The Mississippi River (MR) is severely regulated, mainly for transportation and flood control. Coastal wetlands are critical to marine fishes and invertebrates, and about 0.6% are being lost yearly to natural and human-induced forces, including levees which divert sediment directly into the Gulf of Mexico, instead of allowing it to build up the delta during annual floods. Distribution of 241 fish species reported from mainstream MR has been influenced mainly by glaciation, natural barriers and human activities; species diversity generally increases downstream.
