Bacteria-eating fishes
Posted on: 30/12/2001 14:46:00

I'm looking for the name of a certain bacteria-eating fish. People will go and lie in the water where these fishes live (somewhere in Europe) and let themselves get "cleaned" by these fishes. These fishes eat the bacteria right off a human body. I'd like to know the name of this specific fish. Can anybody help?

Order Gymnotiforme
Posted on: 22/12/2001 11:18:00

Congratulations on an excellent resource. I wasn't sure where to post this, but there may be a potential problem with classification for Gymnotiforme families. I'm posting here because I not only wanted to alert you of the problem, but I also would appreciate clarification. You have Gymnotiformes listed as having 6 families, but the only ones on the database that I can find are these 5: Gymnotidae Rhamphichthyidae Hypopomidae Sternopygidae Apteronotidae You also list the family electrophoridae, but have no genera/species classified under its "Family Info." My conclusion is that you list 6 species instead of five because electrophorus Electricus and electrophorus multivalvulus are often given family status (electrophoridae) instead of Genus status (electrphorus) within the family Gymnotidae. So, my question is whether I am correct in classifying Gymnotiformes as having only 5 families if I include Electricus and Multivalvulus in the family Gymnotids, or whether there is another family among Gymnotiformes that I have missed. Thanks, and Bravo again.

Growth in tank
Posted on: 21/12/2001 11:46:00

I've read that placing a fish in a tank too small for it will stunt it's growth. How does this happen? Does the fish then become distorted or merely remain smaller. I also heard in relation to this that fish don't grow the same way we humans do; they continue to grow until they die. If this is true why aren't all fish gigantic? Is there size predetermined by their genes so they can grow only until they hit their peak? Thnaks for any help you can give!

Can you spot the difference in appearence when you see one?? If anybody knows this I would be happy to know. Many regards Lars Bindholt

Researchers on sabbatic on tropical fishery
Posted on: 15/12/2001 21:24:00

Our School of fisheries invites researchers for a short term period ( two weeks to five months) who are in tropical marine fishery. The school is located in a fishing village facing the Pacific Ocean in southern philippines. We can take in only one at a time. What we can offer is the use of the school fishing grounds. The faculty can partially assist in the research as a mode of staff development for them. Board and lodging will be charged at minimum cost - USD 150 monthly. The researcher has to bring his laptop/notebook. The place is peaceful. In fact we have invited a VSO in marine biology for a fortnight; we also have a VSO for media technology (video production, graphics for brochures, etc) whose trem with the school is for two years.

Aerial Surveillance: The Human Ecology of Salmon S
Posted on: 6/12/2001 07:00:00

Research indicates that purse seiners (back in the 1980s) caught 80%-90% of the vulnerable migrating salmon present in Johnstone Strait during what were commonly 48- or 72-hour fishing openings. In British Columbia, Canada, salmon purse seiners line up at fishing access points, forming well defined queues. These queues were measured over time in Johnstone Strait using a one dimensional recording scale. Sixty-one overflights of the fishing area were attempted; 51 flights were completed.

what kind of minnow do i have?
Posted on: 17/11/2001 17:48:00

hi guys! i am having a lot of difficulty figuring out what kind of fish i have! i am a student worker at my college in central ohio. i work in the biology labs taking care of all of our animals. included in our collectio are a freshwater tank and a reef tank. last week, one of my professors brought me 3 freshwater minnows (that's what he called them) he found and i wanted to make a tag for them like we have for the other fish in the tanks with common name, picture, scientific name, and native habitat(s). too bad i have NO idea what he has brought me! the minnows i can find that have the same markings, do not have the same fin configuration! the ones whose fins look right are from a totally different region of the world or have different coloring! i am so confused! i will try to give you guys the best description i can and hope someone can tell me what it is! if there are any ohio fishermen here, i'd love to hear from you! :) okay, here goes: -- small, maybe 5 cm long (don't know how old they are, though) -- 2 dorsal fins, 1 long and flat (sometimes 'stuck' to the body), the other long and flat also but more of a triangle shape at the same time. -- 1 anal fin, triangular. -- 1 pair of fins behind the gills. these are relatively small. -- 1 pair of fins behind the gills and under the body more. smaller than the fins behind the gills. -- fish is a light brown, thin darker brown line down it's side (head to tail) with darker brown scales here and there above the line. -- rounded head with mouth kind of on bottom of head -- not a rounded tail fin, more like a goldfish tail fin (you know it looks like 2 tail fins - i don't know what it is called, sorry). -- stays at the bottom of the tank if you would like to see a sketch i made of it, go here: (please keep in mind i am a BIO major, not an art major! ;) ) i thought it might be a bluntnose minnow, but they only have 1 dorsal fin and no darker brown spots above the line. i also thought it was a johnny darter, but the dorsal fins are flatter, there is no darker brown line, and i don't think the dorsal spines (is that what they are called?) are as obvious. i would appreciate ANY help! THANK YOU!

