Abstract Commodities African catfish (Clarias sp) is a rapidly growing commodity in Indonesia. Clarias gariepinus is one of the leading commodities and have a good market. African catfish hatchery fish is generally done in areas that have abundant water resources so that a minimal constraint on the area of water. Therefore applied a closed system with the addition of bacteria recirculation degrading organic material that is expected to reduce the accumulation of organic material, there by increasing the survival of African catfish fry. This study aimed to investigate the influence of bacteria that degrade organic material in a closed recirculation system on the survival of fish fry of African catfish (Clarias sp.). This research using Completely Randomized Design with four treatments and five replications of each K treatment (0%), A (1%) (6.0x108 CFU / ml), B (3%) (1.8x109 CFU / ml ) and C (5%) (3.0x109). added bacteria consisting of Pseudomonas pseudomallei with similarity index (97.81%), Pseudomonas stutzeri with similarity index (97.81%), Pseudomonas stutzeri with similarity index ( 61.21%) The results of this study indicate that the addition of Pseudomonas pseudomallei (97.81%), Pseudomonas stutzeri (97.81%) and Pseudomonas stutzeri (61.21%) gave significant differences (p <0.05) against survival of fish fry of African catfish.

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.

The objective of this research was to evaluate the supplementation of turmeric in the diet on antioxidant status and growth performance of African catfish (Clarias gariepinus) in zero water exchange condition. This study used a completely randomized design with 4 treatments and 4 replications. Each treatment consisted of feed supplementation turmeric at dosage of 0; 2.5; 5 or 7.5 g kg-1 diet. One hundred catfish juvenile (5.95±0.05 g) were stocked in intermediate bulk container (IBC) tank (1×1×1 m3) and rearing in zero water exchange condition for 60 days. Catfish were fed at satiation twice a day, in the morning and evening. The results showed that an increase in antioxidant content in catfish fed with the addition of turmeric, which simultaneously also reduced the percentage of liver damage. The parameters of liver damage can be seen from several parameters i.e. pale liver, droplet fat and fat content in the addition of turmeric treatment is lower than without the addition of turmeric. However, catfish fed with the addition of turmeric did not show significant results in terms of growth performances.

A study on the effect of different doses of Ovulin hormone suspended in saline on the breeding performance of Clarias anguillaris and Clarias gariepinus was carried out. The experiment was conducted in a 2x5 factorial experiment in a Completely Randomized Design at the Hatchery Unit of the Department of Fisheries and Aquaculture, Usmanu Danfodiyo University, Sokoto. Species and hormone dilutions constituted the factors with specie having 2 levels (C. anguillaris and C. gariepinus) and Ovulin suspended in saline at 5 levels (0%, 25%, 50%, 75% and 100%). The result showed that species levels did not significantly (P>0.05) affect the breeding performance in all the breeding performance parameters observed. However, fertilization rate, hatching rate and survival rate were significantly affected (P<0.05) by different levels of Ovulin suspended in saline, but did not have significant influence (P>0.05) on egg weight, spawning fecundity and relative fecundity. It could be concluded from this study that Ovulin suspended in saline can have significant influence on the breeding performance of African catfish.
