Prey size selection by common carp ( Cyprinus carpio var. communis) larvae in relation to age and prey density

Common carp ( Cyprinus carpio) larvae at different ages up to 30 days were offered prey of three different size classes (rotifers and cladocerans) at different densities in the range 25–400/l. The proportion of larger prey in the diet increased with age. At any age, prey size selection was related t...

Summary:Common carp ( Cyprinus carpio) larvae at different ages up to 30 days were offered prey of three different size classes (rotifers and cladocerans) at different densities in the range 25–400/l. The proportion of larger prey in the diet increased with age. At any age, prey size selection was related to prey density; at low densities all three sizes were taken as encountered, but with increasing prey density the larvae selectively captured larger (more prcfitable) prey.
