 Cage culture is a technology which fish are reared from fry to
fingerling, fingerling size to marketable size while captive in
an enclosed space that maintains the free exchange of water
with the surrounding water body.
(Bhowmick 2011, Kranatak and Kumar 2014).
Fig- Chhirpani Reservoir cages (Dist. Kabirdham)
 Cage culture was first originated nearly 200 years ago in
Cambodia where fishermen used to keep Clarias spp.
 Cage culture is popular traditional culture practiced in
Indonesia.
 Common carp culture in bamboo-cage is practised in West
Java since early 1940.
 Modern cage culture in open water-bodies started in Japan in
early 1950s.
 Presently more than 62 countries are practicing the cage
culture.
 Currently 80 species of finfish are being cultured in cage.

 In India, cage culture was attempted for the first time in 1970
in three environments:-
1) Swamps marked by low DO concentration, using air-
breathing fishes.
2) Running waters of the Yamuna and Ganga Rivers at
Allahabad, using major carps.
3) Standing water body in Karnataka, using common carp,
catla, silver carp, rohu, snakeheads and tilapia.
 The Central Inland Fisheries Research Institute (CIFRI)
attempted cage culture in the 1970s with the production of air-
breathing fish in cage but got poor result (Das et al., 2014).
4 types of cage are being used for cage aquaculture.
 Fixed cage
 Floating cage
 Submersible cage, and
 Submerged cage

  • 6. 4 types of cage are being used for cage aquaculture.  Fixed cage  Floating cage  Submersible cage, and  Submerged cage Source:- Shrivastava at al.(2009).
  • 7.  Fixed cage though very primitive in origin, still in vogue.  It is used in shallow water body part with water depth of 1-3m in reservoir.
  • 8.  Floating cage is supported by a floating frame where in net bags are kept hanging in water without touching the basin.  Water bodies in depth more than 5m in reservoir.
  • 9.  Submersible cages have net bags suspended from surface with adjustable buoyancy  It may be rigid or flexible.
  • 10.  It have net bag fitted in a solid and strong frame and submerged under water  Operational mainly in marine environment.
  • 11.  The cage are generally enclosed on all sides, except an opening at the top for feeding and handling the fish stock.  Cage may be round, square or rectangular in shape.  Round cages with a cylindrical net, supported by circle-shaped support frames are most used for sea cage culture in India.  Cube-shaped, rectangular/square cage are used in reservoirs. Source- Manna and Hassan, 2004
  • 12.  Size of cage for fish culture in reservoir can vary, but often multiple units are installed as a battery of cages.  A cage with the dimensions of 6m x 4m x 4m is mostly considered(Manna and Hassan ,2004).  Standard unit and battery comprises 6, 12 or 24 such cage, as per requirement(Manna and Hassan, 2004).  The cage in a battery are arranged in caterpillar design for better exchange of water thereby facilitating relatively high dissolved oxygen (Bhowmick et al. 2015 ).
  • 15.  Durable and stable cage materials are essential for achieving better results.  A cage comprises hard frames as support and nylon netting as cage body.  The material should be of - Environment-friendly HACCP protocol compliant Rust-free material for cage fabrication. Commonly used material for cage frames are bamboos.
  • 16. - Mild-steel(MS) - Galvanized iron(GI) - Poly-vinyl chloride(PVC) - Virgin-grade HDPE(High Density Polyethylene) - The bamboo based frames are not recommended for commercial cage fish farming due to their poor longevity and strength to withstand turbulence.
  • 17. Site selection Water depth:-  The cage site needs a water depth of at least 5-10 meters round the year.  3-4 meters depth will be always needed from the cage bottom to the floor of the water body. Wave and wind- - Avoid strong wind, wave and current river, canal, reservoir.  Water current - River and reservoir: 28-50cm/s - wave lower: 2 meter Fish seed availability Source- Bhowmick et al, (2015).
  • 18.  Anti-corrosive paint should be applied to prevent rusting and to increase the durability.  Cage should be cleaned at 15 days interval to avoid net clogging.  The physico-chemical parameters of water should be recorded regularly as a part of water quality monitoring. Source- Das at al., (2015).
  • 19.  DO: 4-6mg/lit.  Temperature – 25-300c  Salinity – less then 0.5ppt(depends on species)  pH- 6.5-8.5  NH3- 0.5 mg/l Source- Das et al, (2015).
  • 20. o Sandy bottom is preferred. o Avoid acidic and red tide water. o Easy for transportation, electricity, nearby feed source and market.
  • 21.  The MOA, Government of India, has classified reservoir as small (<1000 ha), medium (1000 to 5000 ha) and large (>5000 ha) for the purpose of fisheries management.  India has 19,370 reservoir spread over more than 15 states with an estimate 3.15 million ha surface area at full capacity (Sugunan, 2015).  It has been reported that more than 15 states had adopted the cage culture technology in inland water with fish production in the range of 15-17 kg /m3/year (Sharma, et al., 2015).  Cage farming has been proven successful in the states of Jharkhand and Chhattisgarh (Das and Sharma 2015).

  • 27.  Occupy a small area of river, canal or reservoir.  Cage can be available and cheap materials.  Poor farming can manage small cage culture.  Fish can be stocked with high density fast growth.  Yield and profit are high.  Easy to harvest.
  • 28.  Disease out break is common: - High density, - Contamination from other, - Quick change of environment,  Culture cycle depends much on season and culture cage is affected by flood, storm and strong waves.  In some case, cage becomes obstacles for transportation and landscape.
  • 29.  High stocking density can be done in such culture system.  Utilization of open reservoir.  Less time fast growth rate with supplementary feeding.  Suitable for culture of hardy species (e.g.- monosex tilapia, pangasius).  Entrepreneurship and employment opportunity leading to improvement of the people.
