Recirculating aquaculture systems often involve intensive, high-density culture of a species with limited water usage and extensive filtration. In a typical recirculating aquaculture system, a series of filtration steps maintains a high level of water quality that promotes rapid fish growth. [6]
A biofilter and CO 2 degasser on an outdoor recirculating aquaculture system used to grow largemouth bass Water treatment processes needed in a recirculating aquaculture system. A series of treatment processes is utilized to maintain water quality in intensive fish farming operations. These steps are often done in order or sometimes in tandem.

Grist reports that both aquaculture and fisheries have environmental and climate impacts and this underscores the need to transform seafood systems to minimize their impact on the planet.
Apart from fish and shrimp, some aquaculture undertakings, such as seaweed and filter-feeding bivalve mollusks like oysters, clams, mussels and scallops, are relatively benign and even environmentally restorative. [12] Filter-feeders filter pollutants as well as nutrients from the water, improving water quality. [156]
Fisheries science is the academic discipline of managing and understanding fisheries. [1] It is a multidisciplinary science, which draws on the disciplines of limnology, oceanography, freshwater biology, marine biology, meteorology, conservation, ecology, population dynamics, economics, statistics, decision analysis, management, and many others in an attempt to provide an integrated picture of ...
Trout do best in spring water because it keeps a constant temperature, while catfish need a strong flow, about 80 litres per second for every 0.4 hectares of raceway. A backup water supply should be positioned so, if the water supply or pump fails, it can flow by gravity into the start of the raceway. [16]
Aquaculture Research is a peer-reviewed academic journal on fisheries science and aquaculture published by John Wiley & Sons since 1970. The journal is abstracted and indexed in the Science Citation Index, Scopus, AGRICOLA, Biosis, Food Science & Technology Abstracts, Academic Search Premier, and GEOBASE. [1]
