The day cage culture is getting more attention from both researchers and commercial producers. Factors such as increased fish consumption reduced wild fish and worsened farm economy has increased our interest in our fish production.

Many small or limited resource farmers are looking for alternatives to traditional crops. Aquaculture seems to be a rapidly expanding industry and offers opportunities even on a small scale.

Cage culture also gives farmers the opportunity to utilize existing water resources. In most cases, it is of limited use for other purposes.


Main concept

Choosing the right place greatly contributes to the success of the cage farm. On-site selection is important because it can significantly affect economic viability by determining capital expenditures by affecting operating costs, production rates, and mortality.  

Site selection is a key component of any aquaculture and affects both success and sustainability. Designed for the cultivation of shellfish such as milkfish, mullet, covia, pompano, perch, pearl spot, shrimp, crab and lobster, circular cages of various diameters between 2m and 15m were tested and successfully demonstrated in India.

Central Marine Fisheries Research Institute (CMFRI). Buying the right sized fish with the right stocking density is another factor that determines the success of agriculture. The stockpile density and size of stockpile fish varies by species.

Proper feeding, quality monitoring, and cage cleaning contribute to the success of cage farming. Proper care of the cage installed in an ideal location will result in a yield of 20-40 kg / m 3 in various fish species.

Cage farming involves growing fish in existing water resources while wrapped in a net cage that allows free water flow.

Aquaculture production system made of floating nets of round or square shape with the rich frame, netting material and mooring system (rope, buoy, anchor, etc.) can catch and cultivate much fish and install them in reservoirs. River, lake or sea.

Catwalk and railings are built around the floating cage battery. There are four types of fish breeding cages: i) fixed cage, ii) floating cage, iii) underwater cage and iv) underwater cage.

Economically speaking, cage culture is impacts farming with high yields and lowest carbon emissions.

Farming fish in existing water bodies continues to require one of the biggest constraints of farming on land: water with clean oxygen. Cage farms are deployed in a way that utilizes natural currents that provide oxygen and other suitable natural conditions to the fish.  

Given the high yields that can be obtained from a cage culture system, it can play an important role in increasing overall fish production in India. By adopting a cage culture, you can better take advantage of India’s long coastline, coastal conditions, and the appropriate location of the vast rider area available in other low-utility waters.

Because of the low investment and very little or no land area, this method of farming is suitable as a source of income for small income fishermen. This can be accepted as a home / female activity, as labour is minimal and can be managed by a small family.

The design of the cage and accessories can be customized according to the individual farmer’s requirements.
