Comparison of the Proximate Composition of Liver and Muscle Tissue Contents in Freshwater and Brackishwater Tilapia, Oreochromis mossambicus

The purpose of the study was to examine the closely related composition of freshwater and brackish fish Oreochromis mossambicus. The fish was brought to the lab and sacrificed for further research. The muscle and liver tissues were processed for moisture, ash, protein, carbohydrate and lipids estimations. The outcomes of the current study showed that the moisture (77.09%), ash (0.78%), protein (195.72mg/gm), lipids (23.07mg/gm) and carbohydrate (15.84mg/gm) content were higher in freshwater fish when compared to brackish water fish. Protein (205.19mg/gm), lipids (3.25mg/gm) and carbohydrate (0.42mg/gm) content were higher in freshwater fish when compared to the liver of brackish water fish. Brackish water fish’s proximate composition in muscle and liver was protein, lipids and carbohydrates are significantly (P<0.05) decreased as compared with freshwater fish. As a result, the chemical composition of fish from brackish water sources has been affected by brackish water ecosystems and, at the same time, the dry matter content, in protein and protein as well as the declared carbohydrate and fat content have been reduced.
