Texas Beaches Suffer Massive Fish Die-Off.

Tens of thousands of dead fish washed up on the Gulf coast of Texas over the weekend, covering the shoreline with rotting carcasses and leading local officials to warn visitors to keep away. Low levels of dissolved oxygen in the water made it difficult for the fish to breathe, Texas parks and wildlife department officials said. The phenomenon – known as a “fish kill” – is common as temperatures rise in the summer, the state department said. Gulf menhaden, which fishers commonly use for bait, was the species most affected in the kill, parks and wildlife officials said.
