Everyone has a different perspective about what it means for humanity to live harmoniously with all the other life we share the planet with. I think it’s fascinating how those ideas and endeavors trickle down through engineering into the real world.

Aerial fish stocking does work, at least in certain circumstances. In Utah high elevation lakes that are inaccessible to trucks are routinely stocked from the air with very small trout. The fish are usually less than 2" in size and survival is well over 90%. Obviously a larger fish would just go splat, but the little ones almost float down like leaves.

Surprised you didn't include the Ballard Locks in Seattle while you were up in the PNW. Its an interesting example of a fish ladder that exists at the fresh/salt water boundary, and it mostly serves salmon descended from ones that were introduced by humans to replace runs we destroyed in the process of diverting rivers to construct the Ship Canal and locks. There's a publicly accessible viewing window near the top of the fish ladder if you are there during the migratory period, and the surrounding site hosts a small botanical gardens. Plus, the boat locks themselves are pretty interesting to anyone watching this channel!

@birdrocket Місяць тому
It’s fascinating that fish ladders are seen as essentially necessary for dams due to the fragmentation of their habitat, but the vast majority of roads through wild areas have no such consideration for wildlife. Habitat fragmentation from roads is an enormous problem, the book “Traffication” is all about how roads have destroyed natural habitats and created pockets of gene pools that don’t cross those roads.

@@a2e5 unfortunately that’s only a small subset of the problem. Large animals like deer might cross a street, but smaller slower animals might not make it across, and many don’t even try, keeping them locked in a tiny genetic pool that is the island of wilderness locked in by roads on all sides

Made me so happy to learn more about fish ladders from an engineering perspective!
@ars85202 14 днів тому
That's true and your PhD thesis sounds interesting, I have wondered myself about those impacts from the beginning of the video. I would add that, as a social scientist, one of the most important thing I can do is question whether or not our "human needs" are really needs for the working class and not just wants from the ruling class, and what are the real needs of the working class. One example is how the car and oil industries lobbied for car-dependent cities, creating an artificial need for their products at the cost of the working class. From the words of Chico Mendes, a Brazilian conservationist and climate activist, "ecology without class struggle is just gardening"

I've had the opportunity to visit the St Stephen fish lift in Berkeley County, South Carolina. It's impressive. The people that run that thing do a fantastic job and help greatly with conservation. Hundreds of thousands of striped bass and American shad swim through it each year and spawn. If any of you guys are ever in the area when the fish are running and ever get the chance to tour it I recommend it. They have viewing windows in the fish lift so you can see the fish swimming through it.

fun fact: with washington state, we love our hydroelectric dams (with understanding on my end) which also makes to understandable with fishway/ladders to be put in the designs of the state dams

In Sacramento, there’s a fish hatchery by the American River right before the Nimbus dam (a downstream dam off Folsom Lake). In the hatchery, they rebuilt the ladder with glass windows, so visitors can actually see the chinook salmons and steelheads. If you’re in the area, or just passing by to/from Lake Tahoe, go visit the Nimbus Fish hatchery.
