Abstract

TULUS ROMORA SITUMEANG. Pembenihan dan Pembesaran Ikan Kakap Putih Lates calcarifer di PT. Bali Barramundi, Buleleng, Bali (Hatchery and Grow- out of Barramundi Lates calcarifer at PT. Bali Barramundi, Buleleng, Bali). Dibimbing oleh ANDRI ISKANDAR.

Ikan kakap putih Lates calcarifer merupakan komoditas ikan air laut yang memiliki keunggulan yakni nilai permintaan pasar yang tinggi dengan kandungan nutrisi yang baik. Kegiatan pembenihan terdiri dari persiapan wadah, pemeliharaan induk dengan padat tebar 1–3 ekor/m3, pemijahan induk, pemeliharaan larva, pemeliharaan benih, pemanenan dan pasca panen. Induk ikan kakap putih melakukan pemijahan dan menghasilkan telur yang terkumpul pada egg collector, kemudian telur ditebar ke dalam wadah penetasan telur. Pemeliharaan larva dilakukan ketika larva menetas hingga berumur D16. Pada kegiatan penetasan telur didapatkan fertilization rate 56%, hatching rate 62% dan survival rate 45% dengan padat tebar 20-30 butir telur/L. Analisa usaha pembenihan memperoleh keuntungan sebesar Rp 1.025.332.465/tahun dengan R/C ratio 1,7. Kegiatan pembesaran ikan kakap putih terdiri dari persiapan wadah pada kja, penebaran benih, pemberian pakan, pemanenan dan pascapanen. Nener berukuran 10-12 cm dapat dilakukan penebaran dengan kepadatan 45-50 ekor/m3 dan dipelihara pada KJA (Keramba Jaring Apung) selama 6 bulan hingga mencapai ukuran 1000 g/ekor. Kegiatan pembesaran memperoleh keuntungan sebesar Rp 747.604.818/tahun dengan R/C ratio 1,2.

TULUS ROMORA SITUMEANG. Hatchery and Grow-out of Barramundi Lates calcarifer at PT. Bali Barramundi, Buleleng, Bali). Dibimbing oleh ANDRI ISKANDAR.

Barramundi Lates calcarifer is a marine fish commodity that has the advantage of having a high market demand value with good nutritional content. Hatchery activities consist of preparation of containers, rearing broodstock with a stocked density of 1-3 fish/m3, spawning broodstock, rearing larvae, rearing seeds, harvesting, and post-harvesting. Barramundi broodstock spawns and produces eggs that collect in the egg collector, then the eggs are spread into the egg hatching container. Larval rearing was carried out when the larvae hatched until they were D16. In hatchery activities, the fertilization rate 56%, hatching rate 76% and survival rate 42% with a stocked density of 20-30 eggs/L. Business analysis of hatchery earns a profit of Rp Rp 1.025.332.465/year with an R/C ratio of 1,7. Barramundi rearing activities consist of preparation of containers on the cage, seeding, feeding, harvesting, and post-harvest. The seeds that measuring 10-12 cm can be stocked at a density of 45-50 fish/m3 and kept in floating net cages (KJA) for 6 months until they reach a size of 1000 g/fish The enlargement activity earns a profit of Rp 747.604.818/year with R/C ratio of 1,2.
