inland lakes and ponds in order to find their way back to the sea and that elvers adopt a similar mode in order to initially find freshwater. I would be grateful for your assistance. I have been fortunate on one occasion to witness what may have been a mass invasion of elvers overland. The elvers appeared to be making their way up a wet boggy field during a rain storm. The event took place in North Wales, UK adjacent to a storm beach and well away from a river or any other source of fresh water. I have no idea where they were heading or indeed whether or not any of them actually made it to freshwater. It seemed clear to me that they must have simply left the sea over the stoney beach just a few hundred metres away. Even though I searched the shoreline, I did not see any elvers there, but hundreds of them were in the wet grass, squirming their way up to the top of a gentle incline. It had rained persistently for some days and the field was waterlogged. Elvers inhabited every puddle which had formed in the depressions caused by cattle or tractor tracks. It seemed to me that they must have all come ashore together. It was possible I suppose, that the elvers could have been cast up onto the beach during high tide by a particularly powerful wave, however, on the day in question, the sea was quite calm. Unfortunately I have no recollection of the wind strength and sea state preceding this event. The chances of any of those elvers reaching freshwater somewhere, is on first inspection, remote. It is understood that elvers usually enter freshwater via an estuary and then along a river, into a stream or ditch and finally into a pond or lake via an underground spring, (or through loose gravel or shale and on into the lake). It is certain that many inland lakes and ponds do not have any visible connecting water source or overflow, but they do hold a quantity of mature eels, and of course, they had to arrive there somehow. I therefore accept that elvers can and do find their way these inland freshwater habitats but I am not entirely convinced that they could travel very far overland without being spotted and eaten by bird or predatory mammal and I am not convinced that mature eels could exit a pond or lake in the same way due to thier bulk. A mature eel is of a greater size compared to an elver. Like elvers, they could use overflow ditches and drains before reaching major rivers, but for those eels that would have to take the overland trail before reaching such a ditch, one would expect them to be fairly frequently observed! I have spent a great deal of time in and around the countryside yet I have never seen an adult eel outside of its natural environment clearly migrating towards a watercourse. Furthermore, I have never met anyone who claims to have witnessed such an event either. If an adult eel is placed on wet grass, it is instantly apparent that its form of locomotion is not particularly efficient. In order to move at all, the eel has to perform energy sapping gyrations that would attract the eyes and ears of any predator. Slime left by the eel would provide a simple clue for any predator to find it. Would predators such as badgers, foxes and otters know of the times when eels can be expected. Do eels form part of their diets during such times? Surely any large eels making an overland journey across fallen rustling autumn leaves are likely to be spotted somewhere along the route and be widely reported? I do know that when the mature eels start to migrate, they do so en masse so to speak, and many of our larger river courses trap a vast number for the commercial markets at this time. I also accept that these eels have joined forces with eels from many other waters, and not all of the eels from one particular water will leave it at the same time. It is also held that migrating eels do not feed since their digestive systems stop functioning. Is this so? If it is so, why then are silver eels caught by fishermen in huge numbers from the sea, especially during spring. (Not the accepted migration season) Do some eels remain in the sea all their lives or are these actually migrating eels which are indeed feeding? I would be extremely grateful for your comments and any scientific evidence that you can point me towards regarding my queries. Yours sincerely, Kevin Thornton

On the part of the fishbase web site there is a number of pages showing pics of fish, as there are so many I cant get through them all in one go so when i go back to continue where I left off i have to click the 'next page' link, this is irritating when i want to look at some of the pics that are not near the beggining, I.E if I want to go to look at the pics on page 30 then it seems to me i'll have to click the 'next page' link 30 times, as there are so many pics on each page it takes a while to complet. could you do it so if someone wants to go to e.g page 20 they can just click 'page 20 link'.

