Baby sockeye salmon are growing faster due to climate change. Is bigger better?

Editor’s note: Most of the salmon on Cortes Island are Chum, not Sockeye, but a DFO study of scale growth measurements from the Big Qualicum River suggests Chum are also being affected by climate change. Chum salmon appear to be growing smaller ‘due to increased ocean temperatures driven by climate change‘ and also the increased competition over a diminishing number of prey. There are also reports of them relocating to more northern locations. In October 2023, a University of Alaska study revealed that 100 Chum had been found in waters emptying into the Arctic Ocean. They were ‘either actively spawning or had finished spawning.’ Lead author Peter Wesley wrote, “Throughout most parts of the salmon’s range, things have gotten too warm and they’re starting to blink off. In the Arctic, the water is getting warm enough and they’re starting to blink on.”

Climate change has tipped the scales, causing juvenile sockeye salmon in B.C. to grow bigger over the past century. 

The growth of salmon using lakes as nurseries during the first years of life in northern B.C. is about 35 per cent higher than 100 years ago, a new study from Simon Fraser University shows.

The past holds the key to the future for Skeena sockeye: SFU researcher

Editor’s note: This solution would not work for Chum, the principal salmon species found on Cortes Island. Unlike Coho, Chinook, and Sockeye, Chum do not reside in fresh water for an extended period. The 2022 and 2023 runs in Basil Creek were virtually wiped out because there was not enough water for them to return and spawn.

Comparing past sockeye populations in the Skeena watershed to their present-day counterparts may hold the key to preserving the species, according to an SFU postdoctoral fellow. 

Michael Price, who resides in Smithers, found in his Ph.D. research that a warming climate is making juvenile Skeena sockeye grow larger and is changing the habitats in which the young fish can thrive. 

Price found that small, warmer and more shallow lakes that juvenile sockeye used to thrive in are now becoming less suitable for the fish, with larger, deeper and colder lakes taking their place as the optimal habitat for sockeye to grow before they make the daunting trip to the ocean.

16 scientists condemn ‘scientific failings’ of ‘flawed’ DFO report

1 Comment

Editor’s note: The following article is joint letter to the Honourable Joyce Murray, Minister of Fisheries, Oceans and the Canadian Coast Guard

Academic scientists’ critique of DFO Science Response Report 2022/045

Dear Minister,

We are a group of 16 professors and research scientists who, collectively, have extensive research expertise in fisheries, epidemiology, and the environmental consequences of aquaculture. We write to express our professional dismay at serious scientific failings in a recently published DFO Science Response Report (#2022/045) about sea lice on salmon farms and wild salmon in BC. We are deeply concerned with the report’s flaws and its main, unsupported conclusion: that the presence of parasitic sea lice on wild juvenile salmon is not significantly associated with sea lice from nearby salmon farms.

Tensions rise as Coastal GasLink blasts a creek near a Wet’suwet’en camp

By Matt Simmons, The Narwhal, Local Journalism Initiative reporter

Less than one kilometre from a Wet’suwet’en camp and village site, where cabins, tiny homes and a feast hall provide space for ceremony, cultural practices and opportunities to reconnect with the land, is a vast muddy clearing, guarded by private security workers. 

Here, the path of the Coastal GasLink pipeline crosses Ts’elkay Kwe (Lamprey Creek), a tributary of Wedzin Kwa (Morice River). This work requires digging a trench right through the creek to bury the pipe under it.

Ts’elkay Kwe is a known spawning channel for steelhead trout trout and other species, including coho salmon, according to a 2007 land-use plan. But steelhead and salmon throughout the watershed are in decline, in part due to widespread clearcut logging and climate change.

Study Suggests Closing Fisheries for long term economic gain

1 Comment

By Matt Simmons, The Narwhal, Local Journalism Initiative reporter

At least a quarter of major fish stocks in Canada are in decline, but efforts to  rebuild them  — such as closing fisheries or setting catch limits — are  often met with strong opposition due to negative socioeconomic effects.  Now a new study by University of British Columbia researchers shows the  short-term financial pain can lead to long-term gain — and that pain can  be eased by providing fishers with social and economic assistance.
