Shrimp aquaculture is 100 eco friendly

CIBA scientists say commercial interest in biofloc technology is threefold. It provides high productivity, low feed-conversion ratios FCRs and a stable culture environment.

Maturation tanks in Latin America Photo: Profile Historical background The first spawning of this species was achieved in Florida in from nauplii spawned and shipped from a wild-caught mated female from Panama.

Following good pond results and the discovery of unilateral ablation and adequate nutrition to promote maturation in Panama incommercial culture of Penaeus vannamei began in South and Central America.

Subsequent development of intensive breeding and rearing techniques led to its culture in Hawaii, mainland United States of America, and much of Central and South America by the early s.

Despite these problems, production of P.

Asia has seen a phenomenal increase in the production of P. Although no production was reported to FAO init was nearly 1 tonnes by and had overtaken the production of P.

However, due to fears over importation of exotic diseases, many Asian countries have been reluctant to promote farming of P. Similarly, most Latin American countries have strict quarantine laws or bans to prevent importation of exotic pathogens with new stocks.

Main producer countries The main producer countries of Penaeus vannamei are shown in the map, while the whole list include: Penaeus vannamei live in tropical marine habitats.

Adults live and spawn in the open ocean, while postlarvae migrate inshore to spend their juvenile, adolescent and sub-adult stages in coastal estuaries, lagoons or mangrove areas. Males become mature from 20 g and females from 28 g onwards at the age of 6—7 months.

Hatching occurs about 16 hours after spawning and fertilization.

The first stage larvae, termed nauplii, swim intermittently and are positively phototactic. Nauplii do not feed, but live on their yolk reserves. The next larval stages protozoea, mysis and early postlarvae respectively remain planktonic for some time, eat phytoplankton and zooplankton, and are carried towards the shore by tidal currents.

The postlarvae PL change their planktonic habit about 5 days after moulting into PL, move inshore and begin feeding on benthic detritus, worms, bivalves and crustaceans.

Production Production cycle of Penaeus vannamei Production systems Seed supply Captured wild seeds were used in Latin America for extensive pond culture of Penaeus vannamei until the late s.

Broodstock There are three sources for broodstock P. Broodstock are stocked in maturation tanks in dark rooms supplied with clean, filtered seawater. Feeds consist of a mixture of fresh and formulated broodstock feeds.

One eyestalk from each female is ablated, leading to repeated maturation and spawning.

It is a beneficial bacterial colony-based culture that keeps diseases at bay

Females are either spawned in communal or individual tanks to avoid disease transmission. The following afternoon, the healthy nauplii are attracted by light, collected and rinsed with seawater. Hatchery production Hatchery systems range from specialized, small, unsophisticated, often inland, backyard hatcheries to large, sophisticated and environmentally controlled installations, together with maturation units.

Water is exchanged regularly at 10— percent daily to maintain good environmental conditions.

Feeding normally consists of live food microalgae and Artemiasupplemented by micro-encapsulated, liquid or dry formulated diets. From hatching, it takes about 21 days to reach harvest at PL Nursery Most farming operations for P.CHENNAI: To help India retain its market share in global shrimp export and neutralise disease threat, Central Institute of Brackishwater Aquaculture (CIBA) is popularising ‘Biofloc’ technology, which is eco-friendly and sustainable.

With zero or minimal water exchange, biofloc is considered eco-friendly.
