Fish movement and predation on macroinvertebrates in a lakeshore marsh / George David Lapointe.

TextSeries: Thesis. (M.S.)Publication details: Minneapolis, MN : University of Minnesota, 1986.Description: vii, 88 leaves : ill. ; 28 cmOnline resources: Abstract: This thesis consists of a preface and two papers. The objectives of paper one were 1) to describe fish movement between Lake Manitoba and the Delta Marsh, Manitoba; and 2) to use this fish movement information to make recommendations to minimize impacts of a waterfowl habitat management plan on fish populations. Fish movement was studied in 1983 using fyke nets on Cram Creek in Delta Marsh. Weather conditions prevented sampling on one-third of the days from 3 May through 27 August. As a result of this variable sampling effort, only general trends in fish movement were observed. Common white sucker, northern pike, yellow perch, and carp each had over 200 fish caught. Bullhead,burbot, lake herring, quillback, sauger, and walleye each had over 20 observations. The major impacts on fish of waterfowl habitat management strategies were discussed. The amount of marsh area available to fish would be reduced during drawdowns. Early season control structure closure would prevent fish movement
