Abstract

The results of two experiments showed that observation of a trained conspecific Atlantic salmon Salmo salar significantly increased the rate at which naive hatchery-reared fish accepted novel, live prey items, whereas the presence of an untrained conspecific actually decreased learning rates due to social inhibition. Pre-release training involving exposure of hatchery-reared fish to live prey items in the presence of pre-trained demonstrators would result in a significant enhancement in their foraging success on release and help prevent starvation, which is thought to be one of the principal causes of post-release mortality in hatchery-reared fishes.
