Aquaculture, also called aqua farming, is really the harvesting of aquatic creatures such as fish, molluscs, aquatic plants and crustaceans. This involves farming of saltwater and freshwater organisms in controlled conditions.
Nowadays, there is an increasing demand for fish and the sea cannot keep up with the need for supplies. This is the main reason why aqua farming has been introduced in an effort to help boost the production of fish to satisfy the existing demands, whether it's for freshwater, marine or shell fish.
This kind of farming has played in important role when it comes to changing the economies in many areas. In addition to satisfying the increasing demands today for fish, this approach has also contributed to certain social benefits. As a result of aquaculture initiatives, many job opportunities can now be found in this industry. While the job market for the harvesting of wild fish is declining slowly or has become stagnant.
The dietary requirements of people are also dealt with because of aqua farming. Fish contains many essential micronutrients, proteins and minerals, which are needed in our diet. As a result of mass production these days, fish has become more budget-friendly and it's now in the reach of the general masses.
Besides the social benefits, aquaculture offers lots of environmental benefits. There has been a significant level of reduction as it relates to the pressure that was placed on wild fisheries. Many fisheries worldwide have currently reached unhealthy or unsustainable levels. This sector is experiencing tremendous growth and can now bring down the amount of pressure that was created for wild fish stocks assuming that the market interest for farmed fish matches that of the wild fish.
This type of farming is said to be less dangerous for the eco system when compared to a several other traditional techniques used for fishing. Techniques such as ocean trawling will damage the substrate in the ocean to a great extent and could also lead to the killing of non-targeted species. With the help of aqua farming, these risks will be minimized.
The reported production from worldwide operations could deliver one half of the shellfish and fish that is consumed directly by humans, but there are some issues related to the consistency of the figures reported. Additionally, in the current farming process, products from substantial pounds of wild fish can be used to yield one pound of piscivorous fish such as salmon.
Some types of aquaculture include the farming of oyster, fish, shrimp, algaculture (like seaweed) as well as the farming of ornamental fish. There are particular methods of farming which include aquaponics which combines plant and fish farming.
Fish farming will have waste as a result. This waste is produced by the fish and has to be extracted from the water in order to keep the fish healthy. Conventional fish farms may dump this water in several ways. All of them are a waste of resources and sometimes a danger to the environment. However, if the aquaponics system would be introduced to fish farms, the waste problem would solve itself. Aquaponic farming utilizes the waste that the fish produce as fertilizer for the plants. This means that aquaculture mixed with hydroponic farming takes away the waste problem formed by a conventional fish farm and produces vegetables as a bonus.
