Periodic reinforcement of acoustically conditioned behavior in St. Peter's fish, Sarotherodon galilaeus, for ranching purposes

摘要: Abstract Periodic retraining of St. Peter's fish for retention and reinforcement an acquired acoustically conditioned behavior after initial training period 28 days was studied. Four periodic paradigms were tested, each lasting 54 days (paradigm 1 × 3: one event every 3rd day; paradigm 2 × 6: two events 6th 3 × 9: three 9th day). The objective to study the effects time interval between sessions number comprising a session. No significant differences found paradigms: all resulted in similar response. Since it had been shown (in our previous work) that is totally lost 6 months, ability maintain their responses this using 17 days with six (three per day 2 consecutive days) tested. Fish response indeed maintained at high level throughout 6-month period. conducted context sea ranching which classical conditioning used gain control over location attract them feeding location. Such concept feasible if can trained long grow-out periods required growth marketable size. present proves method retaining maintaining periods.
