Predators take big bite out of declining Atlantic mackerel population

Predators ate at least twice as many Atlantic mackerel as commercial fishery landings in the decade leading up to Canada’s region-wide moratorium, according to new research by Canadian and American scientists. The study also found seals are a major predator, lending credence to what many fishermen have long claimed. The modelling study was published this month by the federal Fisheries Department and the Canadian Science Advisory Secretariat. The top predators were gannets, grey seals, dogfish and bluefin tuna. In the most conservative estimate, predators removed between 21,000 and 29,000 tonnes annually between 2012 and 2021 — at least two times greater than Canadian commercial landings reported as 11,000 tonnes per year. more, >>CLICK TO READ<< 12:26
