- A fishprint provides a measure of a country’s fish harvestin terms of area. The unit of area used in fishprint analysisis the global hectare (gha), a unit weighted to reflect therelative ecological productivity of the area fished. Whencompared with the fishing area’s sustainable biocapacity (itsability to provide a stable supply of fish year after year,expressed in terms of yield per area), its fishprint indicateswhether the country’s annual fishing harvest is sustainable. The fishprint and biocapacity are calculated using thefollowing formulas:Fishprint in (gha) = metric tons of fish harvestedper year/productivity in metric tons per hectare ×weighting factorBiocapacity in (gha) = sustained yield of fish in metrictons per year/productivity in metric tons per hectare ×weighting factorThe following graph shows the earth’s total fishprint andbiocapacity between 1950 and 2000.
