Innate predator recognition in newly-hatched Atlantic salmon
Abstract It is well established that fish can learn to associate odours from potential predators with risk and alter their behaviour accordingly. However, newly-hatched individuals have few opportunities for acquired predator recognition and may depend on unlearnt (innate) responses. We therefore co...
