LOUISIANA ESTUARINE AND COASTAL FISHERIES AND HABITATS: PERSPECTIVES FROM A FISH'S EYE VIEW

Stimulated by nutrients from the Mississippi River, the vast coastal wetlands of the river's past and present deltas interface with the Gulf of Mexico to form a complex and prolific marine ecosystem. This highly productive system has yielded annual fishery landings of >453.6 × 106 kg (1 billion pounds) since 1969. The Louisiana ecosystem has been heavily exploited and significantly altered over the years to meet the demands for coastal development, seafood production, navigation, oil exploration, flood control, and other social, economic, and industrial activities. While not all impacts can be viewed as detrimental to fisheries or their habitat, some of these habitat impacts have contributed to significant ecological problems such as saltwater intrusion, loss of coastal wetlands, and development of vast areas of hypoxia along the coast. Management strategies to deal with some of these problems propose directed manipulations of the coastal environments to stop or reduce rates of degradation. Over the past ...
