Inclusion of Fresh Raw Material on Tilapia Fry Diets Growth Under Aquaponics System

This research was conducted in a greenhouse in Bajio Experimental Station of INIFAP to study the effects of inclusion of fresh raw material dietary on growth performance, food conversion rate, percentage of weight gained and the survival rate in Nile Tilapia fry. The diets consisted are as follow: 1) 60% commercial feed + 40% live worm; 2) 50% commercial feed + 40% live worm + 10% alfalfa dry leaf; 3) 60% commercial feed + 40% beetle larvae; 4) 60% commercial food + 40% beetle larvae; 5) 100% commercial feed. The fresh raw material levels positively influenced (P > 0.05) the specific growth rate and final weight. The growth parameters studied indicate that diets formulated with ingredients of plant and animal origin were the best diets for tilapia fry during the growth period. These results indicate that the fresh raw material could be incorporated in the diet of Tilapia fry with cost benefit.
