The University of Stirling in Scotland has conducted a curious test on the ability to learn fish. In their fish farms, before giving food each day, they emit a certain sound as a stimulus. It seems that flat fish are the most skilled to know the sound.

For its part, cod has little facility to guess these sounds. The results of these studies open a way to help endangered species. A species can be sturgeon, as there are usually feeding problems.
