Description In India, marine fish production is achieved through capture fisheries and mariculture-
culturing of finfish, shellfish, seaweed, etc., in the sea. Increasing protein
demand has to be met through increased marine fish production. As marine
capture fisheries is in a stagnating phase, the additional fish production has to
be achieved through mariculture. Technologies like cage farming and seaweed
farming are being promoted by the Indian Council of Agricultural Research
(ICAR)-Central Marine Fisheries Research Institute (CMFRI) for more than a
decade. These interventions assisted in enhancing the marine fish production and
income of the fishers. One of the anticipated issues while expanding sea cage
farming is the increased organic and inorganic load in the water and consequent
disease problems. In this context, the concept of bio-mitigation along with
increased biomass production can be adopted by integrating different groups of
commercially important aquatic species that are having varied feeding habits.
This concept is known as Integrated Multi-Trophic Aquaculture (IMTA). The
environmental and economic stability and social acceptability is ensured through
IMTA. The ICAR-CMFRI has successfully demonstrated IMTA under participatory
mode with a fishermen group by integrating seaweed Kappaphycus alvarezii
with cage farming of Cobia (Rachycentron canadum). Through demonstration,
the total seaweed produced under IMTA was 2.2 times higher than the
control. Similarly, the cobia yield was 1.3 times higher than the control. Additionally,
the total amount of carbon sequestered into farmed seaweed was 2.2 times higher than the control. At present in adoption stage, the total seaweed
produced under IMTA was 3.1 times higher than the control. Integration of
seaweed with cobia cages favorably generates additional revenue and is efficient
in reducing both organic and inorganic matter from unutilized feed and excreta
and thereby ensuring ecological balances. It is also one of the significant
mitigating measures on the adverse impact of climate change and earns carbon
credit to our country.
