More research is needed on the seal population’s impact on dwindling East Coast fish stocks, federal Fisheries Minister Joyce Murray said Thursday, in response to a report by the region’s fisheries industry.
Part of that research will include a summit in St. John’s this fall on the country’s seal population, Murray said, reacting to the newly released report from the Atlantic seal science task team, which was commissioned by the Fisheries Department in 2020.
The report said the high numbers of grey seals and harp seas “are at or approaching historic levels” and are having a “serious impact on the ocean ecosystem in Atlantic Canada.
“The extent of the impacts cannot be determined with the limited information held by DFO science.”
It said the grey seal population in Atlantic Canada has increased from around 15,000 in the 1960s to 424,300 animals in 2016, which is the largest concentration of grey seals in the world. The region’s harp seal population has increased from approximately two million animals in the 1970s to an estimated 7.6 million in 2019, and it is the largest Northwest Atlantic harp seal population in recorded history.
Groundfish stocks in Atlantic Canada, the report said, “are at or near the lowest level ever observed and are experiencing very little recovery due to very high levels of unexplained natural mortality, which has been attributed to seals in some regions, but not in other regions.”
Commercial finfish fisheries, it added, “are at an all-time low,” which is being driven in party, by “unexplained natural mortality.”
Glenn Blackwood, the report’s co-chair, said the mortality rate for many fish stocks is high, adding that the region’s fishing industry and the Fisheries Department need to know what role seals are playing in the ocean ecosystem.
“Additional work needs to be done on harp and grey seal feeding,” Blackwood told the news conference. “Also on distribution patterns, and we need to understand the relationship of seals to fish stocks.”
“We believe that industry is ready to step up and work with DFO science on designing, collecting the samples and solving this problem,” he said.
Speaking outside a seafood processing plant, Murray drew applause when she said she knows “seals eat fish.”
“So, that’s the reason we need to better understand the impact they are having on our fish stocks,” she said. “The task team has delivered a report that starts the conversation on how we can move forward to address the concerns we’ve heard from harvesters about this simple fact.”
The minister said that as a first step, her department will host a seal summit this fall. “That will be to broaden engagement on Atlantic seals and bring stakeholders together to discuss approaches for science, market development and management,” she said.
Murray said her department is committed to maintaining the existing markets for Canadian seal products and supporting the development of potential new markets.
