Knowra Fish farming Fish farming Fish farming is the breeding and rearing of fish under controlled conditions for food, stocking, or other uses. It includes systems ranging from inland ponds to offshore cages.
Aquaculture : The cultivation of aquatic organisms, including fish, shellfish, and algae. Fish farming is the fish-focused branch of this broader practice.
Salmon farming : The commercial rearing of salmon, commonly in marine net pens or land-based systems. Salmon farming is a prominent example of large-scale finfish production.
Eutrophication : The excessive enrichment of water with nutrients, often causing algal blooms and oxygen depletion. Uneaten feed and fish waste can add nutrients to waters around farms.
Capture fishery : The harvesting of wild aquatic organisms from natural or managed waters. It obtains fish from existing populations rather than raising them through a production cycle.
Fish hatchery : A facility where fish eggs are incubated and young fish are raised. Hatcheries supply juveniles for farms and stocking programs.
Tilapia farming : The commercial cultivation of tilapia, a group of warm-water freshwater fish. Tilapia are widely raised in ponds, tanks, and cages.
Sea lice : Parasitic copepods that attach to fish, including salmon and related species. Farmed salmon can host lice that spread to nearby wild salmonids.
Integrated multi-trophic aquaculture : An aquaculture approach that combines species from different trophic levels to use wastes as resources. It contrasts single-species farming by linking production streams within one system.
Recirculating aquaculture system : A fish-production system that filters and reuses water in a controlled environment. It allows intensive production while limiting water exchange with the surroundings.
Carp farming : The cultivation of carp species, often in freshwater ponds or integrated farms. Carp production illustrates pond-based farming with multiple species and food sources.
