Effect of banana usage as carbohydrate source and binder in practical diet of Black tiger shimp Penaeus monodon

Abstract

The results of banana usage as a source of carbohydrate and natural binder in black tiger shrimp Penaeus monodon diet showed that the replacement of carbohydrate with banana on feeding shrimp could improve shrimpûs growth. Shrimp fed diet containing 3% banana per 12% wheat flour in feed by weight had significantly greater (P<0.05) growth than that of shrimp fed diet containing 0% banana per 15% wheat flour and 6% banana per 9% wheat flour. Whereas there was no significant difference survival rate between shrimp fed diet containing 3% banana per 12% wheat flour and the one which were not fed by banana. But shrimp which were fed by 6% banana and 9% wheat flour had significantly higher survival rate (P<0.05) than those were fed by 6% banana per 9% wheat flour. The result showed that 3% banana could be used in black tiger shrimp diet in stead of the binder replacement, without changing diet quality. Comparing the result of testing shrimpûs diet stability between the diet with 1% binder without banana usage and 3% banana without binder replacement diet, the researchers found no significant different (P>0.05) on average dissolved ammonia of 24 hours immersed diet. There was not any significant difference (P>0.05) on growth and survival rate of shrimp, which were fed by 3% banana with 0% and 1% binder replacement. This study illustrated that the appropriated amount of banana usage in source of carbohydrate and natural binder in shrimp feed could improve shrimp growth, reduce binder usage in shrimp feed and reduce cost of feed production.
