Abstract
In Conowingo Reservoir most of the food consumed by young white crappie over one 24‐hour period was eaten during daylight hours, most of it during the morning and early afternoon. The maximum number of organisms was present during mid‐afternoon. Daphnia spp. and Cyclops spp. were the most important food items. The consumption of these items changed significantly over the 24‐hour period of study. It was estimated that the food items eaten by young white crappie passed through the stomach in 14 to 17 hours. Data on seasonal food studies of young white crappies indicated that they fed exclusively on zooplankton in most months. Daphnia spp. were important in the diet in June through October. Cyclops spp. were important in September through April. Chironomid larvae and pupae were most eaten in April and May. Bosmina sp., Leptodora sp., Alona sp., Diaptomus sp., amphipods, mayfly nymphs, and algae were also eaten seasonally in small quantities. The diet was more varied in late fall, winter, and early spring months than in the summer. Feeding activity was highest in May through October.This publication has 0 references indexed in Scilit:
