The ICAR-Central Institute of Brackishwater Aquaculture (ICAR-CIBA) in collaboration with the National Institute of Ocean Technology (NIOT) has successfully developed Asian seabass fish (Lates calcarifer) cage farming in the Buckingham canal waters in Tamil Nadu state.

The project developers informed that a novel three tier model comprising nursery rearing, pre-grow out and grow out cages were taken up in a phased manner.

The farming cycle began with stocking of fish fry (1cm size) initially in the nursery cages and they were grown to fingerlings size in 45-60 days, until reaching 7-8 cm in size. Then, they were transferred from nurseries to pre-grow-out cages and then 90-100g juveniles from pre-grow out were moved to other grow out cages for further rearing.

The seabass specimens were fed with CIBA’s formulated indigenous feed (SeebassPlus) and the juveniles were grown to a marketable size of 900 g - 1.25 kg in 6 months.

A productivity of 460 kg was obtained in two partial harvests in one cycle. Two cycles of production can be taken in a year.

The production cost was worked out to be INR 190 (USD 2.9) per kg of fish and sale price was INR 380 (USD 5.9) per kg with a B:C ratio of 2.0.

The fish producers were linked to Tamil Nadu Fisheries Development Corporation, a state government body which procures fish from producers giving farm gate price and sale to the consumers through its outlets.

The government aims to transfer the technology used for this project to other coastal villages in order to improve local people’s livelihood and income.

To this end, Shri Ajay Anand, Joint Director of Fisheries at the Pondicherry Union Territory, informed that their department has already initiated a work plan with CIBA to take up cage farming in the backwaters of the territory.

Dr. M. Kumaran, Principal Scientist and coordinator of the programme, asserted that this three-tier cage farming model can be available for fishers as an alternative livelihood option, and also an employment opportunity.
