• Extensive culture is a subjective term for fish production where the culturist has minimal control over the factors that affect the fish. The cultured population is generally at a low density. Pond culture is representative of extensive fish culture.


• Intensive culture is a subjective term for fish production where the culturist has direct control over habitat, water quality and food supply. The cultured population can be at a very high density. Tank or raceway culture is representative of intensive fish culture.
