CASE STUDIES SUSTAINABLE FISH PELLETS DESCRIPTION: The study focused on the development of a newly formulated fish feed pellet using household waste and its impact on water quality. The feed pellets are prepared through an extrusion method, incorporating ingredients such as fish waste, sugarcane fibre waste, chicken fats, and used palm oil. The study aimed to evaluate the effectiveness of these pellets in preserving water quality compared to commercial fish feed. RESULTS: The formulated fish feed pellets demonstrated positive outcomes in maintaining water quality. The composition ratios for pellet production ranged from 50% to 100% fish waste. Observations showed that compositions with 70% to 100% fish waste had a well-built structure without any crumble formation. Turbidity tests revealed that after three hours, formulations ranging from 50% to 70% exhibited low turbidity values below 5.00 NTU, while commercial fish feed and 80% to 100% formulations had higher turbidity levels. pH testing showed that commercial fish feed and 100% formulation had slightly alkaline values, while other compositions exhibited acidic properties due to the leaching of natural ingredients. BOD analysis indicated that the 60% formulation resulted in the highest depletion of dissolved oxygen, suggesting a higher amount of organic matter available for bacterial activity. CONCLUSION: The study concludes that the newly formulated fish feed pellets, utilising household waste, offer improved water quality preservation compared to commercial fish feed. The composition of 60% fish waste demonstrated the best combination, showing low turbidity and BOD levels. These results highlight the potential for further optimisation of fish feed pellet production and large-scale implementation to enhance sustainable aquaculture practices. By utilising natural ingredients and adhering to Shariah compliance, the environmental impact of fish farming can be minimised, contributing to the preservation of water resources and aquatic ecosystems. 52 GREEN PRACTICES GUIDELINE FOR FISHERIES SECTOR (AQUACULTURE)
