Abstract
The effects of the yeast, Phaffia rhodozyme in the diet on growth, body composition, muscle elasticity and pigmentation of Israeli strain of common carp, colored carp and Nile tilapia were investigated. Ten percent of the yeast was added to semi purified diet as an experimental feed 1. Ten percent of brewers yeast in the semi purified diet (experimental feed 2) was tested for comparing the growth performance between two semi purified diets. A commercial diet was also used for the check of growth rate of the semi purified diets. All experimental fish were fed for 10 weeks. The weight gains among the experimental fish were not significantly different (P>0.05). There were not significantly different in body composition, muscle elasticity among the the fishes fed three experimental diets. There were significant differences (P<0.05) of pigment deposition in the muscle of Israeli strain of common can and on the skin of colored carp between treated and non treated group. But there were no differences of pigment deposition in flesh and skin of tilapia among the three diets.