Mini monster fish
Posted on: 2/7/2003 10:16:00

I caught a fish off the rocks in spain which looked like a small monster! It had a very spiny dorsal fin and also large front fins which were spiny (kept hands well away from those!! Its eyes were on top of its head looking forward (as oppose to on each side)and its colour was a sort of very dark red/brown and sort of white. It's mouth was very big, almost as wide and high as the fish. The fish was wide and looked as though it was more accustomed to naturally lie on the sea bed and wait for it's prey I suspect. It's skin was very bumpy and basically looked more like a little moster rather than a fish! I didn't have my camera (darn!). Anyone have any ideas what it was? as I would love to know what it was. Thank you in advance.

Ascending walleye
Posted on: 2/7/2003 08:04:00

Iam a fresh water fisherman mostly catching smallmouth bass and walleye in the eastern basin of lake erie.I have wondered for years just how long it would take a walleye that was at a depth of sixty feet during the day to come to the shallows to feed at night?My thought is that with the closed off gass blader this would have limits on just how fast the fish could make this transistion.Under water sounds have always been an interest to me and i was wondering if the fish we are catching makes any sounds that we might hear.Thankyou for all the interesting fish information you are teaching me now that i am in my mid seventies,never to old to learn. thankyou russ johnson

It has what appears to be tiny veins in this white bulge. Arond this bubble, there is a crease in his side and just a deformed appearance. I am wondering if I may have smashed fish while I was removing rocks,or does this sound like a bacteria , parasite or ??? Thanks for any help I receive!

small question about the collection databases
Posted on: 27/6/2003 08:29:00

I have been using your "fish collection search" page very often for quite a long time now, but there is one thing that can become quite annoying, the limit of records per page is always set to 1000, which can really cause problems if it returns alot of records, because such gigantic lists will really take long time to load. I think it would be a nice idea if this limit could be turned into a input field, where people could manipulate it like other query criteria. As a second note, in some cases the server will timeout the request if there are over ~3000 records in total.

Pacu - Piaractus brachypomus
Posted on: 25/6/2003 22:32:00

Dear all There is an enviromental concern about the species Piaractus brachypomus in Viet nam. Millions of juveniles of this species have been imported to North Viet nam (via China)for aquaculture. Afterwards it also has been imported to South VietNam. This species has been recorded to attack other fish species in fish farms and even eating dead mouse or dead dog. In some areas around Dong Nai river,which is a flooded areas, also many farms raise this species. I would be very happy to receive recommendations on this species if it escapes to natural habitat. Can it establish the population in the wild? Can it cause adverse effects on native species?

Can anyone help with an ID for this jawfish. Found in 25m on flat sand/gravel bottom off Mabul, Sabah, NE Borneo. Its about 2cms long and the only one in the area, the only one I've ever seen. It was displaying constantly: first it would vibrate its head against the bottom, then jump up whilst opening its mouth and waving its fins. Not visible in the photo is a black spot outlined in electric blue at the front end of its dorsal fin. Any ideas??? Matt

Cottidae of southern California waters
Posted on: 26/5/2003 07:04:00

Are there any experts out there on the Cottidae of the eastern Pacific? In particular, I am referring to the Southern California Bight. I have an identification problem regarding a sculpin I am seeing in the mouth of the Redondo Submarine Canyon. The sculpin in question is: •about 10 cm in length •typically ceam colored with approximately four dark saddles •has small cirri on the head and prominent cirri along the lateral line •has a conspicous dark spott on the upper leading edge of the foredorsal •has bars on the soft dorsal and caudal fins I am seeing it in depths form approximately 12 to 24m over a sandy/silty bottom with drift algae. Visually, it appears to most closely match the northern sculpin, Icelinus borealis. However, as I am seeing it in southern California, it would be way out of the range of I.borealis. Any help in sovling this problem would be greatly appreciated, and I thank you for your time.

Survival of the little ones!
Posted on: 7/4/2003 07:37:00

Being new to the aquarium hobby, I "fell" for the charms of a wonderful Pictus Catfish. However, not realising this fish is a predator, (would have been nice if the shop assistant had told me!) I introduced several Glowlight and Neon Tetras. Each morning I would awake to debris that is best left undescribed!! I did not want to get rid of the Pictus, and I really wanted to have the little ones too, so I simply buy the biggest Glowlights or Neons at the shop, (this is usually enough to enable survival), but if I think some are too small, for the first few days I just leave the light on. Pictus only seems to "kill" with the light off!

