Utilization of fish waste as fish feed material as an alternative effort to reduce and use waste

Abstract

Background and Objective: Waste of fish catching and waste of fish fillet processing will cause environmental pollution, but these materials can still be used as raw material for fish feed. The objective of this research was to change fish wastes to be made as fish powder as raw material of fish feed. Materials and Methods: This research employed a completely randomized design with three treatments; Treatment A is artificial feed that uses raw material from trash fish, Treatment B is artificial feed that uses raw material from fish fillet waste and as control is factory-made feed. The silver pompano fish stocking was done with stocking density of 20 fishes mG3. The fishes were cultured for 60 days and they were adapted with formulated feed during 7 days before testing. Results: Fish powder material in Treatment A coming from trash fish waste had good enough protein content by 43.84%, while fish powder material in Treatment B coming from fish fillet waste had lower protein content by 36.3%. The results showed that the control produced better growth activity indicators compared to Treatment A and B. The results of economic analysis showed that Treatment A and B were cheaper to produce compared to control. Conclusion: Fisheries waste both fish catch and fish fillet waste can be used as raw material for making silver pompano fish feed. Utilization of the two wastes has two functions namely saving on aquaculture costs and reducing fisheries waste.
