Interactions between shoal size and conformity in guppy social foraging

Article Abstract:

Foraging innovation in the guppy

Article Abstract:

The innovative tendencies of guppies, Poecilia reticulata, were investigated, involving exploration and problem solving to locate a novel source of food. Foraging information has previously been demonstrated in guppies. Three factors that influence foraging innovation, sex, hunger level and size, were identified. Females were more likely to innovate than males, and those deprived of food were more likely to innovate than those not deprived of food. Also smaller fish innovated more than larger fish, suggesting that motivational state is the main factor underlying guppy foraging innovation.
