Today cage culture is receiving more attention by both researchers and commercial producers. The high demand for fish puts a lot of pressure on the aquaculture industry to increase capacity. Many small or limited resource farmers are looking for alternatives to traditional agricultural crops. Aquaculture appears to be a rapidly expanding industry and it offer opportunities even on a small scale. Cage Farming culture also offers the farmer a chance to utilize existing water resources in which most cases have only limited use for other purposes.
Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions. The most important fish species used in fish farming are worldwide, in order, salmon, catfish carp and tilapia.
Cage Farming aquaculture differs from open aquaculture in one major aspect: In cage aquaculture the fish are contained in an artificial enclosure that is placed in the water. Enclosures for cage aquaculture are often located in waters that are utilized for other purposes, or that are populated by species that are not cultivated. By contrast, open aquaculture involves cultivating fish in bodies of water that are exclusively devoted to that process. In most instances, open aquaculture takes place in artificially created bodies of water.
Fish cages are placed in lakes, bayous, ponds, rivers, or oceans to contain and protect fish until they can be harvested. The method is also called “off-shore cultivation”. when the cages are placed in the sea. They can be constructed of a wide variety of components. Fish are stocked in cages, artificially fed, and harvested when they reach market size. A few advantages of fish farming with cages are that many types of waters can be used (rivers, lakes, filled quarries, etc.), many types of fish can be raised, and fish farming can co-exist with sport fishing and other water uses.
Cage farming of fishes in open seas is also gaining popularity. Given concerns of disease, poaching, poor water quality, etc., generally pond systems are considered more simple to start and easier to manage. Also, past occurrences of cage-failures leading to escapes, have raised concern regarding the culture of non-native fish species in dam or open-water cages.
Cage farming allows bodies of water to be available for several purposes simultaneously, including recreational uses. It’s also possible to relocate a fish cage farm to maintain water quality and environmental sustainability. Cage farming also allows for larger harvests than cultivation of dedicated fish ponds. Cultivation of fish that require deeper waters is more feasible for cage farms located in open waters than for farms located in dedicated pools. Cage farming also allows fish larger areas for swimming, which encourages more compact muscle growth and leaner meats.
