This was prompted by the Northern Cod biomass falling to just 1% of earlier levels because of overfishing and the consequent nutrient deprivation in the system causing starvation of the residual fish.
Factor that contributed to this were:
· Technological advances: sonar allows fish that may have escaped detection to be caught, navigation allows them to go deeper and freezers allow boats to stay out longer.
· Environmental ignorance: an imperfect understanding of the ocean ecosystem and challenges associated with observation…
