Interestingly there is a term for the last known member of a species: Endling [1]. Scrolling through that Wikipedia article always gives me an eerie feeling. It looks like the Chinese paddlefish is not listed yet though. [1] https://en.wikipedia.org/wiki/Endling

Last time similar topic came up (either here or reddit), someone posted this recording of a ”Kauaʻi ʻōʻō” bird [1] in which a male, apparently the last of its species, is trying to connect with a female. Reeally eerie.

On some bright news. Thanks to declining American manufacturing (thanks China) The Detroit River has bounced back. Giant 'river monster' fish found in Detroit River may be over 100 years old https://www.cnn.com/2021/05/07/us/sturgeon-fish-intl-scli/in...

> Thanks to declining American manufacturing (thanks China) Spoken like someone who doesn't work in manufacturing...

(I'm not American so don't really have a horse to grind or axe in this race, but) why would an American working in manufacturing want American manufacturing to decline? Or do I misunderstand?

Earlier quoted context omitted.

Do you maybe mean something like a fish ladder? https://en.wikipedia.org/wiki/Fish_ladder

Or the cool "Salmon cannon" https://www.youtube.com/watch?v=2z3ZyGlqUkA

Am I seeing that right, they have a guy stand there, pick fish up, and load them in to a pressurised cannon?

I wad expecting something a bit more sophisticated/under the fish's control, even given the name!

Thank you. The article notes that other pressures such as overfishing also contribute to the decline of fish populations, and that fish ladders on the Columbia river are successful.

No doubt there are some ineffective fish ladders out there, and no doubt dams have a negative impact on fish populations. Could better designed fish ladders and compensation channels mitigate the effect of the dam? I think so.

Fish stocks across all species are collapsing due to overfishing.

This shit always just makes me so incredibly, deeply sad. It's the loneliest thing I can imagine.

> Furthermore, activities like fishing and dam construction deserve more scrutiny The Gezhouba Dam generates 2.7 GW of carbon free power. In the light of the critical nature of climate change, we need to build more dams like it if we can. Even if a few species on the go go extinct, compared to the massive devastation that will happen from climate change, that is still preferable. Climate change is an emergency, and w…

You first.

Padlefish and Baiji dolphin river. Both went extinct at the same time by the same dam. 2003 and 2007. Our time. The "Las Vegas Frog" have a stroke of luck, but it is always the same history And the californian vaquita is probably extinct yet.

I had never heard of the California vaquita. Google revealed:

"The tiny vaquita porpoise is the world’s most endangered marine mammal. Its numbers are decreasing with fewer than 19 remaining. Vaquitas die from entanglement in illegal gillnets which are intended to catch totoaba, in a lucrative illegal fishery that serves an illegal trade of swim bladders to China."

The unbridled enthusiasm of man again pushes us deeper into this 6th mass extinction event, the Holocene extinction https://en.wikipedia.org/wiki/Holocene_extinction . I still remember the Baiji https://en.wikipedia.org/wiki/Baiji or the finless porpoise https://en.wikipedia.org/wiki/Narrow-ridged_finless_porpoise . Can we realistically ever taper down and live more simple minimalistic lives that strike a better bala…

This ain’t a mass extinction yet
