Increased growth rate in Atlantic salmon parr by using a two-colour diet

Fishes hunting by sight are known to pay a cost of confusion when faced with high densities of uniform food particles. In such instances, awareness of other stimuli reduces feeding efficiency such that the fishes prefer low densities of food particles. Farmed Atlantic salmon parr (Salmo scalar) with...

Description
Summary:Fishes hunting by sight are known to pay a cost of confusion when faced with high densities of uniform food particles. In such instances, awareness of other stimuli reduces feeding efficiency such that the fishes prefer low densities of food particles. Farmed Atlantic salmon parr (Salmo scalar) with agonistic behaviour, have the additional pressure of conspecific aggression while feeding.
