Effect of Incorporation Different LIPIDOL levels on Growth Performance and Chemical Composition ofOreochromis niloticusfry.(Linnaeus 1758)

Abstract

This study was carried out to evaluate the effect of LIPIDOL on feed of experimental fish. On growth rate ,food conversion efficiency and water characteristic of O. niloticus fingerlings . The study was done at the university of Sudan kuku experimental from of department of fisheries sciences and wildlife. The study was carried out in the 8 experimental plastic aquarium each stoked with 20 fish,Aeration was provided by air pump for each aquarium. These types of feed together with accounted were formulated using 1% ,2.5% and 4% lipidol fish were fed 10% of their body weight divided into three times a day for four weak. Then it was reduced to 7% of the body weight for the rest of the experiment. Data were statistically analyzed using ANOVA one away analysis.Results showed that fish fed 4% lipidol had the highest final weight .and fish fed 1% lipidol had the lowest final weight. Key words:lipidol,growth, body weight , O. niloticus, water characteristic.
