Fishermen frustrated after DFO extends gulf herring moratorium by 2 years

Scientists say there are no signs that the Atlantic herring stock is improving, but some fishermen aren't convinced. 

Fisheries and Oceans Canada placed a moratorium on herring fishing in the Gulf of St. Lawrence in 2022, saying urgent action had to be taken to give the stocks a chance to recover. 

Three years later, DFO said that recovery hasn't happened, prompting the agency to keep the fishery closed through 2026. 

"The stock status is currently very much like it was the past few years," said Jacob Burbank, a research scientist with DFO. "The stock is still in the critical zone, and it has been in the critical zone since the early 2000s."

Several factors could be to blame, said Burbank, like warming waters and a reduction in the amount of available foods like zooplankton. The herring also aren't growing as large, and they're producing fewer eggs. 

Herring plays a vital role in both the fishing industry and ocean ecosystems. It's an important food source for other species, including tuna and Atlantic cod. 

They are also a traditional source of bait in many commercial fisheries, including lobster, snow crab and halibut.

The extension of the moratorium has left harvesters to rely on other sources of bait like mackerel, redfish and some manufactured products. 

But those often come at a higher cost, said Ian MacPherson, the executive director of the P.E.I. Fishermen's Association.

The industry on the Island is disappointed with the decision to extend the moratorium, he said. 

"There's no win anywhere if the stock's not protected and taken care of, so we're all on that page," MacPherson said.

"One of the things that tends to happen, though, when a species is in a moratorium is a lot less science gets done. So there could be positive changes out there that aren't getting picked up." 

He said, anecdotally, fishermen have been seeing more herring when they're out on the water. 

The association had hoped to partner with DFO on what's known as a scientific fishery, where fishermen collect a reduced catch of herring and report back on the stock's health to scientists.
