Farmers in the San Francisco Estuary have been using increasing amounts of weed killers, also called herbicides, on their farms. Herbicides kill unwanted weeds without hurting food crops. However, did you know that herbicides can hurt fish as well, especially those that live in the Estuary, like delta smelt? Delta smelt are small, translucent fish that only occur in the San Francisco Estuary. In the past, delta smelt could be found everywhere in the Estuary. However, they are currently threatened with extinction, largely due to human activities. In this study, we tested the toxicity of fluridone, a commonly used herbicide found in the San Francisco Estuary, on delta smelt. None of the fish died from fluridone, but we found that it weakened them, even after as little as 6 h of exposure!
