What is the size of a semi-intensive fish farm pond?

Correct option is B

The size of a semi-intensive fish farm pond is typically around 1 hectare (ha). Semi-intensive fish farming involves a moderate level of management and inputs, with the pond size being suitable for a balance between extensive and intensive farming practices. This size allows for a more controlled environment compared to extensive ponds, facilitating the application of supplementary feeding and management practices to enhance fish production. The specific pond size may vary based on local conditions, species cultured, and management strategies, but a size of 1 hectare is commonly used in semi-intensive aquaculture.
