Low pH Levels Can Eliminate Harmful Blooms of Golden Algae, One Cause of Massive Fish Kills




 Baylor University researchers are one step closer to understanding the algae that causes a substantial number of fish deaths in more than 18 states.

Golden algae, Texas Tide or Prymnesium parvum, as it is known by its scientific name, produces toxins that can severely impact aquatic organisms. Over the past decade, golden algae blooms have been responsible for the death of tens of millions of fish in Texas reservoirs.

Bryan W. Brooks, Ph.D., professor of environmental science and biomedical studies at Baylor and director of the environmental science graduate program and the environmental health science program, and his research team found that neutral pH levels prevented the algae's bloom development and the toxicity of the algae was greatly diminished.