Toadfish ID
Posted on: 15/11/2001 05:12:00

I recently acquired a fish from my local pet store that was labeled as a "freshwater lionfish." (it is being housed alone in a strong brackish tank, specific gravity of 1.012) I can only find 2 references to this fish in the aquaria books I have here at home, and they both state it is a Halophryne trispinosus. However, in Fishbase there is no such fish. I would very much like to identify this fish beyond the family Batrachoididae. As it is nocturnal in a tank w/ lots of cover it is very difficult to get a good look at it (impossible to count rays, ect..) Does anyone know what species of toadfish is commonly available in the pet trade? Thank you for your time.

snapper versus sparid
Posted on: 13/11/2001 03:47:00

hi all, I've been asked to identify a fish recently taken from a fishsellers that was labelled as a red snapper... Using fishbase and kind help from various people on the fish-sci mailing list, i have managed to id the fish as a sparid bream. it is similar to Pagrus pagrus, although the head seems somewhat blunter. I'd love to make a final identification, but all I need for now is the definite knowledge that it is NOT a lutjanid. Do all lutjanid fishes have a serrated edge to the preopercule? cheers in advance C

Aspidontus taeniatus
Posted on: 6/9/2001 17:08:00

I have seen two specimens of this sp. (?possibly Labroides, although I usually can tell the difference)in Eilat (Red Sea). They showed clearly their dark frontal dorsal spines much longer than the rest (forming an erectile crest/flag), popping for short duration (possibly males displaying?). I know that some blennid males have longer frontal crests, but could not find any reference in littereture to this in Aspidontus. Is this a sign to differentiate it from Labroides? Does Labroides have dark, long spines?

Identification of various "piranhas"? (3)

On a trip to the Amazon River/Rio Negro near Manaus, Brazil last year we caught/saw several different kinds af "piranhas" and related fish. Can anyone help me identify these fish from the attached pic's? I think that perhaps these next 4 pictures are all "Redeye piranha" (Serrasalmus rhombeus) of various ages? "Pirat3&4" would be juveniles (3 older than 4) and "Pirat5" adults. "Pirat6" is a closeup of the teeth of one of the fish from "P5".

"Pirat9" should be a Slender piranha (Serrasalmus elongatus). And "Pirat10" should be a Tambaqui (Colossoma macropomum). Can anyone confirm this?

preffered velocities
Posted on: 17/8/2001 11:18:00

We do a variety of work with environmental restoration as well as parks and on occasion have the opportunity to help "create" new streams and/or affect significant changes to existing urban streams. This includes the ability to impact water velocities. I have read some literature about specific freshwater fish species and velocities, yet the data seems to be based on the point at which a fish stresses or "gives up" swimming against the current for the test period. No where have I found data on "preferred" velocities. Is anyone aware of if such data exists and where it can be found? If no data exists, I would certainly encourage a young researcher to entertain this for a research project! Not only would it help my situations but would also give us a better understanding of the impacts to community composition of altering any streams velocities. Thank you.

Puget Sound fish

The curiousity is killing me! I was pokin around an oyster bed during low tide and was overturning rocks and whatnot, enjoying watching the insane number of crabs scurry for the darkness when I found a curious fish. It looked like a gazer of sorts. Smooth black scaleless skin, like a catfish. Upward facing eyes and mouth. The mouth was very wide and very full of teeth. The belly was off-white. This fish was burrowed underneath a rock, with no water. It pectoral fins were adapted to be used like limbs. It had a long, singular dorsal fin. I have it captured on video. We found a couple before the adventure was over. Any ideas as to what this was?

