Abstract

This research aimed to know the effect of addition different dose of traditional ingredient in feed of African catfish on the growth, survival rate and food conversion ratio. The experiment used completely randomized design (CRD) with four treatment and triplicates, the treatment wear dose of traditional ingredient which were 0 cc, 5 cc, 10 cc and 15 cc each kg food. The research was conducted in Laboratorium of Fisheries Research, Faculty of Agriculture, Gadjah Mada University.

Traditional ingredient was mixed in food at the time of feeding. The African catfish were fed add-satiation. Parameter measured were: growth, survival rate, food conversion ratio and size variation of harvest. The result of the experiment showed that the addition of traditional ingredient did not influenced significantly on lenght, weight, specific growth, survival rate and food convertion ratio. The proportional of food conversion ratio value got smaller when the addition of traditional ingredient going up. Key words: African catfish, growth, and traditional ingredient.
