The effect of locally available low cost ingredients such as silk worm pupae (SWP), soyabean meal (SBM), earth worm meal (EWM) as a replacement of fish meal (FM) on growth, survival and biochemical composition, were investigated for Macrobrachiumdayanum (0.50 g). A significantly higher rate of growth, survival and food conversion ratio(FCR) were recorded for prawns fed EWM, as compared to SWP, SBM, and FM. The proximate composition of flesh further revealed a higher level of proteins and lipids in prawns fed EWM thereby indicating EWM as a possible substitute of FM.
Key words: Macrobrachium dayanum, low cost ingredients, biochemical composition.
