Following the depletion of large pelagic predator and demersal fish stocks during the 1950–1960s, the main fishery was targetted on small and medium pelagics that declined abruptly to ∼200 kton (kton = 10 3 t) at 1989–1991 after a highly productive (∼750 kton) but overfished state in the 1980s. I. It seems that Canada is failing at ocean stewardship. The absence of fish within the western, eastern and northern regions and the presence of only a fluctuating heavily exploited anchovy fishery in the southern region during the last 20 years demand an immediate common ecosystem-based fishery management policy and actions by all the coastal states. https://doi.org/10.1016/j.ocecoaman.2011.12.013.