Piranhas in PNG?
Posted on: 19/6/2001 06:07:00

There is an interesting story about freshwater fishes in Papua New Guinea (PNG) at present. At the PNG National Fisheries Authority we received specimens of a freshwater fish brought from the Sepik River (one of the two largest rivers in PNG) reportedly to have been biting and injuring people in the region. There is speculation among people that the flesh-eating Piranha of S. America must be here in PNG, but how (if it's true?). It is a concern right now and we are working to identify the fish species and gather more information about the possible ecological impacts the fish (possibly introduced) is causing to the Sepik River. I thought that it would be useful to check Fishbase of introduced fish species in PNG. I also thought that it would be interesting to report to you and Fishbase about this information and when we really get the fish identified (presumably Piranha) than it may be included in Fishbase as an introduced species in PNG. Meanwhile I need some advice on a possible museum in the world to send the specimen to for identification (if necessary). Photos of the fish specimen from the Sepik River are attached. I wish to keep you informed about this when I gather further information.

boneless fish

I am teaching a sculpture class to 10 to 13 yr. olds. I had them make a self-portrait of what animal they think they are. One girl made a fish. I suggested she give the fish fins, and she said she was making a bonless fish without fins. I asked her is she was making a shark. She told me of all the fish without bones. Are there fish without bones and are they actually fish and not some other form of marine life? I need to know. thank-you?

Sharks in danger in the Galapagos Islands!!!
Posted on: 6/6/2001 10:42:00

Galapagos: Over 1,000 Shark Fins is still not enough … May 27, 2001 The future of the sharks in Galapagos lies in the hands of one judge. Are we going to let this happen!! This year alone there have been 18 boats captured within the Galapagos Marine Reserve. In Santa Cruz Island alone there are 18 judgments for illegal fishing and 3,000 shark fins were decommissioned. In San Cristobal Island there are 25 court cases with 1,980 decommissioned and 3,000 pounds of shark meat. Over 1,000 shark fins were released along with the poacher, Ecuadorian registered Japanese class long liner named Dilsun, by an order made by a port captain on the island of Isabela. Another 1,000 shark fins captured by Costa Rican long liner, the Maria Canela II, is about to go unpunished by a judge’s ruling. What will it take for people to start reacting strongly against this cruelty? I am writing this article from onboard the Galapagos National Park patrol boat, Sirenian, and we are continuing to patrol the marine reserve despite these actions taken by the authorities. I am frustrated though. The Sirenian has captured four boats in less then three weeks and three were already released and the last one is about to be let go after having been caught illegally fishing shark within the Galapagos Marine Reserve. The Maria Canela II was caught with over 1,000 shark fins and just 78 shark trunks onboard. You do the math, over 1,000 shark fins would correspond to over 200 shark trunks. Not only were they hunting shark illegally they are pirate shark finners, a practice expressly forbidden according to the Ecuadorian law and most other places as well. Shark finning is the act of cutting off the shark fins, usually while still alive, and discarding the rest of the body. Over 99% of the shark is not used. All this waste to feed the rich minority in the asian markets. If that was not enough, we also caught them with over 25 miles of long line laid across the marine reserve just off the coast of what is considered one of the 7 greatest underwater wonders of the world, Darwin Island. We picked up the entire 25 miles of long lines, which are strictly prohibited in Galapagos, and found between 6 to 10 live sharks dangling from it. It was a perfect bust in my eyes. Open and shut case. This was a foreign registered industrial long line fishing vessel hunting exclusively shark fins. All aforementioned facts are illegal within the Galapagos Marine Reserve. The laws do exist and the National Park is applying them with force. Why then are these poachers being released? The answer is simple. There are huge economic interests involved whom are influencing people from judges, port captains, admirals, to even the minister of the environment who has recently resigned. How can the Galapagos National Park, known as the greatest national park in the world, going to effectively safeguard one of the greatest world heritage sites if this is allowed to continue. The sharks in Galapagos are worth more alive then dead according to Mathias Espinosa, naturalist guide and owner of one of the top dive shops in Galapagos, Scuba Iguana. “People come to Galapagos exclusively to swim amongst the sharks”. He has been diving the Galapagos Islands for over 13 years and has witnessed the decline of sharks year after year. In speaking with him he has recounted many stories where tourists from around the world have arrived with what I dub as the “Jaws Effect” and have left with a total understanding and appreciation for one of the most graceful examples of evolution. I recently spent some time with Patrick Symmes, renowned writer and author, about his experience with diving amongst sharks in Galapagos. He had no idea that in the first day of diving with sharks he would be totally transformed about his views of sharks. Many similar stories have been told here in Galapagos. I ask the local people here in Galapagos to voice their opinion and help safeguard the symbol of their Islands, the Hammerhead Shark. The shark is an icon and one of the major reasons tourism exists in Galapagos. There is even a shark named after the islands and the sharks are one of the most ancient species today and should be a deep-rooted part of the traditions and cultures of all people in Galapagos. I ask the people of Ecuador to voice their opinion and help safeguard their greatest treasure and National Heritage Site, The Galapagos Islands. All Ecuadorians have the responsibility to protect the Islands so that their children and their children’s children can also know Galapagos as you know it today. Express your concerns to the president and stay informed. Do your own investigation on what is happening with Galapagos Islands. I ask the people of the World to voice their opinion and help safeguard one of the last untouched wilderness areas and one of the most unique places on this Earth. Galapagos Islands is listed as a World Heritage Site according to UNESCO. I say what good is it to be listed as a World Heritage Site if practices such as those aforementioned are allowed to continue. If UNESCO is not willing to get involved then the title of World Heritage Site is nothing more then an empty label. Perhaps it is time for representatives to come down and re evaluate this World Heritage Site. Will the release of Maria Canela II be the point of no return or will it be the one decision that the authorities regret. YOUR actions today will dictate one or the other.

