EXPERIMENTAL STUDIES ON ZOOPLANKTONIC FEEDING OF SOME FISH FRY FROM. CERTAIN FRESHWATER PONDS AT ABBASSA, SHARKI A, EGYPT.

Abstract
Mass culture of live food organisms and formulation of artificial feed have gained much
importance to raise the required stocking material for fish hatcheries• and aquaculture. Growing of natural food organisms and their productiondn commercial scale are still in the experimental stage.
Experimental trials were carried out to feed Nile tilapia (Oreochromis niloticus) fry on different densities of natural food (zooplankton) and artificial feed (containing 25% protein). It is concluded from the results that growth response of tilapia fry varied according to the percentage of zooplankton and artificial diet used in the experiments. The highest growth rate was observed in fry groups fed on diet containing the highest number of zooplankton (5500 org.jfry).
A positive correlation was found between the number of zooplankton and the gain in weight and food conversion ratio of 0. niloticus fry. The protein content of the reared fry
