Bhubaneswar, Aug 3: Odisha has vast fresh water resources extending around 6.84 lakh hectares. During 2019-20, Odisha produced around 8.16 lakh Metric tonnes of fish.

The demand and consumption of freshwater fish such as Indian Major Carps and other varieties are ever-increasing in Odisha. In order to increase the freshwater fish production, the State Government has come out with a new policy to promote cage culture in medium and large reservoirs of the State.

Utilizing a modest fraction (1%) of the surface area, the large and medium reservoirs can contribute a substantial quantity of fish to the total inland fish production basket of Odisha.

Cage Culture fisheries is an emerging technology for the intensive production of fish and has a huge potential for increasing fish production. It is often considered as the future of reservoir fisheries which can lead to achieving self-sufficiency in the fish demand of the state and also promote entrepreneurship in aquaculture and create job opportunities.

The Cages are enclosed spaces to rear fish in reservoirs and are generally enclosed on all sides with net walls, except for leaving an opening at the top for feeding and handling the fish stock. The Cages are of many shapes (circular, square, or rectangular) and are equally good from the production point of view and their choice is mainly based on considerations such as fish species to be farmed, endurance, cost, availability of materials, convenience in assembling and transporting the components.

In the first phase, cage culture will be promoted in 5 zones and 100 subzones of the Hirakud reservoir which can cover around 2400 cages. These identified sub-zones will be leased out to Primary Fishery Cooperative Societies, Fish Farmers, Private entrepreneurs or companies. Each sub-zone has a cage surface area of 600 m? and can accommodate a maximum of 24 nos. of rectangular cages of 6 m length x 4 m width x 4 m depth dimension or 3 nos. of circular cages of 16 m diameter. In a rectangular cage, around 3000 kg of fish can be harvested.

Various fish species like Catla, Rohu, Mrigal, Amur Carp, Pangasius, Mono-sex GIFT tilapia, Asian Seabass/Barramundi, Pearl spot, Butter catfish, etc will be allowed to be cage cultured. The cage culture guidelines have strict conditions for maintaining water quality, cage maintenance, fish health monitoring, etc.

The Fisheries and Animal Resources Department through the Director of Fisheries has invited Expression of Interests (EOI) from interested farmers and entrepreneurs for availing long term lease (5 years extendable to a maximum of another 5 years) of the subzones in Hirakud reservoir.
