Elaboration and Physicochemical Characterization of Phytonutrients for Tilapia Nilotica (Oreochromis niloticus)

Fedol Amel, Cheriti Abedelkrim1 and Belboukhari Nasser

Alvins of Oreochromis niloticus (1.2 ± 0.04 g) were fed with four test diets. (F1, F2 and F3) formulated using vegetable proteins derived primarily from agricultural by-products and crop residues. The fourth formula contains animal protein in addition to agricultural by-product. After 120 days of experience fry are fed with another test diets (F) with the percentages of protein satisfied Tilapia requirements. The results show that among the forms prepared formula (F4) protein-based animal and plant has a better growth rate and the second nutrient (F) balanced greatly reduce the time`s farm.