Pop-eye mullet
Posted on: 28/5/2001 00:55:00

Can anyone help with scientific name and/or biology info for this mullet found (at least) in the Kimberley region of Australia. Known locally as "pop-eyes" these fish inhabit estuarine areas (usually seen in shallow water), seen to 25 cm in length, very obvious becuase of their eyes protruding from top of head (ie. "popping" out) and behaviour of preferably swimming at surface, in schools, and tendancy to jump numerous times if frightened. Very popular for live-bait of barramundi (Lates calcarifer). I don't believe it is Mugil cephalus, Myxus elongatus, Liza vaigiensis, Liza subviridis or Liza argentea. Thank-you

Unknown fish in Palau
Posted on: 25/4/2001 04:32:00

While diving in Palau, I encountered a pair of fish which I am unable to identify in your database and wonder if anyone could suggest what they might be. The fish were of similar size and shape to cardinalfish and resided in a degraded, rubbly section of reef at about 10m depth in broken staghorn coral. They had longitudal body stripes which were alternately orangey brown and cream in colour. They had vivid powder blue spots surrounding their eyes. When approached, they hid their heads in the coral, but left their tails sticking it, presumably because their eyespots spoil their camouflage. Any ideas?

Stinging fish. But which one?
Posted on: 17/4/2001 06:32:00

Hi, I just arrived from a Holliday to the Canary Islands' Fuerteventura (Spain). On one of the beaches there I managed to step on some kind of a venomous fish. It felt like a stinging wasp only deeper and a bit more painful. The depth was about 1-2 feet (50 cm) on sand bottom. I believe the pin or fin that penetrated my foot was about 1-1,5 inch long. I only got one sting, so it has to be a fish with only one pin/fin on the back. The pain lasted for at least 4-5 hours and I was swollen and limping for 3-4 days. I'm just curious what the fish looks like or what kind it is. Does anyone know? Thanks.

Crossed eyed fish or tadpole?
Posted on: 1/4/2001 22:06:00

Please "hear" out my question before anyone thinks what a wack-o I am :> We live in Northern California and in Napa County there is a place called Conn Dam. 30 some years ago when I was in 6th grade on a field trip there was a stream fish that had an eye on each side of its little body like all fish are, but it was crossed eyed. Thank goodness they don't allow this anymore in schools, but we, as the class, caught some as a project. Now, is the part no one will believe, but honest it happened! These little fishes could grow a new head from the tail if it was cut off, and the head would grow a new tail. If the head was sliced, it would be two heads, 4 eyes, one tail. I can not remember the name and if this post doesn't get deleted by the web master I hope some fish expert can help. We are heading up to Conn Dam in the next couple weeks and I was telling my husband about the field trip and here I am! :> Thanks much!

