Abstract

Ikan baung (Hemibagrus nemurus) merupakan salah satu komoditas ikan air tawar ekonomis tinggi di Indonesia. Untuk meningkatkan produktivitas budidaya, maka dilakukan pembentukan generasi baru populasi terbaik agar diperoleh generasi yang lebih produktif dan cepat tumbuh. Tujuan penelitian ini adalah untuk mengevaluasi respons dan pola pertumbuhan benih ikan baung generasi-1 (G-1), generasi-2 (G-2), dan generasi-3 (G-3) pada wadah budidaya yang berbeda. Penelitian dilakukan di kolam semi-permanen, kolam beton dan jaring apung di Instalasi Riset Plasma Nutfah Perikanan Air Tawar, Cijeruk dengan tiga ulangan. Benih yang digunakan berukuran panjang rata-rata 1,54 ± 0,22 cm; dan bobot 0,06 ± 0,01 g; dipelihara dengan padat tebar 50 ekor/m2. Selama 15 hari pertama pemeliharaan benih diberi pakan Tubifex dan pakan komersial dengan kadar protein 41% sebanyak 5% per hari dengan frekuensi pemberian pakan dua kali sehari, untuk pemeliharaan selanjutnya pakan yang diberikan berupa pakan komersil saja. Pemeliharaan dilakukan selama 45 hari, dan pengukuran pertumbuhan dilakukan 15 hari sekali. Parameter yang diamati meliputi laju pertumbuhan spesifik, sintasan, dan pola pertumbuhan. Sebagai data pendukung dilakukan pengukuran kualitas air dan kelimpahan plankton. Hasil penelitian menunjukkan bahwa pertumbuhan bobot dan panjang benih ikan baung G-2 lebih unggul dibanding dengan G-1 dan G-3, sedangkan wadah budidaya yang terbaik adalah pada pemeliharaan di kolam semi-permanen dengan bobot ikan 6,79 ± 4,085 g dan panjang 8,46 ± 1,967 cm. Pertumbuhan ikan baung yang dipelihara di kolam semi-permanen menunjukkan perbedaan yang nyata (P<0,05) terhadap wadah pemeliharan lainnya. Pola pertumbuhan ikan baung dari tiga wadah budidaya bersifat allometrik negatif (b<3).Asian redtail catfish (Hemibagrus nemurus) is one of the high economic value of freshwater fish commodities in Indonesia. In order to increase aquaculture productivity, production of new generation from the best population was conducted to obtain a more productive and fast-growing generation. The purpose of this study was to evaluate the response and growth pattern of G-1, G-2, and G-3 fingerlings of Asian redtail catfish on different rearing media. The study was conducted in semi-permanent ponds, concrete ponds, and floating nets in Research Installation of Freshwater Fisheries Germplasm, Cijeruk with three replications. The stocking density of each treatment was 50/m2, with the fingerlings average length of 1.54 ± 0.22 cm and weight of 0.06 ± 0.01. During the first 15 days, fish were fed with Tubifex and commercial feed (41% crude protein; fed 5% per day) with twice per day of feeding frequency. Fish were reared for 45 days, and growth measurement was conducted by sampling every 15 days. Parameters observed including specific growth rates, survival, and growth patterns. As supporting data, water quality, and plankton abundance were measured. The results showed that weight and length gain on the second generation (G-2) of Asian redtail catfish was superior compared to G-1 and G-3, whilst the best rearing media was found in semi-permanent ponds with the weight of 6.79 ± 4.085 g and the length of 8.46 ± 1.967 cm. The growth pattern of Asian redtail catfish from three rearing media was negative allometric (b<3).
