Abstract
Feeding of chub fry of body length 1.0-8.0 cm in 3 heated lakes was studied. The fish fed on zooplankton (mainly crustaceans), insects and plants. Growing fish chose bigger prey. Only larvae (2 cm) ate Rotatoria, 2.0-5.0 cm long fry fed mainly on insect larvae and pupae, and fish over 5.0 cm preferred filamentous algae (90% of diet).
