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
New research finds low levels of trust in fisheries institutions post-Brexit
Rebuilding trust in fisheries governance will be vital to create a sustainable industry post-Brexit England, according to new research. Strong trust between managers and fishers is essential for achieving sustainable fisheries, but new research from the University of East Anglia has found worryingly low levels of trust in fisheries following the UK’s departure from the European Union. Lead researcher of the Pyramids of Life project Dr. Silvia Ferrini, “We found continued low levels of trust, possibly made worse by Brexit, with further deterioration compared to previous research.” more, >>click to read<< 20:52
New Zealand: Fishing industry boasts of lowest carbon emissions – with caveats
“In 25 years at sea, I’ve seen quite a lot of changes,” Epiha says. “For example, they’re not shy at upgrading boats. Now we’re starting to see results from our fuel usage, fuel savings, reduced carbon footprint.” The 64-metre San Discovery, which he captains, is a deep-sea trawler that can produce fillets, headed and gutted fish, squid tubes, fishmeal and fish oil – all processed, packaged and labelled to export standards. “What I can hand-on-heart say is, we do care a lot about the environment,” he says. “It’s engrained in the way we operate, adjusting gear to make sure that it’s less drag on the bottom, easier to tow, because all that adds up to less fuel usage.” >click to read< 07:49
New Research Supports Opening of Currently Closed Scallop Areas
Data presented to the New England Fishery Management Council last month provide the latest evidence that long-closed areas of the Northwest Atlantic can be sustainably opened to the scallop fishery. The Fisheries Survival Fund, which represents the vast majority of full-time Atlantic Sea scallop fishermen, has long believed that these areas can be safely opened, and supports efforts to do so in light of this new evidence. The Northern Edge of Georges Bank (more formally known as Closed Area II Habitat Area of Particular Concern), has been closed to all commercial fishing activity since 1994. >click to read< 10:00
Whales Are Shrinking. Scientists Blame Commercial Fishing Gear
The findings, published today in the journal Current Biology, reveal that when fully grown, a North Atlantic right whale born today would be expected to be about one meter shorter than a whale born in 1980. The stunted growth of the whales coincides with an increasing rate of entanglements. A 2012 study from the New England Aquarium revealed,,, Researchers acknowledge that entanglements do not explain all of the reduced growth. Other factors might be climate change, collisions and noise from ships, and the shifting availability of tiny crustaceans called copepods, their primary food source. >click to read< 13:30
New research suggests 70% decline in diversity of B.C. sockeye salmon stock in past century
There are at least 13 genetically different sockeye salmon that spawn in the rivers or tributaries of the Skeena River watershed and that has not changed in 100 years, the study found. However Price and co-author John Reynolds show that the vast majority of sockeye salmon now returning to the Skeena River to spawn, some 90 per cent, are of one type that originates in the Babine River, a tributary of the Skeena River. Price says the 
predominant strain of sockeye in the Skeena River is wild, meaning fish that were not born in a hatchery or in a human controlled spawning channel, which could affect the fish’s ability to thrive as climate change and other pressures on the fish progress. >Click to read< Loss of Sockeye Diversity Threatens Skeena Salmon, Study Finds – A century ago, the Babine accounted for 68 per cent of all wild sockeye returning to the Skeena, according to the study.
