Globally, India stands second in inland fish production next to China, but there is a huge gap in fish production between these two leading aquaculture countries. The prime objective of cage culture in inland open water is the stocking of reservoirs and culture of economically important fishes for augmenting fish production.
Cage culture in inland open waters is being evaluated as an opportunity to use existing reservoirs and meet the increasing demand for animal protein in the country. Reservoirs in India offer substantial scope for implementation of technology for intensive cage farming to realise water productivity, entrepreneurship and employment opportunities.
Cage culture
Cage culture is an emerging technology through which fishes are reared from fry to fingerling, and then from fingerling to marketable size while kept captive in an enclosed space that maintains the free exchange of water with the surrounding water body. A cage is enclosed on all sides with mesh netting made from synthetic material that resists decomposition in water for a long period of time.
In India, cage culture in inland water bodies was initiated for the first time in air breathing fishes in swamps, for raising major carps in running waters in Jamuna and Ganga at Allahabad, and for raising carps, snakeheads, and tilapia in lentic (still water) bodies of Karnataka.
Thereafter the cages have been used for rearing fry in many reservoirs and floodplain wetlands to produce advanced fingerlings for stocking main water bodies. India has 19,370 reservoirs spread over 15 states with an estimated 3.15 million ha surface area at full capacity, and this is expected to increase due to the execution of various water projects in the country.
Evolution of cage culture
In India, the Central Inland Fisheries Research Institute (CIFRI) attempted cage culture in the 1970s with the production of air-breathing fish in cages. Subsequently, trials with major carps were conducted in cages installed in river Yamuna and Ganga at Allahabad. Similar attempts were made with common carp, silver carp, rohu, snakeheads and tilapia in a still water body of Karnataka. The growth of cage farming got momentum during 2010-2012 with funding support from National Fisheries Development Board (NFDB), National Mission on Protein Supplementation (NMPS), Rashtriya Krishi Vikas Yojna (RKVY), etc. This paved a way for the dissemination and adoption of this technology in a number of reservoirs belonging to more than 15 states in ‘Mission Mode’ through NMPS scheme. The states of Jharkhand, Chhattisgarh, Madhya Pradesh, Maharashtra, Telangana and Andhra Pradesh have widely adopted and upscaled cage culture technology.
