v. t. e. Aquaculture (less commonly spelled aquiculture[1]), also known as aquafarming, is the controlled cultivation ("farming") of aquatic organisms such as fish, crustaceans, mollusks, algae and other organisms of value such as aquatic plants (e.g. lotus). Aquaculture involves cultivating freshwater, brackish water, and saltwater populations ...
United Nations studies show that more than 90% of freshwater aquarium fish are captive–bred, while virtually all marine fish and invertebrates are wild-caught. Freshwater fish habitats are threatened by habitat erosion from pollution, dams and hydropower, commercial fishing, climate change, the introduction of invasive species and disease. [32]
Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. [1] Other types of filtration and environmental control are often also necessary to maintain clean water and provide a suitable habitat for fish. [2]
Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants. [1]
Fish preservation is the method of increasing the shelf life of fish and other fish products by applying the principles of different branches of science in order to keep the fish, after it has landed, in a condition wholesome and fit for human consumption. [1][2] Ancient methods of preserving fish included drying, salting, pickling and smoking.
