The development of mariculture is fully dependent on the availability seed of the fish or shell fish to be cultured. For this, hatchery production of the seed is imperative owing to the uncertain nature of natural seed resources. At present the seed production technology of some species with mariculture potential have been developed in India, which includes Cobia, Rachycentron canadum, Silver/Snubnose pompano, Trachinotus blochii, Indian pompano, T.mookalee, Orange spotted grouper, Epinephelus coioides, Sea bream, Lethrinus lentjan, Asian sea bass, Lates calcarifer etc