ID for strange pacific north west fish
Posted on: 12/3/2001 21:27:00

Hi guys/gals, Was night diving near Vancouver, BC Canada yesterday and came across a very strange eel/snake like fish. It was free-swimming about 5 feet below surface in about 20 feet of water but close to some large rock pilings. The fish was 2 to 3 feet long and very skinny - very much like a compressed garden snake in both shape and movement with a dorsal fin running the length of the fish - was balck with while/dull grey stripes (horizontal)in colour. The strangest thing about it was it's thin elongated mouth (3 to 4 cm long) where the upper lip/jaw curved gently upwards while the lower jaw curled gently downwards. Haven't been able to figure out what this fish was but we got a very good look at it for several minutes - probably because of our bright lights. Any help with this ID or where I might look for further info much appreciated.Thanks in advance. chris

Piranhas in the former Soviet Union???
Posted on: 11/3/2001 13:49:00

I was watching some quiz show on TV the other day, and the contestants were to say if a given statement was true or false. One was that there are piranhas in the (I think) Caucasus region in the former Soviet Union, and the guy said "No" (cause that makes sense to me as well). But to my (and the guy's) surprise, they said it's TRUE, that there ARE piranhas there! That sounds like a joke to me but that's what they said! Can anyone here confirm that it's really true, and if so, where do they come from? How can a South American species live there? I still won't believe it until someone can confirm this.

Pacific Northwest fisheries
Posted on: 11/3/2001 08:38:00

I am involved in salmon conservation out here on the west coast in Oregon. After browsing this forum I have come to the conclusion that it is full of very knowledgable individuals. My question is this, does anyone know where I could find information on the ability or inability of hatchery raised adult salmon and steelhead to spawn naturally and successfully in Northeaastern US streams, or western streams for that matter? The recent debate suggests that the single most important factor limiting wild stocks in the west from a comeback is the presence of hatchery fish which are unable to successfully reproduce, supposedly. The argument goes that these hatchery fish attempt to spawn with wild fish, but when breeding is unsuccessful the population is extremely impeded. I am looking for infoirmation that would support this argument. Any help is gratly appriciated.

Impact of Barrier Net Trap
Posted on: 7/3/2001 01:00:00

Dear All, I would like to know the opinions of this forum concerning the use of Barrier net for catching wild post larvaes (Pl's)of fish. In South East Asia, the trade of live fish (for aquaria and human consumption) is a very big business. Many people use poisons (cyanide) and bombs to catch fish alive. At the present time, the reef is extremely damaged in many area. The population of grouper (such as Cromileptes altivelis) and Napoleon (Ceilinus undulatus) is drastically decreasing. The fishermen use to catch groupers when they rally for breeding! Furthermore, napoleons are caught when they are still small (around 800 gr.) and they don't have the time to multiply. It seems also that the customers start to realise that these fish contain traces of poison!!!! Th situation is so bad that people who are involved in this business are now asking to find other solutions and would like to rear these fishes. The cost of construction of hatcheries is quite onerous and is not conceivable for them. Thus, by using barrier net it will be feasible to catch wild Pl's and to grow these fish in tanks or in cages. This method could enable local fishermen to grow their crop rather than to risk their live (diving) and to destroy thier own environment. What will be the impacts of this method on the ecosystem? Do you think this method is feasible and could be a good alternative system? I hope my english to be enough clear. I am looking forward to read your reactions conncerning this subject. Cheers, Chromileptes

I have recently been diagnosed with chronic ciguatera. I am searching for vectors of transmission other than "eating" fish or seafood. For example, handling of viscera & roe of contaminated fishes. I know that the ciguatoxins are more concentrated in the organs and head of the fish than in the flesh of the fish. Therefore I believe there is a more potent vector of contracting ciguatera than ingestion. At this point in time I have found no research material which suggests that ciguatera can be transferred via handling of the organs of ciguatoxic fishes. Any info. avaliable?

