Studies on the Influence of Artificial Fish Feed on the Growth of the Fingerlings of the Spotted Tilapia, Pelmatolapia mariae

Abstract

Background and Objective: Aquaculture is a widely practised agricultural method globally, which involves raising aquatic organisms in suitable environmental conditions. Its main objective is to meet the increasing demand for fish and reduce reliance on fish imports and fishery products. Materials and Methods:In the present study, spotted tilapia, Pelmatolapia mariae, obtained from the local market were fed with artificial diets, namely Diet 1, Diet 2, Diet 3, Diet 4 and Diet 5. Over a period of 28 days, the live weight, standard length, total length and biochemical composition (protein, carbohydrate and lipid) of the fish were monitored every 7 days. Results: After the 28 days period, the control group exhibited higher total length and standard length, while Diet 5 resulted in a higher live weight. Fish fed with Diet 5 also showed a higher protein content. Carbohydrate content was found to be higher in fish fed with Diet 3 and the control group. On the other hand, the control group had a higher lipid content. Conclusion: Considering the superior growth and biochemical constituents observed in fish fed with Diet 5, it is recommended to incorporate chicken wastes such as legs and intestines, as well as agricultural byproducts like cauliflower leaves and moringa, into artificial fish feed. This can potentially enhance the overall performance and productivity of aquaculture systems.
