Ikan lele sangkuriang merupakan salah satu komoditas nilai ekonomis penting sehingga diperlukan ketersediaan benih yang berkualitas unggul yang ditentukan oleh kematangan gonad betina terutama induk jantan yang telah matang gonad pada pembenihan secara buatan. Faktor terpenting mempercepat kematangan gonad baik betina atau jantan adalah pakan yang diberikan untuk itu diperlukan pakan alternative guna menignkatkan kematangan gonad. Tujuan penelitian untuk memperoleh efektifitas pakan alatnatif guna meningkatkan kematangan gonad yang optimal dari induk jantan. Penelitian ini berlangsung selama 53 hari dengan menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan, perlakuan pakan yang digunakan dalam penelitian ini yaitu perlakuan A: pakan pellet, perlakuan B: pakan keong, perlakuan C: pakan udang, dan perlakuan D: pakan ikan tamban. Parameter utama yang diukur adalah Tingkat Kematangan Gonad (TKG) jantan/Gomatik Somatik Indeks (GSI), dan parameter penunjang adalah pertumbuhan berat, kelangsungan hidup, kesehatan ikan dan kualitas air. Hasil penelitian parameter utama menunjukkan GSI tertinggi adalah perlakuan C yang diberi pakan udang putih yaitu mengalami kenaikan sebesar 0,72%, selanjutnya di ikuti perlakuan D yang diberi pakan ikan tamban sebesar 0.66%, kemudian perlakuan B yang diberi pakan keong sebesar 0.62% dan yang terendah pada pada perlakuan A yang diberi pakan pellet sebesar 0,55 Kualitas air pemeliharaan suhu rata-rata 250 C sd 300 C. pH 6.5 sd 8 dan oksigen terlarut >3 mg/liter sehingga menunjang untuk tumbuh dan berkembangnya ikan uji.

Channa striata is a fishery commodity that has high economic value. However, the availability of cork fish is very dependent on the availability of nature due to the lack of technology in the provision of seeds in a sustainable manner. In general, semi-artificial spawning with hormone induction is done for parent efficiency as well as increasing the quality and quantity of fish eggs as potential fish seeds. One of the spawning hormones that can be used is Pregnant Mare Serum Gonadotropin (PMSG), this hormone contains many elements folicle stimulating hormon (FSH) which can trigger gonad maturation in the early stages of oocyte formation and egg yolk filling in the process of vitelogenesis which will have an impact on egg diameter and fecundity. The purpose of this study is to determine the optimal dose of the PMSG hormone to increase egg quality in this case is the diameter of the egg and the quantity of eggs in this case is fecundity. The female cork fish used has a size range of 30-40 cm with a weight of 500 - 700 g, adapted in a controlled container then PMSG hormone induced by treatment A dose: 0.75 mL / kg; B: 1.0 mL / kg; C: 1.25 mL / kg; D: 1.5 mL / kg and repeated three times. Then wait up to 72 hours to find out the development of oocytes. The results showed that the best treatment for egg diameter with a dose of 1.25 mL / kg with an egg size of 1.04 mm, whereas in fecundity with a hormone dose of 1.5 mL / kg produced 23,612 eggs.

Channa striata is the one of the local comodity in West Kalimantan Province which has important economic value. The demand for Channa striata comes mostly from urban communities, while urban areas only have narrow land / yard. One of the techniques of fish cultivation in narrow land is the aquaponics system. Thus, Channa striata cultivation with the aquaponics system can increase the productivity of cork fish in urban areas. The purpose of this study was to obtain the optimal amount of stocking density in Channa striata culture with an aquaponics system with indicators of success namely survival and growth rate. This study lasted for 75 days, taking place at the Pontianak City Fish Agribusiness Farm. The study design used a Completely Randomized Design (CRD) with 4 treatments and 3 repetitions, The stocking solid treatment used in this study is A: 40, B: 60, C: 70, and D: 50 tails / m2. The results showed that treatment A had a significant effect on the absolute growth rate of 12.85 gr followed by perlkuan D: 12.46 gr, B: 8.87 gr, C: 7.9 gr, while the best specific growth rate was needed at time A: 3.50%, D: 3.44%, B: 3.05%, C: 2.91%. The observation of life survival also has the same trend, namely the best treatment in treatment A: 95%, D: 90%, B: 70%, C: 49%. From the results of these studies it can be concluded that the higher the stocking density in aquaponics fish farming systems will have an impact on the growth rate and the survival rate of Channa striata with the best treatment, namely with stocking density of 40 fish / m2.
