Wild marine fisheries comprise approximately 15% of all animal protein in the human diet. However, the world now faces a global fishing crisis. According to the UN Food and Agriculture Organization (FAO), 70% of all commercially important marine fish stocks are fully fished, overexploited, or depleted. The harvesting of marine fish can have genetic effects that threaten the sustainability and potential recovery of this valuable resource. For example, recent genomics work with Atlantic cod has shown that the observed reduction in size and earlier age at sexual maturity is at least partially caused by a genetic response to fishing pressure. To sustain the productivity of harvested marine fisheries populations, it is crucial to incorporate genetic considerations into management. Management plans should be developed by applying basic genetic principles combined with molecular genetic monitoring to minimize harmful genetic change.
