Enrichment of tilapia (Oreochromis sp.) artificial feed with banana powder in an integrated culture system

Abstract

The experiment were conducted for 50 days usmg integrated culture between Tilapia, Oreochromis sp. and lettuce, Lactuca saliva L. in closed water recirculation system. This study was held to access the enrichment of Tilapia artificial feed with banana powder in an integrated tilapia-lettuce production system. Banana powder was selected as feed additive which was widely found and available around Malaysia and famous product from food processing industries. Treatment feed 1 was control feed, treatment feed 2 consist 10% banana powder, treatment feed 3 consist of 20% banana powder and treatment feed 4 consist 20% banana powder. For treatment 4 which powder of banana skin was replaced with banana powder (T4). The proximate analyses were done to access the nutrition content of banana powder, banana powder skin, treatment diet and fish tissue at the end of the experiment (feeding protocol). The total yields of the fish and lettuce were measured. From the results, addition of 10% of banana powder (T2) significantly increased the SGR of tilapia.
