Abstract

Penelitian ini bertujuan untuk mengetahui aspek biologi reproduksi ikan gulamah (Johnius trachycephalus) meliputi rasio kelamin, tingkat kematangan gonad, indeks kematangan gonad, ukuran pertama kali matang gonad, ukuran pertama kali ikan tertangkap, fekunditas dan diameter telur yang didaratkan di TPI Tanjung Beringin Serdang Bedagai. Penelitian ini dilaksanakan pada bulan Juni – Agustus 2022. Sampel ikan gulamah selama penelitian sebanyak 137 ekor yang terdiri dari 65 ekor ikan jantan dan 72 ekor ikan betina. Hasil reproduksi menunjukkan rasio kelamin dalam keadaan seimbang dilihat dari perbandingan ikan jantan dan betina 1:1,09. Ikan gulamah ditemukan pada TKG I-TKG IV. Indeks kematangan gonad jantan 1,109-2,383 dan betina 4,672-7,234. Ukuran pertama kali matang gonad ikan gulamah jantan berukuran 127,596 mm dan betina berukuran 122,727 mm. ukuran pertama kali ikan gulamah jantan tertangkap berukuran 146,690 mm dan betina berukuran 149,720 mm. Fekunditas telur berkisar antara 19.726-110.343 butir, diameter telur berukuran 0,123-0,710 mm. Berdasarkan data diketahui biologi reproduksi ikan gulamah di TPI Tanjung Beringin Serdang Bedagai masih dalam keadaan baik

Abstract

Based on statistical analysis from Dinas Kelautan Perikanan, Deli Serdang Regency in 2018, The capacity for freshwater aquaculture output was recorded at 1328.9 tons / year with a land area of 65.9 ha , which is a problem for the aquaculture community with the decreasing quantity of seed production, limited infrastructure and development management which is still conventional in Desa Perbarakan, Deli Serdang Regency, therefore it is important to implement the required application of science and technology, namely the implementation of semi-natural methods of spawning techniques of koi fish (Cyprinus carpio). Counseling, seminars and practices are the methods of tasks carried out. Extension activities were carried out by illustrating the conceptual awareness of the development of koi fish spawning strategies, the distribution of leaflets, the application of recognition technology, as well as tools and resources, including the dose of gonadotropin hormone (GnH) in broodfish and fish anaesthetic techniques. For female fish, the injected hormone level is 0.5 ml / kg and 0.1 ml / kg for male fish. The weight of the female fish is 1 kg tancho sanke doitsu, 0.5 ml/gr, and the weight of the male fish is 1 kg. At a dose of 0.1 ml / gr and 900 g of shiro, kohaku at a level of 0.09 ml / gr. The result is that the number of eggs is estimated at 10,000, and then the eggs hatch within 2-4 days. Boiled egg yolks are fed to the eggs which hatch into the larvae, then the larvae are transferred to the nursery pon after 10 days of age.
