and 531 t.km-3.year, respectively) show
that, although on a per hectare basis these
countries do not belong to the top inland
fish producers, they utilize very well their
renewable freshwater resources with
inland aquaculture. Puttingit in a different
way: some countries may have land
constraints whereas others may have water
constraints to developing further their
inland aquaculture.

The advanced state of inland

aquaculture could also be characterized

by its share in the total inland fish

production. Data in Table 6 demonstrate

that in 1990, in the Asia-Pacific region, as

much as 62% of the total inland fish

production originated from aquaculture

against 27% in the rest of the world.

Aquaculture produced over 75% of the

total inland fish supply in China, Hong
