In order to the success of domestication programs of Asian redtail catfish is necessary to evaluate the level of change in each generation produced. This study aimed to evaluate the performance of growth and survival rate on three populations from each generation spawned of Asian redtail catfish (G-1, G-2 and G-3). The study was conducted experimentally used completely randomized design (CRD) with 3 treatments and 3 replications from May to July 2017. The origin of the post larvae of Asian redtail catfish was the modified seeds from mass spawning of Asian redtail catfish of Cirata population. G-1 was the population resulted from the spawning of the oldest broodstock, G-2 was a population resulted from spawning of the first generation broodstock and G-3 was the resulted from spawning of the second generation broodstock. Spawning process was conducted in the same time. The age of the seeds was one week old after hatching with total length of 0.8-1.0 cm and body weight of 0.0082 ± 0.0001 g. The Asian redtail catfish seeds were reared in the aquarium with dimension of 70 cm 50 cm x 40 cm and equipped with recirculation system. Each aquarium was stocked seed with a density of 2,000 individual 100 L-1 of water. During rearing process (15 days), fish were fed at satiation with frequency of three times per day. Feed was adjusted to mouth opening of larvae. Initially, larvae on 1 to 7 days of rearing process were fed with artemia and after that fed with tubifex. The result showed that the highest growth and survival rate performance (P<0.05) were obtained in Asian redtail catfish seed (G-3) with a value of 1.64 ± 0.02 cm and 53.42 ± 8.86%, respectively. Postlarvae of Asian redtail catfish from third generaton of domesticated (G-3) can increase fish productivity.

Domestication is one of the important steps in culturing wild fish into a captive system. This study aimed to evaluate the growth, survival rate, and feed efficiency of three generations (G-1, G-2, and G-3) of domesticated Asian redtail catfish. This study was conducted in the wet laboratory of Research Institute for Freshwater Aquaculture and Fisheries Extension (RIFAFE) Bogor from October to December 2017. The Completely Randomized Experimental Design with three treatments and three replications were utilized in this study. Experimental fish were obtained from mass spawning on three generations of Asian redtail catfish Cirata population. The size of experimental fish ranged between 2-3 cm of length with average weight was 0.32 ± 0.01 g. Fish were maintained in the aquarium (dimension = 70 cm x 50 cm x 40 cm) equipped with recirculation system. The circulation system was equipped with filters (rocks and sands). Each aquarium was stocked with a density of 30 individual 100 L−1. During 40 days of rearing, fish were fed with 10% day−1 of tubifex worms from the total fish biomass. Feeding was carried out three times a day at 07.00 AM, 12.00 PM, and 17.00 PM. The result showed that Asian redtail catfish seedlings from second and third-generation (G-2 and G-3) had significantly different growth performance (P<0.05) compared to first-generation (G-1), with the length gain of 5.57 cm and 5.57 cm, weight gain of 7.98 g and 7.99 g, specific growth rate on length of 2.97 % day−1 and 3.02 % day−1, specific growth rate on weight of 8.18 % day−1 and 8.22% day−1, and survival rate of 82.11% and 84.22%. The biomass value of three generations on Asian redtail catfish did not show any significant differences (P>0.05), while the best FCR and feed efficiency value (P<0.05) were found on Asian redtail catfish from third-generation (G-3) with a value of 73.00 ± 2.24% and 1.37 ± 0.04.
