ESTIMATING FLOW RATES TO OPTIMIZE WINTER HABITAT FOR CENTRARCHID FISH IN MISSISSIPPI RIVER (USA) BACKWATERS

摘要

The backwaters of large rivers provide winter refuge for many riverine fish, but often exhibit low dissolved oxygen levels due to high biological oxygen demand and low flows. Introducing water from the main channel can increase oxygen levels in backwaters, but can also increase current velocity and reduce temperature during winter, which may reduce habitat suitability for fish. In 1993, culverts were installed to introduce flow to the Finger Lakes.
