Abstract

In this experiment, the FINGERLINGs of GRASS CARP reared under natural feeding of the pond were allowed to observe carp attacks on fully floating (pieces of bread) and sinking food (laboratory –made pellet). The performance and feeding starting times were then compared among carp-exposed or carp-observer GRASS CARP that could see the food directly with the demonstrators’ foraging activity and naïve GRASS CARP groups that couldn't see the demonstrators’ (common carp) feeding activity. The carp-exposed and carp-observer groups of GRASS CARP were better at feeding reaction (start time) than naïve fish when they fed on two novel fully floating and sinking food. When they fed on floating bread, 80% of the chambers of GRASS CARP with carp in compare with 53% of the chambers with only naïve grass showed starting taking food for the duration of 5 days. When they fed on sinking pellets, 65% of the carp - observer GRASS CARP in the tanks compared with 20% of the chambers with the naïve GRASS CARPs, showed taking the diet for the duration of 5 days. More carp-exposed GRASS CARP learned taking novel floating diet during 10 days experimental period and the observer GRASS CARP in the experimental tanks with sinking novel diet showed catching pellets 48 hour before the naïve GRASS CARP groups. The FINGERLINGs of carp-exposed and carp-observing GRASS CARP were capable of direct observational LEARNING in their FEEDING BEHAVIOR.
