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.

This study aims to determine the effect of artificial feed by adding cassava leaf flour (Manihot utillisima) to the water quality of the African catfish nursery pond (Clarias gariepinus). This study used the T test (one sample T test) to compare the treatment with artificial feed and commercial feed consisting of 3 replications. The feeding dose was 3% of the weight of the fish for 30 days of maintenance with the frequency of feeding twice a day. Parameters observed were NH3, NO2, NO3, pH, temperature, DO and survival of African catfish. The results showed that the provision of artificial feed in the African catfish nursery did not have a significant effect (P> 0.05) on the observed water quality parameters. The quality of water obtained during maintenance by providing commercial and artificial feed is still supporting the survival of African catfish.

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.

Pituitary Homogenate

The results of reproduction were tested in females of the African catfish (Clarias gariepinus Burchell 1822) after stimulation of ovulation with carp pituitary (4 mg/kg body weight) or with Lecirelin (15 &mu;g/kg) and metoclopramide (10 mg/kg). After administering the synthetic substance eggs were obtained from all females while in the group treated with pituitary homogenate 7 out of 8 hypophysed females spawned. The applied spawning agent did not significantly influence the weight of eggs expressed in grams, but in the case of females treated with carp pituitary homogenate a significantly higher weight of eggs expressed as the percentage of body weight of fish was recorded. The applied stimulators of ovulation did not affect any trait reflecting the quality of eggs. Females used as an experimental material belonged to two categories in respect of body weight: lighter females with average body weight of 2.63 &plusmn; 0.36 kg and heavier females with average body weight of 3.91 &plusmn; 0.48 kg. It was proved that the weight of eggs expressed either in grams or as a percentage of a female&rsquo;s weight was significantly related to the body weight of a female (P &le; 0.01 and P &le; 0.05, respectively), as well as the percentage of fertilised eggs and the percentage of living embryos after 28 hours of incubation (P &le; 0.05 and P &le; 0.05, respectively). The interaction between the stimulator of ovulation and the female body weight was significant only for traits reflecting the weight of obtained eggs (P &le; 0.05 and P &le; 0.01). &nbsp;

Ortho-phosphate inside recirculation aquaculture systems is limited as a consequence of precipitation and regular water exchange rates. To improve plant growth in coupled aquaponics, phosphate fertilizer addition to hydroponics can increase PO43−-P concentrations inside the process water. We investigated the effects of four PO43−-P concentrations (<10 (P0), 40, 80, 120 mg L−1) in rearing water on growth performance, feed efficiency, and welfare traits of juvenile African catfish (Clarias gariepinus Burchell, 1822). By trend, optimum specific growth rate of 2.66% d−1 and feed conversion ratio of 0.71 were observed at 40 and 80 mg L−1 PO43−-P. Higher PO43−-P significantly affected skin coloration, swimming activity and external injuries, with the palest and inactive fish combined with most external injuries in the P120 group. Mineral and protein contents in the fish remained unaffected, while fat content inside the fillets enriched with increasing PO43−-P. Inorganic P in blood plasma increased significantly, while phosphate concentrations inside the fillet remained unchanged. We suggest that PO43−-P concentrations of 40 to 80 mg L−1 do not reduce the performance of African catfish aquaculture, while increased values of 120 mg L−1 affect fish welfare. This allows limited addition of PO43−-P fertilizer in coupled aquaponics with African catfish to support plant growth.
