From Mississippi Sportsman:

A Louisiana paper mill admits discharge caused massive Pearl River fish kill “The company said it believes that an “exceedence” of discharge above the level for which it is permitted depleted the river’s dissolved oxygen levels, leading to the kill that began on Saturday…”

Note that one repeat commenter on this story still claims that the fish kill is due to “summertime heat” even after the mill has claimed responsibility.
