Abstract

The success of spawning is influenced by internal and external factors. One of the factors that affect the var iabi li ty of Pangasianodon hypophthalmus female reproductive is the change of seasons that cause disrupted continuity of the seed availability, especially in the dry season. In the present study, combination of PMSG (pregnant mare serum gonadotropin) + HCG (hormone chorionic gonadotropin) hormone injections was done to induce gonad development. The treatments in this study were without hormone injections as control (A), injection of PMSG 10 IU/kg + HCG 10 IU/kg (B), and injection of PMSG 20 IU/kg HCG + 10 IU/kg (C). Injections were conducted at intervals of two weeks as many as six times. The results showed that gonad maturation generally occurs 2-4 weeks after estradiol-17 peak. PMSG + HCG hormone injections gave a significant effect on increasing the quantity and quality of eggs production. The fecundity in the A, B, C treatments, were 233,700±220,676; 300,305±24,581 and 488,433±142,228; respectively. Number of larvae produced from the A, B, C treatments, were 156,979±170,838; 229,997±18,081 and 362,713±101,850; respectively. Combination of PMSG 20 IU/kg + HCG 10 IU/kg hormone injection gave the best result on fecundity and the number of larvae production.

Abstract

Perkasa pangasiid (Pangasianodon hypophthalmus) is a superior catfish selected by the family that has been released by the Minister of Marine and Fisheries as aquaculture fish which has a selection response of 38.86 %. Genetic quality improvement to accelerate growth can be done through selection activities. The performance test of the Siamese catfish from the selection (Perkasa strain) compared to the non-selection strain (local strain) originating from the farmer. The purpose of this study was to compare the productivity of selection and non-selection Siamese catfish cultivation maintained in a net pond. The initial seeds of the test fish were 3.76 g to 3.79 g with a total length of 2 inches to 3 inches kept in a net pond measuring 3 × 5 × 1.25 m. The water level was around 100 cm with a density of 175 fish/net. Maintenance was carried out for six months. Test parameters observed included: weight gain, specific growth rate, biomass harvest, productivity and cost of production. The results showed that Siamese catfish which were selected for six months of maintenance had a final weight of 698.40 ± 164.54 g and non-selection strains of 595.77 ± 103.41 g. As well as having a higher specific growth rate (3.51 %), higher harvest biomass (11.44 %), and higher productivity (18.71 %) than non-selection Siamese catfish. Based on the bioeconomic analysis, the selection of enlarged Siamese catfish cultivation can reduce production costs up to Rp 390 /kg. The use of Perkasa Pangasiid superior seeds can increase harvest biomass higher than the non-selection seeds.
