Description 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.
