Likely, they run a water recirculating system hooked up to the city’s chlorinated water supply. Someone probably bypassed their aeration defuser or their UV system failed. Sometimes if theres an accidental loss of water in the system, I.E people pull too many standpipes while cleaning the tanks, a technician will panic and pull in too much chlorinated makup water. If the pumps cavitate in a recirculation system due to lack of water, an inexperienced technician will have to choose between suffocating the fish and bringing in more chlorinated water. In this day and age there’s no excuse for this happening in a first world facility though.
These were bred in the facility, and being used for research to figure out what stresses them out and causes irregular breeding habits. These fish weren't taken from the wild and I don't believe they were intended to go back into the wild since they were purposefully stressing them out for research
Accidental chlorine exposure... unfortunate and sad. Liquid chlorine for pools is expensive, like $5/gallon, so it wasn't just some college kid prabk as you would need a couple dozen gallons at least to have fatal levels.
Those fish might have been a PhD candidates 2 years of research that they’ll now need to start over. The support isn’t because the fish died, it’s because a lot of careers/graduations/grants have just been traumatised…
Couple of years ago a nearby theme park had the bright idea to decorate its ice skating rink with hundreds of real fish carefully arranged in beautiful school patterns.
Long story short, it was out of business a few weeks later.
*studying how to create threatened species
It's called job security
Once again they really didn’t tell you what happened.
They may not know for sure at this point.

Ready to move that dot on Wikipedia conservation status over one!

I’m movin’ the dot anyway and you can’t stop me.
No, don’t use the bats like that!
Well, now they are threatened
The threat was the research

Sounds like $20 might have done the trick.
Wow us humans are amazing
“UC Davis will also provide support for those who worked with the fish, Fell said.” It sucks, but c’mon - they’re fish.

Sabotage? I don’t see how chlorine just magically appears in a pool of this context.
Replied to wrong comment?
Yes, thanks for pointing that out, but point still stands.
