Hopefully they have a DNA sample somewhere. What a shame.
I was just thinking, are there any initiatives in long term DNA storage of extinct or endangered species?
Then there might at least be a chance to bring them back one day?

Perhaps because that title completely omits any form of attribution, which as the article suggests, is largely because of the Gezhouba Dam which completely cut paddlefish off from their only spawning grounds. Why would you want to omit that part? That said, this title is a poor attempt at communication.
Well now you have a title that's, to me, incomprehensible
It's not just you - the new title makes no sense at all to me either. It reads as a jumbled collection of random words :/

#33Serious question here - not starting a flamewar. Are there any real organizations in China with power that protect the ecosystem and animals there? From an outsider it seems like they just build whatever they want without any concern for the environment they live in which ultimately will do significant damage to their own human population after the environment collapses and can't support them.
Note that this dam was built in 1970, when no-one was worrying too much about the long-term consequences of dams.

The whole article is talking about China attempts to preserve endangered fish species. It mostly talking about how in the 80 and 90s they didn't do those preservation research when building dams. The article also talks that its not only happening in China these old paddlefish species are endangered all over the globe.
> The article also talks that its not only happening in China these old paddlefish species are endangered all over the globe. What remarkable a looking fish, it looks more like a shark with a very elongated nose. Well, pat-on the-back progress aside of their 'efforts', I feel that this is in-line with not just the CCP's outview on the World, but Humanity in general. Biodiversity be damned (no pun intended) if it stan…
Just last summer there was major flooding up and down the Yangtze. It used to be that lots of people died from these events, now that they have the river under control it's fine.
Calling it simply 'development' obscures the very real human benefits.

#37> This dam, which was constructed without a fish ladder or bypass, cut off the paddlefish from their only spawning grounds upstream, which had only been discovered in the late 1970s.
How effective are fish ladders? If they’re effective, shouldn’t we focus on building a fish ladder on all existing dams?

#39Why can’t they split the river in multiple parts with a small tributary for wildlife that meets up with the rest of the river downstream? https://en.m.wikipedia.org/wiki/River_bifurcation
When the dam was built, they didn’t know they were cutting off the fish from it’s only spawn point in the world (it was discovered later).
Still, there’s an argument to be made for building a bypass or fish ladder in every single new and existing dam regardless of what the current expected impact is.
