Elated to See Coho Spawning in Byrne Creek in Burnaby

Yay! Saw a pair of spawning Coho salmon in the lower ravine today.

We’ve been getting so few spawners back that this is a wonderful sight to see. Especially with Coho, since many of the few females that come back to our creek die before spawning.

I spotted the female first. You can see her white, abraded tail, worn down from digging her redd (nest for her eggs). And you can see the redd, the bright patch of cleaned gravel and cobble.
I suspected there must be a male nearby, and then the female spooked and ran about 10m d/s to hide under a log. I took another quick look, not wanting to disturb her again, and was elated to see the larger, wine-dark colour of a male beside her!

Updating Quake/Go Kits, Car Kit

Taking a lesson from the flooding and refreshed our quake/disaster Go bags today.

They are backpacks that we keep at the front door with changes of clothing, rain jackets, toques, heavy socks, mittens, emergency sleeping shelter (a reflective sleeping bag that weighs a few ounces), flashlights, extra batteries, granola bars, chocolate, water, Life Straw personal water filter, fixed-blade knife with a fire-steel in the handle, first aid kits, etc. . .

His and hers.

Oh, yeah, also a Zip bag full of cat food and a small carrier.

We also keep some gear in the car at all times, but I should probably upgrade that. . . So I just ordered some emergency gear to update the quake kits and pad the car kit from Mountain Equipment Company.

Byrne Creek Patrol for Spawning Salmon in Burnaby, BC

Volunteers patrolled Byrne Creek in SE Burnaby, BC, today for spawning salmon. It was a good count for our little urban creek, but unfortunately we are yet again seeing Coho prespawn mortality.

This means that Coho die before they spawn, and the first female we found this year was dead yet full of eggs. This issue has been studied in Washington State, and the smoking gun is a chemical in tires that washes off roads and into creeks. For some reason it kills Coho but Chum are not affected.

We get so few Coho back every year that each unspawned female is a small tragedy.

Today’s count below. . .
