The nature of prey selection by planktivorous fish is presented as a model. The model conceptualization is based on the predation cycle, and the effects of prey distribution, encounter rate, handling time, capture success and optimal foraging on food selection are explicit. The model as presented assumes a multiple species prey assemblage admitting within-species size variation. Conditions are given so that the optimal strategy of prey utilization can be expressed as a breadth of diet, and the specific components of the predator-prey interaction of fish and zooplankton are discussed in detail. A reduced form of model is applied to 2 experimental situations. Specific factors which influence prey selection are also discussed.
