Abstract

Abstract Rearing of African catfish fry requires an abundant water supply, so this causes Clarias gariepinus hatchery operations difficult in areas that lack water, so use a closed recirculation system technology which is an attempt to tackle the problem of limited water in an area for hatchery operations. However, these systems have drawbacks which deposition of organic materials on water quality pond maintenance reduced the need for water quality management. Components of organic materials is a source of water quality pollutants consisting of proteins, lekam, and carbohydrates, so that in the organic material needed pendegradasian existence of groups of bacteria and proteolytic bacteria, lipolytic, and amylolitic. The results of this study show that in the media of African catfish hatchery fish have bacteria that degrade organic material that has properties of proteolytic, lipolytic, and most potentially amylolitic consisting of bacterial isolates of Pseudomonas stutzeri B ie (97.81%) with values highest protease hydrolysis test results 1.878 mm, ie G isolates of Pseudomonas pseudomallei (97.81%) with the highest value of 1.909 mm hydrolysis test and bacterial isolates of Pseudomonas stutzeri K (61.21%) with the highest value of 1.944 mm hydrolysis test.

Abstract

Abstract The growth of betutu classified slow, so do efforts in order that growth of betutu which protected optimal by choosing the exact food combination. This research is purpose to know the growth fingerlings of betutu. This research using complete random program giving 3 repeated by the way of treating P1 (food 100% pelet), P2 (food 100% Daphnia spp.), P3 (food 100% Tubifex sp.), P4 (food 100% Anadara granosa), P5 (food combination 50% pelet and 50% Daphnia spp.), P6 (food combination 50% pelet and 50% Tubifex sp.), P7 (food combination 50% Anadara granosa and 50% Daphnia spp.), P8 (food combination 50% Anadara granosa and 50% Tubifex sp.). Main test parameter checked on this research is growth (accretion weight), growth rate, specific growth rate, and absolute body length growth, while supporting test parameter is water quality. Data of growth analysis using ANAVA (varian analysis) and if there is the influence the way of treating so continued with Test of Multiple Gap Duncan by trusty degree 95%. The result of research show the growth (accretion weight), growth rate, specific growth rate and the best absolute body length growth on the way of treating P6 which not different with the way of treating P3 and P8.
