Lipid profile and metabolic parameters of tilapia in the finishing phase in earth ponds or using biofloc technology

Tilapia is a species with great growth potential. Its production comes from semi-intensive system, such as earthen ponds (EP). Recently, biofloc technology (BFT) appears an option to intensify fish production. The objective of this work was compare the organosomatic indices, biochemical parameters, and chemical composition tilapia reared in EP BFT. Fish were grown for 150 days, initial weight ≅ 2 g final 780 g. Thereafter, tissues organs collected determine indices analyze fatty acid, proximate composition. carcass yield higher than system did not affect fillet yield. other parameters showed content crude protein lipids fillet. In both systems, there no difference body lipid profile. BFT concentration glucose ammonia muscle amino acids liver. lactate liver compared those conclusion, alters metabolism fish. has considerable amount acids, which can be considered formulation diets system.
