Última Relationship between individual and group learning in a marine teleost: A case study with sea bass under self-feeding conditions ArchiMer Benhaim, David; Ferrari, Sebastien; Colchen, Tatiana; Chatain, Beatrice; Begout, Marie-laure. Fish learning and cognition are usually approached by testing single individuals in various devices such as mazes that have serious drawbacks, especially in gregarious species, including the stress induced by the test procedure. This might impair the results and lead to misinterpretation about the learning abilities of the targeted species. In order to provide an alternative to the individual-based tests, we investigated for the first time the operant conditioning of four similar groups (50 individuals per tank) of sea bass. We used two computerized self-feeder devices per tank, each coupled with individual electronic identification and that were alternately activated during varying positive appetitive reinforcement period of time (7 to 1 day).
