Abstract

Spawning and successful rearing of larvae of honeycomb grouper Epinephelus merra Bloch 1793 upto juvenile stagewas accomplished at the ¢n¢sh hatchery of Mandapam Regional Centre of Central Marine Fisheries Research Institute during 2004. The fertilized eggs were free, spherical and buoyant with size ranging from 710 to 730 mm. Complete early embryonic development took place within 24^27 h and hatching occurred.The hatchlings measured1.5mm. Mouth opening (115 mm) appeared at 72 h when the larvae were 2.2mm in size. Pectoral ¢n developed on the ¢fth day. Complete metamorphosis took place and by the 60th day the larvae transformed into juveniles (45mm) and attained skin colouration and honeycomb pattern.
