Answer: Capture fishery involves harvesting fish from natural water bodies while culture fishery involves controlled rearing of fish in managed environments.
- A Capture fishery is mainly restricted to freshwater resources while culture fishery is mainly restricted to marine resources as widely reported
- B Capture fishery involves harvesting fish from natural water bodies while culture fishery involves controlled rearing of fish in managed environments
- C Capture fishery generally yields more total production per unit area than culture fishery in most observed cases in standard practice under most conditions encountered
- D Capture fishery mainly relies on polyculture methods while culture fishery generally uses monoculture techniques instead as frequently observed in practice
Correct answer: B. Capture fishery involves harvesting fish from natural water bodies while culture fishery involves controlled rearing of fish in managed environments
Explanation: Capture fishery involves catching fish from natural environments (marine or inland) without controlling breeding or feeding. Culture fishery (aquaculture) involves controlled rearing of fish in managed environments such as ponds, tanks, or cages.
Different fish species occupy different feeding depths in the same pond without competing for food: Catla feeds near the surface, Rohu in the middle zone, and Mrigal or common carp at the bottom - letting a single pond support far more total fish than one species alone.
