The correct option is (c).
Explanation
Fish production includes capture fishing (obtaining fish from natural resources) and fish farming (culture fishery). Fish farming can be practiced in marine environments (mariculture) or freshwater ecosystems (inland fisheries). It involves the rearing of fish in controlled environments to maximize yield.
Statement-wise Analysis
- Statement 1 is Incorrect. Fish culture can indeed be practiced in combination with a rice crop. This system is known as integrated fish farming or paddy-cum-fish culture. In this method, fish are grown in the water standing in the paddy field, allowing for the simultaneous production of grain and fish, which optimizes resource use.
- Statement 2 is Correct. Brackish water resources are areas where seawater and freshwater mix. Estuaries and lagoons are prime examples of brackish water ecosystems. These areas are significant reservoirs for fish farming, supporting species tolerant to varying salinity levels.
- Statement 3 is Correct. Aquaculture involves the active rearing of fish, often using intensive techniques such as composite fish culture. In these systems, both local and imported fish species are used, and yields are generally high due to controlled feeding, breeding, and management compared to traditional capture fishing in natural inland water bodies.
Key Takeaway: Fish farming (aquaculture) allows for high yields through intensive management and can be integrated with agriculture (e.g., rice-fish farming). Brackish water bodies like estuaries and lagoons serve as important reservoirs for specific fish cultures.
