Fisheries and aquaculture supplied the world with about 145m tonnes in 2009, providing about 16% of the population’s animal protein intake.
It said that about 32% were overexploited, depleted or recovering.
“The percentage of overexploitation needs to go down, although at least we seem to reaching a plateau,” he observed.
The authors added that it was estimated that the level of overexploitation had increased slightly since 2006, but 15% of the stocks monitored by the FAO were either “underexploited” or “moderately exploited”.
This meant that catches in these regions could increase in order to meet the demand for fish products.
