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
Small shrimp biomass increase off Newfoundland’s northeast coast
The latest news about the state of the northern shrimp stock in key Shrimp Fishing Area 6 off the province’s northeast coast is a bit more uplifting this year than about the same time last year. Last year the news was grim — this year, although the shrimp stock remains listed in the critical zone, the fishable biomass has increased by three per cent between 2017 and 2018, and there’s a 27 per cent increase in spawning stock biomass between 2017 and 2018. >click to read<19:33
