The phenomenon is known as a “fish kill” and can occur naturally in warm summer weather, according to Texas Parks and Wildlife. | Local officials also said that the ocean had been calm over the last few weeks, meaning there were fewer waves to distribute oxygen, and that the past few days had been cloudy, leading to less photosynthesis from oxygen-producing phytoplankton.
