Abstract Currently, African catfish is developing quite rapidly, because African catfish is one of the important commodities in the fishery. Efforts to increase the production of African catfish is to improve the quality of feed. The purpose of this study was to determine the effect of the use of shark waste mill on the growth rate, feed efficiency and survival rate of African catfish fishing. The research method was experimental with completely randomized design (CRD). The research consisted of five treatments and four replications. The treatments used were: (A) shark waste mill at 0% and fish mill by 50%, (B) 5% shark waste mill and 45% fish mill, (C) 10% waste shark mill and 40% fish mill, (D) 15% waste shark mill and fish mill and 35% (E) 20% shark waste mill and 30% fish mill. The main parameters measured were growth, feed efficiency and survival rate. Supporting parameters measured were water quality. Analysis of the data using analysis of variance (ANOVA) and to determine the differences between treatments tested by Duncan Multiple Range Test. The results showed that the giving of shark waste mil on ration had highly different effects on growth rate and feed eficiency of african catfish. The feeding of waste shark mill in ration had no significantly different effect on Survival Rate (SR). The best dose of shark waste mill is treatment C (10%) with growth rate (1,26%/day), feed eficiency (38,64%) and survival rate (55%).

Critical factor for successful fish farming is feed. Feed should always be available and in accordance with the needs of farmed fish both in quality and quantity. Black nile tilapia are reared intensively, requires diet crumb size with protein content is not less than 30%. Diet made by the composition and nutritional value in accordance with the age of the fish. The purpose of this study was to find the optimum percentage of leaf meal turi in artificial feed on the growth of black nile tilapia’s weight about 6 g/fish. The treatment in this study was the addition of turi leaf flour in artificial feed at 0%, 3%, 6%, 9% and 12%. Fish stocking density is maintained with 1 fish/L water for 40 days in a plastic tub volume of 15 liters and given the aerator. Measurement the amount of feed consumed was calculated to determine the feed efficiency. Data were analyzed using ANOVA and then the differences between treatments were tested using Duncan's Multiple Range Test. The results showed the highest of daily specific growth rate and feed efficiency obtained in the treatment of feed containing turi leaf flour of 0-9% were respectively 1.66 to 1.57% and from 45.57 to 39.82%. Keywords : Black nile tilapia; Daily specific growth rate; Feed efficiency; Turi leaf flour
