Abstract

Grass carp fry (0.04±0.01 g avg wt; 1.48±0.03 cm total length) were stocked into an earthen pond in June. Every week for twelve weeks, fifteen fish were sacrificed and the content of their guts was examined. At the first week, animal material represented 74% of the gut contents. From the second week onwards, plant material was higher (mean value 79%). In the seventh week, when grass carp reached 4.83±0.09 cm, filamentous algae were replaced by macrophyte frag- ments. Besides the macrophytes, animal material such as the rotifers Monostyla and Lecane and the cladoceran Bosmina were found and the proportion of animal material in the gut varied 11-26%.
