Berhampur, August 21 (LocalWire): In its bid to boost production of popular fish species like catla, rohu, and mrigala, the state Fisheries and Animal Development Department has decided to introduce circular cage fish farming at major reservoirs in Ganjam district from this year.
In the first phase of the trial, circular cage fishing would be introduced in Salia and Rushikulya reservoirs, respectively, at Beguniapada and Sorada in the district.
The department had tested rectangular cage fish farming at three places in Salia reservoir in 2018 and while it had introduced the concept in Sorada and Baghalati reservoirs as well, no one came forward to take up, sources said.
“Production of fish from the rectangular cage was not satisfactory and only some species of fishes could be grown in the cages,” Berhampur zone deputy director of fisheries (DDF) Siba Prasad Bhoi said.
He further informed that the department had decided to switch over from rectangular to circular cage fish farming this year on a pilot basis.
“In a circular cage, fishes will get more space for their movement which will boost their growth. The cage would be enclosed with mesh net made from synthetic materials.
The diameter and depth of each cage will be 10-meter and six-meter respectively,” the DDF said.
“It will help to boost the production of fishes like rohu and catla, which are in much demand among the people of the state,” he added.
According to Bhoi, two circular cages were installed in Hirakud dam reservoir in Sambalpur for the first time on an experimental basis and the results were promising
The deputy director pointed out that the department expects to produce around 40 tonne of fishes per annum as against over five tonne produced in the rectangular cage fishing.
“A unit of the circular cage would cost about Rs one crore,” he said.
After installation of the circular cage in the reservoirs, they would release the fingerlings of different popular species of fishes into the cages, Bhoi said.
