Who C.A.R.E.S…? Aphanius transgrediens

Here is a video of another endangered fish I am maintaining.  I have not had these killies very long, and have just recently been able to collect and hatch viable eggs.  The fry are growing fast though!

A few years ago I had the great pleasure of visiting the Aphanius sp. maintenance facility in the basement of the aquarium building at the Wien Zoo (Vienna, Austria).  I was not there to see the killies, and had no clue that they were even there.  What a surprise!  The program maintains more species and locational varieties of Aphanius than most of us even know exist.  Some of these little fish are spectacular, and I have been on the hunt for them ever since.

The genus is found all around the Mediterranean Sea, and all the populations are considered threatened in the wild.  Some, like the A. transgrediens in this video, are critically endangered (if not already extinct).  One species, A. mento, is relatively common in the U.S.A. hobby… and it is an excellent species to work with.  All the other species are very rare, and I thank my friend Kurt Z. in Missouri for sending my founding group to me.

“Who C.A.R.E.S…?”   This is a challenge… if you are not keeping at least one species of fish that is at risk of becoming extinct, please find a species that interests you and make the commitment to keeping them for as long as you can.  And breed and distribute them.  Check out the C.A.R.E.S Preservation Program to learn more.

  1. These are super fish. It really does sadden me to know that every single day the world looses species of fish! I think its a grand idea to breed these fish and keep them around, I only wish that more could be done to keep the wild populations of all wild fish intact!

  2. Are there any groups of Aphanius enthusiasts in the US? I have kept a few species and would love to get more, but have had trouble finding other Americans who keep aphanius.

    1. The first place to look would be the American Killifish Association, and then look for local killifish clubs. THer are more of them out there than most people realize. The AKA has a list of local clubs. You can also try Aquabid.com, but they are uncommon on that auction site.

  3. A group of turkish ichthyologists have some efforts to protect Aphanius transgrediens, hope that we shall be successful

  4. This one, and some other Turkey natives, may very well survive outdoor in USA, probably up to southern KS. Pond propagation would be much more effective.
