To disseminate technologies to Entrepreneurs/Govt. organizations.

Salient features of the Project

The seabass brooders are maintaining in Recirculation Aquaculture System (RAS) and selected male and females are maintaining in controlled environment tanks which is connected to the heater and chiller units.

Year-round production of Algae, Rotifer and larval rearing is standardized.

In larval rearing section improved survival from 30 % to 80% which was done by improving live feed operations and protocol for weaning diet.

The weaned fry/fingerlings are supplying to the farmers/entrepreneurs and conducting several hands-on training programmes for the importance of larval rearing.

Perfected in the RAS system in Broodstock Housing Facility.

Rotifer production technology improved and standardized to produce rotifer of about 150-200 nos/ml in all the seasons in out-door section.

Contacting regular Hands-on training programmes on Best Management Practice for Seabass Aquaculture.

RGCA offering national level consultancy services for Seabass Seed production technology to the private entrepreneurs and Govt. departments.
