Rathacharen, S.; Laxminarayana, A.; Venkatasami, O.; Codabaccus, B.
The adult shrimps, Penaeus monodon and Metapenaeus monoceros were induced to mature and spawn by eyestalk ablation. The larvae of both the species of shrimps were reared up to post larval stage on a diet of the phytoplankton, Chaetoceros calcitrans. The post larvae of M. monoceros were fed with artificial feeds only, whereas the post larvae of P. monodon were fed on small quantities of Artemia sp. in addition to artificial feed. After post larval stage, PL-20, the post-larvae were acclimatized to freshwater. Acclimatization was tried for different periods ranging between 2 and 20 days. The best survival rate was obtained for an acclimatization period of 5 days. Results obtained so far showed that the growth of P. monodon was significantly higher in freshwater. The methodologies of larval rearing, acclimatization and the results obtained on the growth of P. monodon in freshwater and seawater are described.

The silver sea bream (Rhabdosargus sarba), has great commercial value in Mauritius. The species is a potential candidate for aquaculture. The sea bream, a winter spawner, was successfully induced to breed in captivity with HCG (Human Chorionic Gonadotropin) hormone injection (250 IU/kg body weight) in 1989 at the Albion Fisheries Research Centre. In 1997, the Coastal Fisheries Resources and Environment Conservation Project of Japanese International Cooperation Agency (JICA) was launched to enhance the stock of the silver sea bream in the lagoon. This species breeds under hatchery conditions during the spawning season. Annually, the hatchery-produced sea bream fingerlings, of 2.0 to 2.5 cm body length, were released in the coastal areas. The larval rearing method adopted at the Albion Fisheries Research Centre is described.

Hassea, R.; Codabaccus, B.; Rathacharen, S.; Khadun, S.
The mangrove crab, Scylla serrata (Forskal) is a potential candidate for aquaculture development in Mauritius and experimental trials on its culture were carried out from 1997 to 2002. It has a fast growth rate and tolerates a wide range of physico-chemical parameters. The survival rate of Scylla serrata, both under the controlled/hatchery conditions and in the natural eco-habitat is low. In 1997, the Japan International Cooperation Agency (JICA) launched the “Coastal Fisheries Resources & Environment Conservation Project” to enhance the stock of crab in the lagoon waters. The quantity of crab juveniles for culture in barachois is dependent on the availability of seed in the lagoon. Hatchery-produced crab juveniles were reared for experimentation/study in pen enclosures in two barachois prior to release in the coastal areas. The bio-indicators, stocking density and feeding regime differed in the two experimental studies. These experiments indicated varying survival and growth rates using different feeding regimes and stocking densities.

The Fisheries division of the Ministry of Fisheries and Cooperatives is involved in research, development,
management and protection of fishery resources of Mauritius. It is divided into a Fishery Research and
Development Service and a Fisheries Protection Service. The latter section is primarily concerned with the
protection of fishery resources and enforcement of Fisheries Act. The Albion Fisheries Research Centre
(AFRC), established in 1982, comprises the technical services of the Ministry and is responsible for research
and development in the fishery sector. Its activities include resource assessment and management, development
of fishing technology, fish quality inspection, studies on the marine environment, establishment of marine parks,
and aquaculture research.
