Influences of food distribution on fish foraging behaviour

Article Abstract:

A study of the foraging behavior of the juvenile walleye pollock, Theragra chalcogramma, showed that fish foraging behavior dependent on the type of food and the form of food dispersal in the environment. Juvenile walleye pollock which have acclimatized to dispersed food preferred to forage alone, while those which were acclimatized to clump food preferred to forage in groups. The results suggest that foraging behavior in the juvenile walleye pollock was more dependent on food distribution than on social interaction.

The behaviour of capuchin monkeys, Cebus apella, with novel food: the role of social context

Article Abstract:

The social facilitation in Capuchin monkeys, Cebus apella, increases their consumption when the food is novel than when the food is familiar. The experiment was conducted on monkeys in the individual condition and in a group social condition with familiar food and novel food. In the social condition, the novel food eaten is more than in the individual condition, but the consumption of familiar food is not affected. The individual is found to be attracted towards another individual's food when the food is novel.

Swimming and search behaviour in clownfish, Amphiprion perideraion, larvae

Article Abstract:

The swimming and search behavior of Amphiprion perideraion or clownfish larvae in relation to changes in their environment was observed. High abundance of food results in more complex and convoluted swimming patterns to exploit the patchy resources. The larvae swim in shallow turns and generate linear paths when there is low food density to maximize their encounter with food.
