Extreme heat causing toxic algae growth. Heavy winds cause the algae to mix in the water killing fish. Or the algae uses up oxygen in the water at night suffocating the fish. The link where this story was posted in Campfire has the first explanation I believe. And yes, it smells horrible

...more like, Holy Tilapia. Looks like the tilapia are doing some successful spawning...makes you wonder how the corvina are doing.

I was talking to Randy at Wister last week. He does the quarterly fish counts at the Salton Sea. Absolutely no corvina in the sea. I think he said it was for the past 3 years it's been like that. The tilapia is making a huge comeback, but no corvina. I asked him if he meant none as is "nothing of significance" or "zero" - he said "zero".

That's too damn bad. I hope there's a population of corvina tucked away in some corner of the Sea, eating tilapia, getting fat, and spawning like rabbits.

You may throw that theory out.
Algae are photosynthetic (i.e.plants), which use light and CO2 to produce oxygen.

Actually, the algae dies and the decomposition causes the oxygen depleation.

At night plants switch over to resperation and consume oxygen. As well decomposition of dead organisms consumes a massive amount of oxygen. When you treat for aquatic plants you have to do small portions of a body of water at a time usually less than 25% to avoid decomposing plant matter from consuming all the oxygen.
