Abstract

Abstract In Escanaba Lake, Wisconsin during 1958–1980, significant negative correlations were found between the fall density of age-0 walleyes Stizostedion vitreum and both the standard deviation and coefficient of variation of the May water temperatures. Age-0 walleye density in fall over the 23-year period was not influenced by several other temperature relationships or by wind speed and direction, water level, adult density, or density of previous year classes. The first-year growth of walleyes in Escanaba Lake was positively related to the June and combined May-June water temperatures but was not significantly related to temperatures during May or the July-August and May-August periods.
