  2. Recirculating aquaculture system - Wikipedia

    en.wikipedia.org/wiki/Recirculating_aquaculture...

    Reoxygenating the system water is a crucial part to obtaining high production densities. Fish require oxygen to metabolize food and grow, as do bacteria communities in the biofilter. Dissolved oxygen levels can be increased through two methods, aeration and oxygenation. In aeration air is pumped through an air stone or similar device that ...

  3. Raceway (aquaculture) - Wikipedia

    en.wikipedia.org/wiki/Raceway_(aquaculture)

    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]

  4. Aquaponics - Wikipedia

    en.wikipedia.org/wiki/Aquaponics

    Fish and other aquatic animals are the primary consumers in an aquaponic system, providing a source of protein and nutrients for the plants. A variety of fish species can be used in aquaponic systems, including tilapia, goldfish, and koi. Fish help to fertilize the plants by producing 'waste' that is rich in nutrients

  5. Aquaculture - Wikipedia

    en.wikipedia.org/wiki/Aquaculture

    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).

  6. Rice-fish system - Wikipedia

    en.wikipedia.org/wiki/Rice-fish_system

    The benefits of rice-fish systems include increased rice yield, the production of an additional (fish) crop on the same land, diversification of farm production, increased food security, and reduced need for inputs of fertilizer and pesticide. Because fish eat insects and snails, the systems may reduce mosquito-borne diseases such as malaria ...

  7. Saltwater aquaponics - Wikipedia

    en.wikipedia.org/wiki/Saltwater_aquaponics

    Saltwater aquaponics (also known as marine aquaponics) is a combination of plant cultivation and fish rearing (also called aquaculture), systems with similarities to standard aquaponics, except that it uses saltwater instead of the more commonly used freshwater.

  8. Commercial fish feed - Wikipedia

    en.wikipedia.org/wiki/Commercial_fish_feed

    In the current technology, fish feed extruders play a key role in production lines. Although the majority of the process of the fish feed production occurs in the extruder, grinding and mixing can highly affect the quality of the final product. [14] Water is added and the resulting paste is extruded through holes in a metal plate. The diameter ...

  9. Seaweed fertiliser - Wikipedia

    en.wikipedia.org/wiki/Seaweed_fertiliser

    On a broader socio-ecological scale, seaweed aquaculture and fertilizer development have significant roles in biogeochemical nutrient cycling through carbon storage and the uptake of nitrogen and phosphorus. [4] [5] Seaweed fertilizer application to soils can also alter the structure and function of microbial communities.
