A coral trout grouper is the fishery commodities to generate foreign exchange through exports, to date cultivation continued. The purpose is to obtain data and information on the dose of the right artificial feeding and can increase the survival rate of the optimum seed nursery in the juvenile coral trout in controlled tank. Research has been conducted at the hatchery and the Institute for Mariculture Reasearch and Development Gondol, Bali. Containers experiment is used is a fiber with a size of 1 m³ up to 12 containers. test animals used were seeds of coral trout, Plectropomus leopardus with initial body length on average 3 cm with each treatment density of 100 fish/m³. Coral trout, Plectropomus leopardus seed kept in fibers. This type of feed given in the form of commercial pellet feed with a protein content of 48%, and additional food such as shrimp Mysid (jembret) for 10 days. The frequency of feeding 3 times a day (morning 8:00. local time, lunch 13:00 local time, and afternoon 17:00 local time). Treatment feeding attempted is the treatment of A = 5% dose of artificial feeding, B = 10% dose of artificial feeding, C = 15% dose of artificial feeding, and D = 20% dose of artificial feeding. The study used a completely randomized design with 4 treatments, each treatment was repeated 3 times. Data were analyzed by analysis of variance. If the variance is different then conducted a further test using the smallest real difference test (BNT). The results showed that significantly different (P <0.05) on survival, feed conversion, weight gain and body length of coral trout. The highest survival rate in treatment C = 15% dose artificial feeding is. = 90.83 ± 1.80%, followed by treatment D, B, and A.

“…Budidaya kerapu saat ini mulai berkembang sehingga diperlukan benih yang tepat waktu dan ukuran secara berkesinambungan, untuk mencukupi kebutuhan benih kerapu, maka perlu dilakukan pembenihan secara masal (Sugama et al, 2001;Sutarmat et al, 2002;2003). Beberapa penelitian yang mendukung pembenihan kerapu bebek telah dilakukan antara lain perkembangan larva (Slamet et al, 1996), pakan awal (Ismi et al, 2000), lingkungan (Aslianti, 1996;Aslianti et al, 1998;Ismi et al, 2004). Hasil-hasil penelitian tersebut sudah dapat diaplikasikan untuk produksi benih kerapu secara masal di masyarakat hingga tingkat petani, sehingga benih untuk budidaya laut sudah bisa dipasok dari hasil pembenihan walaupun sampai saat ini hasil produksi dan kualitas masih perlu ditingkatkan.…”

ABSTRACT Some researches on grouper seed production have been conducted and their results have been adopted by the farmer. Currently, grouper seeds for mariculture purposes can be provided from hatchery. However, seed abnormality is still the major problem in the hatchery. Therefore, an improvement for survival rate and quality of grouper seed production is very important. The aim of this study was to improve the production and reduce the abnormalities on grouper seed stock through enrichment of larvae feed (rotifer and artemia) with DHA and EPA, Vitamin and Calcium. The larvae of humpback grouper (Cromileptes altivelis) were reared with and without enrichment. The experiment were held in concrete tank with volume of 10 m3 filled with sea water 7-8 m3. Grouper eggs were stocked at a density of 10 eggs/l, larval were reared until the juvenile age of 45 days. Treatment were repeated three times. The data was analysed with descriptive statistic. The results showed that humpback grouper larvae reared with enriched rotifers and artemia produced better survival rate (26.81%), lower seed abnormality (26.10%), and better percentage of bigger size of seeds with grade A (20.3 %), B (39.2%), and C (40.5%). Meanwhile, treatment without feed enrichment produced lower survival rate (17.57%), higher abnormality (40.20%), and lower percentage of big size of seeds with grade A (9.7%), B (26.0%), and C (64.3%).

Hal serupa Juga terjadi pada larva ikan laut yang lain seperti kakap merah (Lutj an u s a rge nti m ac u/atus) yan g mem pu nya i bukaan mulut (0 166-0,188 mm) (Doi et al , 1997) lkan kerapu bebek yang mempunyai ukuran bukaan mulut 135 mm (Slamet et a|.,1996) Figure 1 (1980) mengemukakan bahwa pada stadia larva yang mempunyai ukuran mata kecil, jarak penglihatannya pendek, kurang ta1am, dan kekontrasannya rendah Selain itu ukuran lebar mulut atas yang berhubungan dengan lebar bukaan mulut larva berdasarkan pengamatan pada percobaan ini relatif kecil yaitu pada hari ke-3: t 143 mm, hari ke-4: t '152 mm, hari ke-S: t 170 mm, hari ke-6: t 190 mm, harike-7: t 210 mm dan hari ke-8: t 232mm, sedangkan rotifer tipe SS yang diberikan mempunyai ukuran 145-150 mm dan ukuran nauplius Acartia sp pada stadia N-'l: 100 mm, N-2: 120 mm, N-3: '150 mm, N-4:…”