Mysterious fish from the deep!!!
Posted on: 7/2/2001 09:04:00

Hi all This should intrigue you. A message I received from a member of the public (I am a fish collection manager with a museum in the States). We all had a good laugh. Anyone have any ideas?? Herewith follows the message. ------------------------------------ I am trying to identify a fish that attacked my girlfriend, i have compiled a partial description of it, and the location of the incident, and if you can shed any light on it, id be much appreiative. The incident occured at Fort Walton, Dresdin. in the later half of 1998, after a hurricane had been through. The beaches were strewn with seaweed, kelp? and sea snails/slugs. My girlfriend went for a swim, but was covered in these fish which bit her. She hurried out of the water and into a shower, and the fish died. The fish are described as: about half an inch long, clearish/translucent, wish very prominent teeth- i think like a pirhanna not sure, but possibly. It appears they hunt in schools. Each fish had to be removed once they died in the shower, because they were still biting her. Shortly afterwards she developed an itchyness and severe rash - which we are contemplating being related. It is my theory that these fish being colourless were probably from deep waters and got stirred to the surface by the hurricane. I havent been able to track down a fish that matches the description, not reports of similar incidents - though there was one page talking about a fish biting incident, but the link had since gone dead. Any light you can shed or help you can give on the matter is greatly appreciated. --------------------------------------- Hhhmmmmmmmmm!!!!!!!

Scardinius erythrophthalmus
Posted on: 6/2/2001 01:09:00

I'm looking for some Scardinius erythrophthalmus (rudd) specimens coming from different European countries. I'm working in a project involving philogenetic analysis of the populations of this specie. I would greatly appreciate if someone could help me to get them. Obviously, in case, the way and the cost to deliver me them will be my duty. Thanks for your courtesy Fabrizio

I was wondering if there any experts out there who know, with any degree of accuracy, the kinds of fish that can be found in China's coastal waters, particularly the Bohai sea. Thank you for your responses

I'm looking for info about a freshwater fish called Dorado in South America, it's probably related to the Salmonides (according to the article), it's pretty stocky built and the color is kind of golden. I saw it in an ABU Garcia catalog from 1983, I still have pics of it, but I can't seem to find any info about it on this site. Does anyone know what species I'm looking for?

sono un pescatore con la mosca e pesco sia inacqua salata che in acqua dolce. forse non sono la persona più adatta per parlare in questo bellissimo sito,ma vorrei chiedere alcune cose e se non vi disturba qualche idea. ho cercato la diffusione dei tarpon e dei bonefish, e ho trovato un po approssimativa la cartina (capisco bene che parlo con super esperti ed io sono un povero ignorante), ma ci sarebbe qualcuno disposto a darmi informazioni più dettagliate su alcuni pesci? sono stato a pescare a cajo largo a cuba vi interessa sapere cosa ho visto e pescato? un suggerimento è proprio questo , per capire bene la diffusione di certe specie non potrebbe esservi utile avere informazioni da pescatori? conosco un ittiologo che lavora presso la mia città all'ufficio pesca , (abito a Verona, nel nord Italia, vicino al fiume Adige dove si trova ancora la trota marmorata e il carpione sul Lago di Garda), vi interesserebbe contattarlo? scusate per il disturbo di un'appassionato più di pesci che di pesca e complimenti per il bellissimo e completo sito. grazie a chi mi risponderà

# of fish on earth?
Posted on: 16/1/2001 01:58:00

Hello all, I'm a science journalist in Toronto, Canada ... and I'm hoping someone here will be able to provide an answer to my query. I'm working on a script which refers to the number of fish on earth, particularly as compared to the relative number of humans. Trouble is, at the moment, I'm still searching for the appropriate figure. The usual suspects (Encarta; Essentials of Oceanography; The Oceans: A Book of Questions and Answers; Life on Earth, etc) turned up figures for the estimated numbers of species, but none for total population. If YOU know, do tell. Please cite appropriate reference in your response, if possible. Thanks in advance for your help, Louise

mystery fish
Posted on: 15/1/2001 14:01:00

Has anyone ever heard of a "tutti frutti tetra"? They come in a variety of brilliant colors, but, I'm told, turn silver as they become mature. They were recommended for my daughter's first aquarium, but I haven't been able to find any refernce to them. Perhaps they're known by a different name?
