Where did my fish go?

[Gourmandise]

I was watching something somewhere (very informative, I know) and it was said that around 70-80% of the fish in the ocean are gone. The jellyfish population has risen too, making the ocean more acidic and bad(?).
Is this true. Ever since hearing that I have not had fish and I don't want to. It's a shame too, I love tilapia.

They left before the Vogons arrive.

I think tilapia are fresh water fish. They use them in fish farms a lot.

Well my day has been made in a minor way. I still feel for the lack of other fish.

No true estimates on population loss, but with increasing ocean temps from climate change and sea level rising, coral reefs die off since they do not have proper access to light levels needed. The hotter the sea gets the more carbon dioxide is released which causes algal blooms and explosions in jellyfish populations. The seas are becoming more acidic and this causes corals, starfish, mollusks and crustaceans(calcium based exoskeletons) to die off, in some causes due to literally being dissolved (look up coral bleaching). With reefs dead the whole population that needs them for survival die off along with anything larger that requires the fish to feed on.

So it's not straight up overfishing

It is, however, straight up humans' fault, any way you look at it. Overfishing, pollution, warmer sea temperatures. All our fault.

My scheme to not eat fish is only a band-aid then...
I guess I have to mind control the world into not hurting da earf

80% of all fish? No, that's impossible considering that an absolutely massive portion of them (deep sea) aren't fished, aren't able to be monitored and most of all, we have no clue what the fuck goes on down there. Not to mention that something like 95% of life down there is unknown/undocumented to any significant extent.

That said, even an 80% decline in upper sea level fish sounds completely unreasonable, that kind of loss would have lead to extinction for most types of fish already. 80% drop on certain species? Now that's plausible.
