    Abstract

    Mariculture is the fastest growing sub-sector of aquaculture in the world. In contrast to the global scenario, where mariculture of finfishes is a well-developed industry, in India, it is gradually emerging out from its infancy. Cage farming technology is widely recognized as the most important technology in mariculture for increasing fish production to meet the food fish demand. One important aspect hindering the rapid progress of mariculture in the country is the availability of quality seeds of high value fin fishes. However, in recent years, with success in breeding and seed production technology of several high value commercially important finfishes, thankfully due to the consistent efforts of ICAR-Central Marine Fisheries Research Institute (CMFRI), the mariculture sector of the country is poised to make a serious contribution to the fish basket of the country. Presently, quality seeds are available for cobia, Indian and silver pompano, grouper, snapper and sea-bream round the year in various hatcheries of CMFRI at multiple locations. Marine finfish seed production has to be up-scaled for meeting the stocking demand of the cages. National Fisheries Development Board has already come forward in this regard, and financial grants were provided to several private shrimp hatcheries for conversion into marine finfish hatcheries with technological support from ICAR-CMFRI. Also, as establishment of broodbanks and maintaining broodstock is expensive for private hatcheries, ICAR-CMFRI has been continuously providing them yolk-sac larvae of marine finfish for larval rearing and subsequent nursery. However, keeping in view the huge demand of stockable sized seeds, multiple satellite hatcheries and satellite nursery rearing centres needs to be developed by the government in all maritime states. ICAR-CMFRI has successfully developed in the recent past seed production technology for pompano (Trachinotus mookalee and Trachinotus blochii), cobia (Rachycentron canadum), grouper (Epinephelus coioides), snapper (Lutjanus johnii) and bream (Lethrinus lentjan and Acanthopagrus berda), for the first time in the country. Around a million seeds has been continuously and consistently produced in the last few years and have been distributed to research institutes, state government owned facilities and private enterpreneurs for nursery rearing and grow-out. However, commercial level seed production, as envisaged is possible only when seed production technology is transferred to private finfish hatcheries. Presently, for orange spotted grouper and Indian pompano, manual encompassing all aspects on seed production is lacking. The present handbook on “Hatchery management of orange spotted grouper (Epinephelus coioides) and Indian pompano (Trachinotus mookalee)” would be ideal for hatchery operators and technicians, in providing them the required technical know-how on large-scale marine seed production for orange spotted grouper and Indian pompano.
