Abstract

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

Abstract

Abstract When small giant gouramy fry, 40 to 80 days old can consume carbohydrate diet, starch but his growth slow. Conversely, when he consumes simple carbohydrate, his growth is faster. Considering that feedstuffs derive from plants containning much complex carbohydrates like starch that is easier obtained and relatively cheaper price, so, it is important to study utilization of the starch as feedstuff on the diet of the giant gouramy fry. This research was carried out to find out type of carbohydrate that is suitable for giant gouramy fry above 80 days old. For achieving this purpose, it was important to test utilization of the diet containing starch compared with diet containing glucose, sucrose and dextrin on the growth of the giant gouramy fry. The giant gouramy fry was fed diet containing 27.68 % of glucose, sucrose, dextrin and starch each. The Feedstuffs in the diet were composed isocalorie and isoprotein. The giant gouramy fry that tested was 130 days old and average weight 6.90 grams. The fishes were cultured with stocking rate 5 fishes per 60 litre of water and cultured for 60 days. The diet that contains starch resulted the same on daily average growth rate to compare glucose, sucrose and dextrin ( P > 0.05 ). Sucrose diet resulted protein retention, lipid retention and energy retention higher than starch diet ( P < 0.01 ). Starch diet resulted the lowest retention of protein, lipid and energi ( P < 0.01 ). It was concluded that the sucrose was the best carbohydrate source for the giant gouramy fry, 130 to 190 days old. The starch was not suitable yet as source of carbohydrate to compose diet of the giant gouramy fry, 130 to 190 days old or average weigh 6.90 to 16.50 gram.

Abstract

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%).

Abstract

Abstract Artemia is an important live feed in the hatchery. Quality of Artemia can not be separated from the feed quality that given. The quality and quantity of feed in the waters constitute factors that determine the growth rate and nutrition contentent the Artemia. This study aims to determine effect of different live feed type to the growth rate and nutritional content on Artemia sp.. The research method used was experimental with Completely Randomized Design (CRD) using four treatments and five replications. The treatments used were: silage fish (A), Skeletonema sp. (B), Chaetoceros sp. (C) and Tetraselmis sp. (D). Analysis of data uses Anova. To know the difference among the treatments were done by Duncan Multiple range test. The results showed that difference of natural feed influence highly significant (p<0,05) on the rate of growth in absolute length and significant influence (p <0,05) on average daily growth weight of Artemia sp. Absolute length growth rate was highest in treatment D (3,92mm), then a row followed by treatment C (3,275mm), A (1,89mm) and B (1,775mm). The daily growth rate of weight was highest in treatment D (25,43%), then a row followed by treatment C (21,91%), B (19,24%) and A (18,77%). . Artemia that given live feed produces highest nutritional value of D (protein 44,96%; carbohydrate 18,47% and fat 26,91%) wasted Tetraselmis sp. and the lowest obtained by treatment A (protein 41,21%; carbohydrate 8,88% and fat 29,1%) wasted silage fish. Water quality during Artemia cultivation was temperature 28-320C, pH 7, dissolved oxygen 5-8 mg/L, salinity 31 ppt and ammonia 00,25 mg/L.
