Jharkhand sets a new trend in growing fish through the cage culture


Jharkhand has set in motion a new trend in fish cultivation – it is the cage culture that has seen its output grow from 14,000-metric tonnes in 2000 to a phenomenal 1.6-lakh metric tonnes in 2014. This cage culture of incubating fish in a controlled environment has paid rich dividends and has given the state the tag of a mentor fisherman for others.
This has been reported in telegraphindia.com dated 24 September 2015.
The cage culture had been introduced on an experiment basis in 2011 at Ranchi's Hatia dam and the success is attracting teams from across states to learn the technique and replicate it back home.
An 18-member Rajasthan team, consisting of 15 fishermen from tribal belts of three districts and three officials of the desert state's fisheries department have come to Ranchi for a week-long exposure trip on cage culture.
Earlier, between July-end and first week of August, a team from Jharkhand fisheries department had visited Telangana at the invitation of the state government to help them set up cages in six water bodies. That was after the Telangana fisheries department had sent 200 fishermen for a fortnight's training to Ranchi.
About cage culture – it is a proven method to grow fish faster in a controlled environment. It involves water-resistant cages that are covered with nets and released in water. Before releasing fingerlings or small fish freely in a large water body, they are kept in cages and nourished by means of artificial feeding. Drums are fitted below the cages to prevent them from drowning and to ensure that the fish get regular oxygen supply.
Already there are 2,000 cages positioned in 14 prominent dams/ reservoirs in Ranchi and another 1400 are proposed to be added.
