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!

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 26 дней назад

In a good number of places, wildlife bridges / underpasses can now be economically justified by the cost of car-animal crashes. Sad, but at least it gets them built.

@birdrocket 26 дней назад

@@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

@ars85202 17 дней назад

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 was watching a documentary about the River Danube last night. Apparently the Iron Gates Dam has had a catastrophic effect on Beluga migration and so caviare production. It must be difficult designing a fish ladder for something the size of a beluga.

As a fish, such efforts are much appreciated

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

I love the fish model at around 5 minutes, very realistic.

Machine learning with a camera on that window would be a very cool project.

I love these! As much as a tragedy the bridge in Boston is, it too will be a great engineering challenge I hope to see on here some day

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.
