Indonesian Journal of Tropical Aquatic (IJOTA) is open access publishes papers two times a year in February and Augst. IJOTA will publish the research results useful for the sustainability of fisheries. IJOTA is a scientific journal that discusses the results of research in science, technology, marine and freshwater fisheries that have not been published. Articles should be created in a language that is easily understood by non-specialist readers in the topic of the article itself, but interested in research. This scientific article includes the results of research on Aquaculture (Fish Nutrition, Fish Health and Diseases, Water Quality, Fish Genetics Improvement and Breeding, Fisheries Engineering and Biotechnology), Aquarium Sciences, Aquatic Ecology (Marine, Brackish, Freshwater), Conservation of Aquatic Resources and also Coastal Management. A journal script should be written in English.

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.
