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 u...

Abstract The use of recirculating aquaculture system (RAS) in nurseries cantik grouper ( Epinephelus fuscoguttatus × microdon ) has the potential to make culture environment more stable and maximize production perfomance, but work RAS decreases with accumulation waste water used. Remediation microorganisms (bioremediation) can improve performance RAS. This research aims determine best dose comm...