Mysterious fish species
Posted on: 25/3/2003 08:12:00

I have observed this small fish many times while walking Pacific beaches in Costa Rica. It favors rocky areas in the intertidal zone and hangs around blowholes. It's small (2-5 inches) and climbs around on the rocks, using its pectoral fins for locomotion. It has no dorsal fin. This fish can stay out of the water for quite a while. When out of the water, it seems to be grazing on the rocks. The body shape is long and lizard-like. The fish swims nicesly in the water, but I've also seen it skip along the top of the water by using its tail and pectoral fins. I've never seen anything else remotely like it and wonder if anyone has any info. I'd love to know what kind of critter it really is.

plecostomus diagnositics for health condition
Posted on: 24/3/2003 20:54:00

Hello, Can anyone help me understand what is wrong with my plecostomus. He or she is 1 foot long and been with me for over 2 years. He or she just won't eat. This has been going on for weeks now, and I can't imagine he or she can survive much longer. It has been several weeks since I had to move him or her to a new aquarium because the old was became too small, and his/her nocturnal rampages was disrupting the other fish in the aquarium. Since his companions aquired a bactera infection which I have treating with antiobiotics, I wonder if he/she also got infected prior to move. so I have also been treating his/her tank with antibiotics but still will not eat. Perhaps the only other descriptive feature / incident is that the otherwise dark grey body color, with beautiful spots and stripes, does seem to have patches of light color, like white-hazy,, but it seems natural, not like fungus. Yet I guess it could be something.. any ideas?? Please, I love this fish!!! Thanks LInda

Atlantic Needlefish
Posted on: 17/3/2003 17:35:00

I have a question as to the range of the Atlantic Needlefish. I have some friends who have caught what they believe to be this species in the Tennessee River near Huntsville AL. They are well versed on the fishes of the area and though not Zoologists are well educated. They say that they have seen and caught many of this species and have sited to me some sources that show some of these fish to be found in these waters. Most of the sources that I have seen show it to be a marine species and that it can range into coastal rivers but Northern Alabama is a far cry from this. They say that they see them frequently near the steam plants in the winter. Is there a possibility that because of the warm water outflow of these plants that species are able to range into these areas? Is there a possibility that they are able to mate in fresh water? It sounds like a stretch to me but is there anyone who would know the answers to these questions and are there other species that have had similar changes in range? I could understand a population moving up the rivers but to sustain the population it must reproduce. Is anyone working on these questions?

Fishbase server
Posted on: 8/2/2003 15:29:00

The server for this site is terrible. Everytime I try to access, .de, or .fr half the time it says "This page cannot be displayed" or "Website not responding" or just loads for like 15 minutes. When it does work it can take like 10 minutes to load a species summary for even a obscure fish with little info. Many times it works for a few species then goes back to "This page cannot be displayed". I then have to back out. This is very discouraging for a good site like this with so much info to have such a crappy server. I have a cable modem here so its not that. Thanks for any info. Ray

