Drinkwater (2002) showed that lower temperatures led to slower growth rates
and that 30–50% of the decline in cod biomass was due to reduced weight of fish
at a given age. It is known that fishermen were systematically dumping underweight
cod in the hope of filling their quota with larger fish in better condition.
This practice, known as “high grading,” contributed to the very high fishing mortalities
recorded during the last decade of the fishery.
