Hundreds and thousands of dead fish have been washed ashore on the banks of Mexico’s Cajititlan Lagoon over the past week.
Local wastewater treatment plants could be responsible with mud from the plants reducing oxygen levels at the bottom of the lagoon. An investigation is underway.
The local fishermen’s cooperative leader Martin Morales says its a disaster.
“I think that the evidence highlights that the pollution in the lagoon is getting worse and I believe the authorities must do something.”
The small Cajititlan Lagoon which lies in Jalisco State provides a vital living to many local fishermen and their families.
The local authorities say the dead fish are a natural phenomena but environmentalists point to poor management of the lagoon.
