Experiencing first hand the pink salmon migration in Norway 👇👀 Nearly 8000 caught in a net sweep at Syltefjorden, Finnmark, July 2023 🇳🇴. Incredible work by local communities to try to remove this alien species before spawning 💪

Interesting piece and article on potential for (mis)management of invasive species. Highly relevant to the conversations on #invasive #crayfish control here in the UK e.g. why top down 'eat to beat' won't work theconversation.com/invasive…

Invasive species: why Britain can’t eat its way out of its crayfish problem

We found that signal crayfish traps tend to catch larger males, letting the bulk of the population go free.

New research suggests that sometimes trying to completely eliminate a problematic non-native species may cause more harm than good.

Two birds one stone - or rather, one trap many species! Really pleased to share the second paper from my PhD work, showing that Pritchard Traps can quantitatively survey benthic fish as well as crayfish! #novelmethod #electrofishing #benthic #fish #newpaper #phdchat

So unbelievably excited to see this yesterday. These are standard Alder cones. I noticed that many of them had red and yellow water droplets. After talking with @LeifBersweden and @PinkfootedGus we think this is the Tannins in the cones that have stained the water! Astounding.

Can we eat invasive species to death? Unlikely in general. Human consumption alone probably won't wipe out populations of very prolific invaders. Moreover, turning an invasive species into an economic resource could encourage its cultivation & spread. theatlantic.com/science/arch…

The news story here, which the BBC for some inexplicable reason have buried in the article, is that 88% of Tory ads were found to misleading, compared to 0% for Labour. The Tories are objectively running a campaign of lies bbc.co.uk/news/amp/technolog…
