biological sampling

annual catch statistics

 catch per unit effort statistics


Stock assessment and management is becoming increasingly important, as is illustrated by these statistics on the global harvest history:

 Total catch has climbed fairly steadily since the 1950's.

 Now, about 100 million metric tons/year are taken from the sea. This figure seems to be stabilizing.

 However, the harvest per capita has grown little (see Figure 2). This implies that if the current limit can not be increased, seafood availability per person will shrink as population expands. This will lead to rising prices.
