Abstract

This experiment was conducted from July to October 1993 at Abbassa farm, Abou-Hammad, Sharkia Governorate. The farm belongs to the Central Laboratory for Aquaculture, Agricultural Research Centre. Three-rectangle one hectare each (about 2.5 feddan) fresh water earth­en ponds were used in this experiment. The amount of natural food in the ponds was established by applying duck manure. Three treatments, 500, 750 and 1000kg per growing period were applied to the ponds. Frequency of applications were normally done every two weeks. Fish used were silver carp, llypophthalmichthys molitrix,. Number of fry stocked used in each pond was 10,000 fry per pond. Results showed that, growth performance of silver carp under the three rates of duck manuring was highest at the low level (500 kg/ha), followed by the high level (1000 kg/ha) in a decreasing order. It could be concluded that duck manure treatments at both low and high levels promote growth perfomance of silver carp in both body weight and length. The differenc­es were found to be significant.
