Nile Tilapia Oreochromis Niloticus

Aquaculture is composed of various themes of interest, particularly does eutrophization due to feeding have direct effects on fish ponds and the whole aquatic system. This study focused on the study of the water quality of an aquatic system related to Nile tilapia (Oreochromis niloticus) rearing. Sampling was done at six sites during one rearing cycle (six months), taking water from the source of water supply, the fish pond itself, the effluent of the fish pond and the mixed waters. A principal component analysis revealed that, among all the environmental variables analyzed, chlorophyll-a, total nitrogen and phosphorus and organic matter were responsible for the variations observed during the rearing cycle. Other sources of variability extrinsic to the fish pond make it evident that the assessment must take the entire aquatic system related to the rearing into consideration, minimizing negative effects.
