rime real estate for residences and recreation, but this development comes at an ecological price. Two studies to be presented at the ESA meeting offer new insights into determining how lakeshore development impacts sport fish populations.
Van Butsic, David Lewis, and Volker Radeloff will present an economic model to predict housing density around lakes based on zoning policies and other development constraints. They report that decreasing the minimum frontage zoning will increase lakefront housing density. Since bluegills are known to be adversely affected by increasing development, they predict that reducing frontage minimums would substantially compromise bluegill growth.
Jereme Gaeta, Stephen Carpenter, and colleagues have found that growth rates of most size classes of largemouth bass, a popular sport fish, are also negatively impacted by development. In 16 northern Wisconsin lakes, they found that larger fish grow more slowly in lakes surrounded by more extensive building than in less developed lakes. The effect is most pronounced on the largest bass, those over about 10 inches, which show a strong decline in growth rate with increasing numbers of neighboring homes.
