Abstract

Experiments on sticklebacks seeking for food patches show that foraging in schools enhances food‐finding rate of individuals. A stochastic information‐sharing model characterizes food‐seeking behaviour in which food‐finding by one in a school of fish results in food‐sharing by many. The model predicts the food‐finding rate of a randomly selected individual in a school of n fish to be that of a solitary forager weighted by the inverse of the school size, 1/n. In sticklebacks this seems not to be the case, however. Though the food‐finding rate of individuals in the school reduces with n, the improvement is much slower than predicted by the basic model. We argue that a variant of the information‐sharing model accounting for interference among individuals affecting their food‐seeking behaviour fits the data better.
