Ecological performance of red drum ( Sciaenops ocellatus ) larvae exposed to environmental levels of the insecticide malathion
Abstract Malathion is a highly soluble or ganophosphate insecticide that is widely used in agriculture and mosquito eradication campaigns. Fish species, such as red drum ( Sciaenops ocellatus ), that use seagrass beds as nursery areas could be affected by runoff waters contaminated with malathion. W...
