A species of tiny fish that once flourished in a river running hundreds of miles from central Mississippi into southeastern Louisiana is being reintroduced to the Pearl River after disappearing 50 years ago.
Wildlife experts say a number of factors likely contributed to the disappearance of the pearl darter from the Pearl River system, including oil and gas development, agricultural runoff, urban pollution, and dam construction. All are deemed detrimental to the pearl darter's habitat and survival.
