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.
Fed aquaculture (e.g. fish and shrimp) is combined with inorganic extractive (e.g. seaweed) and organic extractive (e.g. shellfish) aquaculture to create balanced systems for environmental sustainability (biomitigation), economic stability (product diversification and risk reduction) and social acceptability (better management practices).
Intensive agriculture, also known as intensive farming (as opposed to extensive farming), conventional, or industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per unit of agricultural land area.
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 ]
Fish chosen for extensive aquaculture are very hardy and often do well in high densities. Seaweed, prawns, mussels, carp, tilapia, tuna and salmon are the most prominent forms of extensive aqua cultured seafood. Extensive aquaculture facilities have negative impacts on the environment as well.
Farmers combine fed aquaculture (e.g., fish, shrimp) with inorganic extractive (e.g., seaweed) and organic extractive (e.g., shellfish) aquaculture to create balanced systems for environment remediation (biomitigation), economic stability (improved output, lower cost, product diversification and risk reduction) and social acceptability (better ...
IMS aquaculture is similar to extensive farming in that it doesn't depend on chemical inputs, formulated feed and shrimp larvae but instead relies on natural feed and natural shrimp recruitment from the exchange of tidal water. [2] [4] [8] Silvoaquaculture, is a manageable alternative for small-scale farmers who lack access to financial support.
Comprehensive instrumentation and sensor controls are required to monitor this equipment and the underlying water conditions such as temperature, dissolved oxygen, and pH. Development of recirculating aquaculture systems is still underway in 2017, and engineering advances are needed to make the systems economically viable for culturing most ...
