Rebuilding key forage fish stocks for healthier East Coast fisheries

- Advertisement -

OTTAWA, ON, March 30, 2022 /CNW/ – The long-term prosperity of Canada’s seafood sector depends on abundant fish stocks and healthy ecosystems. In Eastern Canada, pelagic forage fish, like herring and mackerel, play a vital role in the ecosystem and the fishing industry. They are an important food source for other species, including tuna and Atlantic cod, and are a traditional source of bait in some commercial fisheries, including lobster and snow crab.

Southern Gulf spring herring and Atlantic mackerel are two stocks that are in the critical zone. Urgent action must be taken in the short-term to give these stocks a chance to recover and ensure the long-term sustainability and prosperity of East Coast fisheries.

Today, the Minister of Fisheries, Oceans and the Canadian Coast Guard, the Honourable Joyce Murray, announced there would be no directed commercial or bait fishing for southern Gulf spring herring and a closure of the Atlantic mackerel commercial and bait fisheries in Atlantic Canada and Quebec.

During the past several years, Fisheries and Oceans Canada has put many management measures in place to help rebuild these two stocks:

  • For southern Gulf spring herring, Fisheries and Oceans Canada implemented daily catch limits, minimum mesh (hole) size in nets, limits on overall size and number of nets, dockside monitoring of catches and weekend fishing closures.
  • For Atlantic mackerel, Fisheries and Oceans Canada implemented catch reductions over time, an increase to the minimum allowable size, and reporting improvements. In addition, new regulatory amendments came into force in 2021 that set a daily possession limit of 20 mackerel per person when fishing recreationally, established a minimum possession size of 26.8 cm, and closed the recreational fishery from January 1 to March 31 every year.

Unfortunately, these measures have not been enough. Under Fisheries and Oceans Canada’s Precautionary Approach Framework, when a commercially-fished stock is in the critical zone, removals from all sources must be kept to the lowest possible levels. Reduced fishing pressure may help these stocks to mature, reproduce and rebuild.

Fisheries and Oceans Canada is committed to supporting the future opening of these commercial and bait fisheries. The closures will be revisited following the next stock assessments.

As some pelagic forage stocks have been in decline for several years, many harvesters have already begun sourcing bait from elsewhere or using alternative bait. Fisheries and Oceans Canada has invested in projects that support more sustainable, alternative bait. 


“We know more than ninety per cent of fish stocks on the East Coast are in good shape and I am committed to working with industry to grow the very important fish and seafood industry. Southern Gulf spring herring and Atlantic mackerel are stocks that have been in the critical zone for lengthy periods and need to be allowed to regenerate for the continued sustainability and success of the entire fishery. I recognize many harvesters depend on these fisheries. I will continue working with them and fishing groups from across Atlantic Canada and Quebec to ensure the best outcomes for these stocks and the people who depend on them.”

Quick Facts
  • Food, social and ceremonial fisheries for First Nation communities will remain open for both southern Gulf spring herring and Atlantic mackerel. The recreational fishery for mackerel will also remain open, applying the daily limit that was put into regulations last year.
  • Southern gulf spring herring has been in a critical state for 20 years. Recent stock assessments for southern Gulf spring herring show that several factors have likely contributed to its decline, including changes in environmental conditions, predation by other species, low recruitment (or the survival and development of larvae) and fishing. A rebuilding plan is currently in development for spring herring.
  • Atlantic mackerel has been in or near the critical zone for more than 10 years. According to the 2021 stock assessment, fisheries are capturing younger fish, which need more time to grow and spawn in order to support a healthy population. A Rebuilding Plan for Atlantic Mackerel is posted online and will be updated to reflect the 2021 stock assessment and new management measures in 2022 to support stock rebuilding.
