Aquaculture involves cultivating freshwater, brackish water, and saltwater populations under controlled or semi-natural conditions and can be contrasted with commercial fishing, which is the harvesting of wild fish. [2] Aquaculture is also a practice used for restoring and rehabilitating marine and freshwater ecosystems.
However, animal husbandry is a larger and more technologically mature area of human agriculture and has developed better solutions to pathogen problems. Intensive aquaculture has to provide adequate water quality (oxygen, ammonia, nitrite, etc.) levels to minimize stress on the fish.
Aquaculture technology is varied with design and development requiring knowledge of mechanical, biological and environmental systems along with material engineering and instrumentation. [4] Furthermore, engineering techniques often involve solutions borrowed from wastewater treatment , fisheries, and traditional agriculture.
Since 2000, aquaculture has been the fastest growing food production sector, growing 5.8% per year, [6] supplying over 100 metric tonnes of fish, shellfish and seaweeds from 425 species in 2017. [3] [4] Global aquaculture production by country in million tonnes, 1950–2010, as reported by the FAO. Based on data sourced from the FishStat database.
The most important thing urban aquaculture provides to the society and the environment is the fact that it reuses wastewater and by-products from agriculture (Bunting et al.). This offers a valid solution to the problem of limited access to resources and this is why the urban aquaculture should be more widespread and encouraged for all the ...
Aquaculture has made up an increasingly large proportion of fisheries products produced in the Philippines, and there has been considerable research into improving aquacultural output. Philippine output in total makes up 1% of global aquaculture production, and the country is the fourth-largest producer of seaweed.
A rice-fish system is a rice polyculture, a practice that integrates rice agriculture with aquaculture, most commonly with freshwater fish. It is based on a mutually beneficial relationship between rice and fish in the same agroecosystem. The system was recognized by the FAO in 2002 as one of the first Globally Important Agricultural Heritage ...
Inland saline aquaculture is the farming or culture of aquatic animals and plants using inland (i.e. non-coastal) sources of saline groundwater rather than the more common coastal aquaculture methods. As a side benefit, it can be used to reduce the amount of salt in underground water tables, leading to an improvement in the surrounding land ...
