Without rain, the river “will continue to empty. And yes, all fish will die. … They are trapped upstream and downstream, there’s no water coming in, so the oxygen level will keep decreasing as the (water) volume will go down,” Couasné said. “These are species that will gradually disappear.”

How do droughts affect fishing?

How do droughts affect rivers?
More frequent droughts and shifting precipitation patterns lower water levels in rivers, lakes and streams, leaving less water to dilute pollutants. Higher temperatures cause more frequent algal blooms and reduce dissolved oxygen levels, both of which can cause fish kills and do significant harm to ecosystems.

Can fishes feel pain?

Why do fish continue to move after death?
