Mass Fish Die-off in Lake Cajititlan, Mexico

About 60 tons of fish die in Lake Cajititlan, Jalisco, Mexico

About a million dead fish washed up on the shores of Lake Cajititlan near the city of Guadalajara in Jalisco state, western Mexican, local media reported.

Officials say a wastewater treatment plant may have dumped untreated effluent in the lake thereby reducing the amount of oxygen in the water and suffocating the popoche chub freshwater fish.

In 2014, about 200 tons of dead popoche were removed from the lake.
