Abstract
Three experiments were performed to determine the effect of using two levels of palm pollen grains, yeast and moringa leaves beside control (without) on reproductive performance of broodstock and growth performance of their fries at commercial hatchery (trials one and two) and fish farm of faculty of Agriculture, Fayoum University. The results revealed that spawned female number/collection, egg number/fish/ collection, fry number/fish/ collection, spawning number/fish/trial period and feed conversion ratio as amount of feed required to produce 1000 fry were improved significantly (P<0.05) with palm pollen grains or yeast addition. The highest values were obtained with 2.0 % palm pollen grains or yeast levels followed by 1.0 % and 0.0% levels, respectively. But moringa leaves affected by decreasing fry growth performance with increasing levels of supplementation and the control diets was the best.
It could be suggest the use of 2.0 % palm pollen grains or yeast levels in tilapia broodstock diets for better reproductive performance.
