The industrial fishery supports the consequences of this overfishing while the artisanal trawling fishery showed in 1975 a relative prosperity. In conclusion, it is evident that stock degradation is chiefly caused by fisheries utilizing too narrow meshes. This is not irreversible and it is probable that a sensible widening of the meshes would permit better management of the potential... |
