Abstract

Crappie ranked second in the creel of Iowa anglers and is particularly important to those who fish large flood control reservoirs such as Rathbun Lake. This investigation determined the environmental factors that influence the abundance of young crappie and how these factors, in addition to angler harvest, impact the crappie fishery. Young crappie survival, measured over a 22-year period, was affected greatly by water level. A positive relationsh1p existed between density of young crappies and water storage in acre-feet days, measured in April-August.
