Effect of freshwater fish oil feed supplementation on the reproductive condition and production parameters of hybrid catfish (Pangasius larnaudii x Pangasianodon hypophthalmus, Sauvage, 1878) broodstock

AbstrakIkan patin siam (Pangasianodon hypophthalmus) merupakan komoditi ikan air tawar asal Thailand yang berkembang pesat di Indonesia. Permintaan ikan patin yang cukup tinggi menuntut ketersediaan benih yang terus berkelanjutan, sehingga perlu dilakukan upaya untuk meningkatkan stok benih di pasaran melalui pengembangan teknik pembenihan. Teknik pembenihan adalah suatu tahapan kegiatan dalam budidaya bertujuan untuk menghasilkan benih dan sangat menentukan tahap kegiatan selanjutnya, yaitu pembesaran atau pemeliharaan. Pemberian tanah liat diharapkan dapat meningkatkan keberhasilan pemijahan ikan patin siam karena tanah liat mampu mencegah telur ikan patin saing menempel. Percobaan ini menggunakan pemijahan buatan dengan penyuntikan hormon HCG dan ovaprim dan penggunaan tanah liat. Percobaan pembenihan ikan patin siam dilaksanakan pada bulan Juli sampai September 2016 di Balai Penelitian Pemuliaan Ikan (BPPI) Sukamandi, Subang, Jawa Barat. Di akhir percobaan ini diperoleh hasil laju fertilisasi 78,93% dan laju penetasan sebanyak 84%, sedangkan laju fertilisasi pada kontrol lebih rendah dibawah perlakuan yaitu 70,19% sedangkan untuk laju penetasan sebanyak 70,09% AbstractPatin Siam (Pangasianodon hypophthalmus) is a commodity of freshwater fish from Thailand originally which is growing rapidly in Indonesia. The high demand for the patin siam needs the availability of seeds to increase seed stock in the market through hatchery. The hatchery is an activity in cultivation that that aims to produce seeds. The provision of clay is expected to increase the success of spawning of Siamese catfish. This experiment uses artificial spawning with HCG and ovaprim hormone injections. Experiments of Siamese catfish hatchery were carried out from July to September 2016 at the Sukamandi Fish Breeding Research Institute (BPPI), Subang, West Java. At the end of this study resulted in 78,93% in Fertilization Rate and 84% in Hatching Rate while in control 70,19% in Fertilization Rate and 70,09% in Hatching Rate.

The nutrient profile of five freshwater fish species viz., Mystus vittatus, Ompok bimaculatus, Channa striata, Wallago attu and Pangasianodon hypophthalmus were studied. The proximate composition data shows that the moisture and fat content differed significantly (P<0.01) among the fish species. The fat content was significantly higher in P. hypophthalmus and M. vittatus. The moisture was significantly higher in C. striata. The potassium content was significantly (p<0.01) higher in C.striata. M.vittatus shows higher content of calcium. The other trace minerals like iron, copper and zinc contents of fish did not differ significantly among the species. The vitamin A content is maximum in O.bimaculatus whereas vitamin D content is higher in Mystus vittatus. The palmitic acid was significantly (p<0.01) higher in M. vittatus. The oleic acid was significantly (p<0.01) higher in C. striata and W. attu. The linoleic acid content was significantly (p<0.05) higher in P. hypophthalmus. One of the important PUFA i.e. DHA was significantly higher in O. bimaculatus and C.striata. The PUFA content was significantly (p<0.05) higher in O.bimaculatus and P.hypophthalmus. Among the amino acids, arginine, histidine, threonine and isoleucine were higher in P.hypophthalmus. C.striata and W. attu contain high amount of Tryptophan. Glutamic acid was high in O.bimaculatus and Aspartic acid was high in C. striata. The energy content was maximum in P. hypophthalmus. The nutrient profile of these fish species revealed that they were rich in all the essential nutrients required by human being. The information on nutrient profile of fish will give a guideline to dieticians, nutritionists, medical practitioners, researchers to advice consumers to take fish in their daily diet as a health food.
