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
North Atlantic right whale population has steadied, scientists say
The population of critically endangered North Atlantic right whales appears to have levelled off after a decade of steep decline, according to updated data released this morning by Canadian and American scientists. Every fall, the North Atlantic Right Whale Consortium releases its best population estimate of the world’s most threatened large whale. Scientists in the consortium said Monday that the 2021 estimate of 340 North Atlantic right whales in existence has been recalculated to 365 primarily because of the number of calves born that year. The estimate for 2022 is 356. >>click to read<< 09:52
