EDITORIAL: Ocean imbalance

Fisheries scientists, writing in the Canadian Journal of Fisheries and Aquatic Sciences, suggest that the southern Gulf of St. Lawrence cod stock may be extinct by 2050, because cod five years old and older now face an annual mortality rate of 50 per cent. The stock was already hit hard by the fishery, and collapsed in the 1990s. But it’s still not rebounding, even after years of limited fishing, and the scientists suggest that could be because the cod congregate to spawn, and are easy targets for the Gulf grey seal population, whose numbers have grown from around 6,000 in the 1960s to 100,000 in 2014. >click to read<08:20
