Non-Fishing Mortality Remains Key Concern in South Coast Cod Update
Today’s 3Ps cod stock assessment update delivered some good news for harvesters on the province’s south coast, but significant concerns regarding natural mortality and the untold impact of seal predation remain. “Fish harvesters on the south coast are looking for better science on this cod stock,” says FFAW-Unifor President Keith Sullivan. “Natural mortality has been driving the stock for many years. We already know that seals are eating a large amount of cod, but DFO needs their scientists to prove it first. Yet several years into this and we’ve made very little headway,” >click to read< 16:39
Southern Newfoundland cod stocks expected to be in ‘critical zone’ until early 2024
In a presentation of the assessment’s findings on Friday, stock assessment biologist Karen Dwyer said cod born in 2011 have been supporting the 3PS stock, between southern Newfoundland and St-Pierre-Miquelon, and the fishery over the last few years. She said “recruitment”, fish younger than two years old, have dropped to historically low levels. Very few fish have been born in any one year since 2011,,, Some factors affecting the health of the cod stock could be the changes in the ecosystem, said Dwyer. Meanwhile, the debate over whether seals are among the biggest reasons for the deterioration of the cod stock in 3Ps is far from over. >click to read< 15:50
“DFO operates in denial of Reality”- Scientist says seal predation not having a significant impact on spawning cod stocks
Instead, Karen Dwyer, weighing in on the contentious debate over the health of cod stocks, said Thursday that environmental factors and a limited supply of the cod’s primary food source — capelin — are more to blame.,, Trinity Bay fisherman Keith Smith said DFO continues to downplay the impact of seal predation on cod. “It’s like DFO operate in denial of reality,” Smith said. “Fishing mortality is at an all-time low while natural mortality, likely led by the growing seal population that consumes vast amounts of both capelin and cod, remains high,”,,, >click to read< 11:04
Scientist says DFO may be overestimating Newfoundland cod stocks by 35 per cent
A British Columbia fishery scientist says he’s worried federal Department of Fisheries and Oceans managers aren’t getting an accurate picture of the state of the northern cod stock. In fact, George Rose’s research suggests DFO science may be overestimating the biomass of the stock by 35 per cent.,,, The president of the FISH-NL union says DFO should take the criticism seriously. Cleary is calling for the cancellation of all fishing for northern cod outside the stewardship fishery, including the recreational food fishery, which is not something the union takes lightly, he said. >click to read< 19:10
DFO scientists clarify the decline of cod
In a province where the fishery is foundational to its survival, the decline in cod stocks has many worried and searching for clear answers. This announcement was a particular shock as the same assessment in 2016 predicted a considerable increase in cod numbers for this year. But scientists and harvesters who had noted the declines in the cod’s food source, and the many starving fish of last year’s cod fishery, were not as surprised. Research scientist with the department of Fisheries and Oceans Dr. Mariano Koen-Alonso says the sudden and sharp decline in cod stock is something being seen across the ecosystem. >click to read<11:30
Northern cod stock declined over last year; scientists urge minimum fishing effort
Those in the province’s fishing industry hoping the northern cod would be ready for a commercial fishery in a few years’ time — a saviour to an industry suffering repeated blows from declining crab and shrimp stocks — better hold on to their hooks and nets. Northern cod this year are in the same leaky boat, having declined significantly over the past year. And that has come as a surprise to many because the northern cod stocks off the province’s east and northeast coast showed promising growth since 2012 — the first real glint of light since the dark and uncertain days of the northern cod stock collapse of the late 1980s and early 1990s. >click to read<10:10
