Notes 1. The word fishery includes finfish, crustaceans, molluscs, and other miscellaneous animals but excludes the harvest of plants.

2. Potential production is calculated using standard coefficients relating the surface of water bodies (river or floodplain) to potential production rates (metric tons per hectare per year) as typically observed for these water bodies and classically used in the literature (see, for example, Welcomme 2001).
