Food anticipatory activity (FAA) was assessed in rainbow trout (Oncorhynchus mykiss) in two small raceways using demand-feeding (T2) and hand-feeding (t2). The fish of both raceways were subjected to
restricted feeding (RF) at two times in two places and the fish distribution and/or trigger actuation, total agonistic behaviour between fish, and swimming speed were measured. Food anticipatory activity did not appear clearly when using the usual measures. The present study suggests that the expression of FAA is not limited to trigger actuations, fish positioning or swimming activity but may also be described by swimming speed and agonistic behaviour.
