New study documents BP oil's impact on common baitfish in Gulf

A new study published in the Proceedings of the National Academy of Sciences documents the effect of BP oil on Gulf killifish, a minnow-like wetlands fish, also known as bull minnow or cacahoe. Killifish are a critical part of the Gulf’s food chain and are a commonly used baitfish. Oil exposure has altered the killifish’s cellular function increasing developmental abnormalities, decreased hatching success, and decreased embryo and larval survival. Land Tawney, senior manager for sportsmen leadership with the National Wildlife Federation said even small amounts of oil can have a lasting impact on fish, wildlife and habitats. Learn more at
