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.

Abstract

Pangasius is a freshwater fish included in the main commodity by the Ministry of Marine Affairs and Fisheries, Indonesia. Siamese catfish production ranked 4th in freshwater fish commodities in 2016 after goldfish, tilapia, and catfish. Pangasius has a lack of EPA (Eicosapentaenoic acid) and DHA (Docosahexaenoic acid) if compared with fish from the sea. Application of additional different levels of soybean oil in commercial fish fed to enhance EPA (Eicosapentaenoic acid) and DHA (Docosahexaenoic acid) in Perkasa pangasiid flesh. This study was conducted to determine the effect of adding soybean oil with different levels of commercial fish feed given to Perkasa striped catfish on growth performance, feed efficiency, EPA (Eicosapentaenoic acid), and DHA (Docosahexaenoic acid). This experimental study used a Complete Randomized Design (CDR) with triplicates and five treatments with additional levels of soybean oil in commercial fish fed: (a) 0%, (b) 2%, (c) 4%, (d) 6%, and (e) 8%. The result showed that treatment of (e) is the best treatment for increasing the EPA (Eicosapentaenoic acid) and DHA (Docosahexaenoic acid) in Pangasius flesh. However, additional different levels of soybean oil in the commercial fish feed have no negative effect on growth performance and feed efficiency in Perkasa pangasiid.

Abstract

Konten DNA inti (KDI) suatu spesies atau populasi terbentuk melalui berbagai mekanisme seperti mutasi kromosom, insersi dan delesi, transposable element, dan duplikasi. Selain itu, hibridisasi dan posisi spesies dalam filogeni juga berperan mempengaruhi keragaman KDI. Penelitian in bertujuan menginvestigasi profil KDI pada empat spesies ikan patin dari genus Pangsius yang meliputi Pangasionodon hypophthalmus, Pangasius djambal, Pangasius nasusutus, Pangasius nieuwenhuisii, hibrida P. hypophthalmus betina dan P. djambal jantan (Hibrida HD), dan hibrida P. hypophthalmus betina and P. nasutus jantan (Hibrida HN). Sel darah merah diambil dari masing-masing spesies dan pengukuran KDI dilakukan menggunakan Attune Acoustics Flow cyometer (ABI), dengan pewarna DAPI dan sel darah merah ayam, Gallus domesticus, sebagai kontrol standar. Hasil penelitian menunjukkan rerata KDI P. hypophthalmus, P. djambal. P. nasusutus, P. nieuwenhuisii, adalah 0.960±0.0254 pg, 1.017±0.0510 pg, 1.000±0.0410 pg, 1.074±0.0231 pg, berada dalam kisaran KDI famili catfish lainnya. KDI Hibrida HD dan Hibrida HN masing-masing 005±0.0358 and 0.956± 0.0089. Diantara species tetua, KDI terendah terdapat pada P. hypophthalmus dan berdeda nyata (P<0.05) dengan KDI P. djambal dan P. nieuwenhuisii tetapi tidak berbeda (P>0.05) dengan P. nasutus. KDI Hibrida HD dan Hibrida HN tidak berbeda dengan masing-masing tetuanya. Namun, pola KDI kedua hibrida berbeda dimana Hibrida HD berada diantara kedua tetuanya sedangkan Hibrida HN berada di bawah kedua tetuanya. Secara filogenetik, keragaman KDI pada genus Pangasius tidak mengikuti pola kekerabatan sesuai hubungan filogenetik berdasarkan marka genetik sitoplasmik dan inti. Kata kunci: Flow cytometry, konten DNA inti, P.hypophthalmus, P. djambal, P. nasutus, P. nieuwenhuisii, hibrida.
