So everyone knows that northern cod collapsed completely in the 1980s and never recovered. Well... it's actually kind of recovering now. Spawning biomass is at pretty good levels, while catches remain at a tiny fraction of the heyday levels.

NOAA proposed budgets would eliminate science and management of marine mammals and sea turtles, firing 311 scientists and cutting the budget by more than $100m. Also a long list of program terminations...

This is interesting. We have a similar study ongoing but looking at Dolly Varden! Thanks for the reference!

"If the United States no longer wants to lead, Canada will."

This is what real leadership looks like.

It’s
Going to be an exciting year with the installation of a Full duplex directional PIT tag array.

We’re going to be estimating in-river and marine survival, evaluating close-kin mark recapture as method to estimate spawning stock size!

Huge thanks to @hctfbc.bsky.social for agreeing to fund the expanded breadth of monitoring and research we are doing for steelhead, cutthroat trout, coho and Dolly Varden at the Keogh River, Vancouver island for 25/26.

Elon Musk is a proven danger to good science, but the Royal Society won’t say so. That’s why I resigned | Kit Yates It is vital to act, and I urge colleagues to do so. How can we stand by and laud this man while he undermines scientific integrity? asks academic and author Kit Yates

🚨I promised I'd say more on the Royal Society and Elon Musk, so here it is. 🚨

I've resigned my position as Associate Editor at Royal Society's journal Open Science in protest at their lack of action over Elon Musk.

Trudeau: "I want to speak first directly to the American people. We don't want this. We want to work with you as a friend and ally. We don't want to see you hurt either. But your government has chosen to do this to you. As of this morning, markets are down and inflation is set to rise dramatically."

At our research site we used STARLINK for data transmission. We’ve decided to cancel and move to cellular.

Not worth the uncertainty it may get cut off without notice and the fascism free service will also be nice!!

I don't know who needs to hear this today, but our lab's new website comes equipped with a "Carc Gallery" (a collection of photos of salmon carcasses that died of natural causes, after spawning).
