Comparison of Bowfin Diets in the Upper Barataria Estuary and Atchafalaya River Basins of the Lower Mississippi River

SEAFWA Journal Volume 8, March 2021

The life histories of many organisms are directly tied to floodplain inundation for access to spawning grounds, nurseries, and feeding, but many floodplain ecosystems have been altered by anthropogenic activities and are disconnected from associated rivers. The Atchafalaya River Basin (ARB) floodplain, Louisiana, is relatively intact, whereas the upper Barataria Estuary (UBE) has been separated from the Mississippi River by anthropogenic modifications and lacks an annual flood pulse.
