Affordable, easy to manage fish cages with a production capacity of upto 312 fish per cubic meter made using bamboo, eucalyptus and low cost metal.
Raising fish in cages is a successful system used in many parts of the world. It has replaced the traditional fish-growing method of earth ponds. Its advantages are well recognized and it is widely spread all over the globe. The first and most important advantage is the unlimited amount of water surrounding the cages. This unlimited water supply provides vast amounts of oxygen and running water which is necessary for productive fish farming. Secondly, the financial investment in such a system is much lower. This system of cages is simpler in daily operation in comparison to any other commonly used method of growing fish.

The success of your fish farming business is dependent on many factors including the selection of a suitable site for your fish farm and the design and construction of facilities that enable efficient and economic operation.
A new technology to boost commercial fish farming in lakes, dams, reservoirs and rivers is being transferred from China to Uganda. The metal cage fish technology is being introduced by Chinese scientists through a three-year China-Uganda cooperation in aquaculture research, according to Barry Kamira, a research scientist at the National Fisheries Resources and Research Institute (NaFIRRI) and the coordinator of the project. The project started in April 2012.
Cage technology, unlike pond fish farming, relies on metal cages of various sizes that are suspended in a water body. Each cage carries up to 10,000 fingerlings. Fish farmers use a measure of their efficiency in converting food mass into increased body weight to know when to transfer the young fish to the next cage until they mature for harvesting six months later.
When the trial ends, the Ugandan government is expected to roll out the technology nationally. Uganda is taking the lead among the East African countries — Kenya and Tanzania to demonstrate the potential of rearing fish using metal cage fish farming technology to rapidly transform the sector from subsistence to commercial fish farming.
