I’d like to invite you to Freshwaters Illustrated’s WaterNight, Wednesday, March 18. It will be an online celebration of Freshwaters Illustrated’s incredible movies and photos featuring freshwater habitats of all kinds & stories from the people who care for them.

Kurt Fausch has a new book out now (just ordered my copy) about developing an ethic for rivers. I was a huge fan of Kurt’s first book, For the Love of Rivers (I bought copies for everyone in my immediate family), and I’m maybe even more excited to read A Reverence for Rivers.

@amfisheriessoc.bsky.social are there any plans to push back on the current pause in NSF grants, threats to fish through undercutting the CWA & other potential changes in land management? How about the attacks on DEI in science?

Anyone else have a strong, visceral negative reaction to bar charts (other than when used to show proportions)? Just me? I always feel like someone’s trying to hide something from me when they use a bar chart.

I wrote up a summary of Seals et al. 2024 for my nonprofit’s blog. The big take-away: in the Deschutes River, wild fish make up around 65% of steelhead caught in the recreational fishery, even though they’re only about 30% of the total run. nativefishsociety.org/news-media/d...

Mirror life, synthetic cells, transgenic organisms, de-extinct species, and functionally distinct nonnative species can all be classed as 'novel biological entities' (those with no analogue in the envt in which they are released) and pose unique biosecurity risks. www.theguardian.com/science/2024...

Redbands also tend to do better in warmer temps than their coastal counterparts and are more resistant to C. shasta infections. The adfluvial Redbands in the upper Klamath can be as big as steelhead!

Big thanks to @mekka.mekka-tech.com for spotlighting this article in his thread on what police actually do, and why the NYPD’s slapstick performance after the UHG CEO shooting was not at all surprising. We Minneapolitans have really got to get this evidence into the city’s political conversation.

Police are not primarily crime fighters, according to the data
A new report adds to a growing line of research showing that police departments don’t solve serious or violent crimes with any regularity, and in fact, spend very little time on crime control, in contrast to popular narratives.

Super excited that this amazing book is finally available for preorder. It was written by over 50 Indigenous Peoples from around the world and contains stories, poetry, and critical thought pieces on how TEK is used and extracted from our communities and what folks are doing to protect it.

Alaska used to be one of the few remaining strongholds for wild Pacific salmon. But Alaska's wild salmon can no longer withstand annual releases of billions of hatchery pink salmon, degrading ocean conditions (i.e. marine heatwaves) and destruction of the marine ecosystem from industrial trawling.

For a number of years now, I’ve had a policy that I don’t submit to nor will I review for MPDI and Frontiers. This analysis supports that decision. It’s no reflection on the many excellent papers and studies that have been published in them, but rather on their editorial and business practices.

This is something that has galled me for a while—folks talking about rivers as if they were just conduits of water & materials to the ocean and not complex, dynamic ecosystems in their own right.

Giving Bluesky a chance for connecting with other freshwater/fish folk. I’ve studied how artificial light at night affects river & riparian ecosystems, but these days do advocacy and focus on how fish respond to restoration, dams & angling.