Tarpon Snook fishing nicaragua
Posted on: 7/2/2003 19:01:00

Fishing report # 43 28th of January 2003 Report from Philippe Tisseaux, Tarpon snook fishing on San Juan River Nicaragua... The complete report and pictures for the month of January 2003 and these trip are at Also If you are interested in tarpon I sugest a look at my new Tarpon Picture Galery located at: REPORT FOR THE MONTH OF JANUARY . Fair weather sunny sometime hot with eventual short rain..some days with strong wind, several cold front during the months witch interfered on fishing.. We have been very busy fishing our jungle San Juan River during all this month of January , with groups coming from France, Usa, canada... Fishing has perhaps been a bit slowler than last year ( Cold Front ?) ... fish have been super present ( a lot of them but a bit lasy ) they have been bitting in the morning or the evening , not both as usual ..For Example we had 4 or 5 tarpon on between 5.30 am and 9 am ..then only 2 or 3 tarpon on during the rest of the day.... anyway I report than all guest have been pleased with many tarpon on line, and good size fish 80lb/250lb, Several Guests also had nice snook over 25lb Most of Fishing has been in front of our new confortable lodge in Saballo.there we almost ..” catch tarpon from deck” . I like to specifically mention a tarpon we estimate around 250lb tarpon on for guest Lindy , a fishing guide from Florida... This tarpon was almost Black on the back and Golden on the belly, it belong to the category of our “resident tarpon” , these in my opinion do not migrate they stay there for at least several year in the fresh water of San Juan River or Nicaragua lake, reason of their colour... ( About Lindy the fishing guide from Florida , he is really a very nice person , and no doubt a great Guide, we exchange ideas and also learned from him...It’s boats are based in NAPLES FLORIDA If any one is interested to know him his web site is at Tarpon and snook Fishing is going to be almost the same in coming weeks and months on our grounds of Santa fe, El Pitasso, Saballo all in San Juan River .....meaning Guest will have many tarpon on... Talking about season .We are actually ( Till May ) in the so called DRY SEASON , time of the year when we are very busy as it is the traditional winter time vacation for our friends from USA..Talking weather we have Sun, and sometime strong wind ( Good we are fishing in quiet rivers ...) This does not mean than we do not have rain... Few it’s a fact but still a bit and we apreciate it, we want it... as during this rain Snook bite , after the rain tarpon bite...... CONCERNING THE RAINY SEASON ( May to November ) I like to say than , even if we are in a tropical area , here this is not the “deluge”, we have rain and sun and Rain and sun... ( Guests need to bring sun screen and also rain gears...) seriously this is very good for fishing... also traditionally this is a time of the year when we have less guest...pity because it is also a time of the year when we probably have perhaps an even better fishing as the level of the river is growing...( at this time of the year we have our resident tarpon plus more migrating ones than usually these fish going down or up river??!! ) My operation is small I only can receive a maximum of 8/10 guests at a time , Usually each week I have 2 to 6 Guests “ Who know well each other before the trip” in my expeditions... I take the oportunity of this E MAIL to advise than I have some opening on my schedule : If February is full I am able to receive Guests in March and obviously folowing months...witch are also very good with a special mention for June, July, August, September ( Low season for us concerning number of Guest not for fishing it is also very good then, may be even better ) San Carlos Sportfishing on line: English sites : French site : Email: [email protected]

Black Mollys
Posted on: 29/1/2003 16:32:00

Hi I got some black mollys from the pet store and one of them was pregnant. She had about 15 babies but the strange thing is that one of the babies is completely white. I think that he is an albino. Are they rare? Will he become black later on? Do albino fish live for very long? I've never heard of one before I can't find any information about albino, black mollys. Please help.

Brown trout - Salmo trutta
Posted on: 29/1/2003 11:05:00

I am looking for imformation concerning the common names of Salmo trutta forma fario. There are different morphological forms of the Brown trout. Some have red and brown spots, whereas others only have larger brown spots. How do you differentiate between these forms? Could one be the European brown trout and the other the American brown trout? I have been told that the common name of the brown trout with only brown spots is Lochleven brown trout, but cannot find literature conferming it.

There are a variety of different (morphological) forms of Salmo trutta fario. Some fish populations have red and brown spots, and others only brown spots. Does these forms have different common names, or how can do you differentiate between these different forms? Could one form be American and the other European?

Fishing in the Baltic Sea
Posted on: 22/1/2003 08:32:00

The Baltic is a small almost closed sea with civilized nations on all sides of it. Still the use of trawlers is still allowed. The cod population is rapidly disappearing and that is just the beginning. Is there any hope that this important Sea can be saved?

Jawfish Identification - Cozumel
Posted on: 3/1/2003 04:39:00

Hello, Looking for some help identifying this jawfish that was spotted in Cozumel, Mexico. This Jawfish was approximately 4" long, with a pale body and a very dark head with a blue ring around its eye. Very similar to a Yellow Head Jawfish, but without the Yellow colouration. I could find no reference to a jawfish with a color phase this dark, or with this colouration. I have an image available of this jawfish - unfortunelty you can only see the head and not the long body. Hopefully it helps someone recognize this fish. Thanks, Marriard
