Knowra Aquaculture Aquaculture Aquaculture is the cultivation of aquatic organisms, including fish, shellfish, and plants, under controlled or managed conditions. It includes freshwater and marine production.
Fish farming : The raising of fish in managed systems for food, stocking, or other uses. It is the most familiar form of aquaculture, with production shaped by species and rearing conditions.
Shellfish aquaculture : The cultivation of mollusks or crustaceans, such as oysters, mussels, and shrimp. Shellfish production is a major branch that often requires little or no formulated feed.
Aquaculture pollution : Environmental contamination caused by aquaculture wastes, chemicals, or escaped organisms. Uneaten feed and animal waste can alter water quality near farms.
Capture fisheries : The harvesting of wild aquatic organisms from natural waters. It supplies seafood by catching wild populations rather than cultivating stocks.
Mariculture : The cultivation of marine organisms in seawater or coastal environments. It applies aquaculture methods to marine species and settings.
Seaweed farming : The cultivation of marine macroalgae for food, ingredients, feed, and industrial uses. It extends aquaculture beyond animals to commercially valuable aquatic plants.
Sea lice : Parasitic copepods that infest fish, including farmed salmon and wild salmonids. Open-net salmon farms can expose wild fish to parasites from concentrated stocks.
Open-net pen : A floating enclosure that holds farmed fish while allowing water to flow freely through its mesh. This common marine method exchanges water with surrounding ecosystems rather than containing wastes.
Recirculating aquaculture system : A land-based system that filters and reuses most of its culture water. Water treatment allows intensive production while limiting water exchange.
Shrimp farming : The commercial raising of shrimp in ponds, tanks, or other managed systems. It is a major aquaculture industry with distinctive disease and coastal-land-use challenges.
