KAJIAN TEKNIS PENDEDERAN IKAN KERAPU CANTANG (Epinephelus fuscoguttatus >< Epinephelus lanceolatus) SECARA INTENSIF DI BPBAP SITUBONDO

Grouper production in Indonesia can be supported by hybridization technology which produce grouper species with relatively faster growth and more resistance to disease. Cantang is a type of fish that was engineered crossbreeding between female tiger (Epinephelus fuscoguttatus) male Kertang lanceolatus). The purpose this study determine the stages nursery carried out at BPBAP Situbondo. method used research observation, participation, interviews. primary data needed are on infrastructure, number size seeds, feed management, water quality harvesting. presented descriptive discussing has been obtained compared theories have developed time. results indicate cantang activities start from tank preparation, filling, seed selection distribution, quality, pest disease control, grading, harvesting seeds. During practice period, seeds were spread hatcheries stocking density 3000 5000 individuals one 4 x 2.5 1 m, or equivalent 300 500 individuals/m3. distribution after acclimatization process, namely adaptation process before releasing After removed, tub given an antiseptic prevent There several factors affect rate management feeding. maintenance flowing system used, so continuously renewed. In morning, flushed soaked using fresh water, aim mucus as reduce potential for outbreaks. Nursery Situbondo run optimally paying attention cultivation, especially management.
