Great Barrier Reef
Posted on: 28/12/1999 11:00:00
Hello,my name is Andrew Drown. I am undergraduate student at the University of Victoria in Canada. I am looking for a species index of coral reef fishes found in the different reefs of the Great Barrier Reef. I have found abundance indices, but have been unable to locate any diversity index giving numbers of species per reef. I was wondering if you might know where I could find such information. Thanks for your time, Andrew.

We are assigning reproductive guilds to fish families, using the following broad categories: bearers (=live bearers, mouth brooders, etc); guarders (guarding the eggs); nonguarders (open water / open substrate spawners). We are missing information for the families listed below. Please help!

Fluctuating asymmetry in Gudgeon
Posted on: 22/12/1999 04:14:00
Does anyone have information about fluctuating asymmetry
in fishes, more particularly in the Gudgeon (Gobio gobio)?
I also would like information about the 'DeLury'method. It's
a depletion method, in which one tries to catch as many fishes as possible
In each catch, the fishes are kept apart and are not released
until the end of the last catch. This method leads to a
depletion of the population number, which means that the
number of fishes caught in each catch will decrease. This
makes it possible to make a linear regression between number
of fishes caught in each catch (Y-axis) and accumulated number
of fishes caught in the previous catches (X-axis).
Like this, one can make a population estimate by calculating
the intercept with the X-axis. My question is : When one makes
this estimate, how can he calculate the 95% confidence interval ?
I haven't found any work in which this has been done.

Following a suggestion by FishBase users we opened this simple forum to provide a platform for information exchange on anything that has to do with fish.
And here is my first request:
We are in the process of assigning species to ocean provinces as defined by Longhurst (Longhurst areas). For this purpose we are looking for 'Checklists of Fishes' for the following islands:
Sao Pedro e Sao Paulo (=St. Paul's Rock, off Brazil)
Fernando de Noronha (off Brazil)
Isla Trinidade (off Brazil)
San Felix and San Ambrosio (off Chile)
San Fernandez (off Chile)
Ascension Island (South Atlantic)
I. Martin Vaz (South Atlantic)
Tristan da Cunha (South Atlantic)
Thanks for any help!
