Abstract

Evergreen Reservoir was surveyed by the Region Two Warmwater Team June 6 â€" 15, 2005. Approximately 98 percent of fish sampled were warmwater gamefish. In addition, common carp (Cyprinis carpio) were also sampled. Bluegill (Lepomis macrochirus) were most abundant followed by largemouth bass (Micropterus salmoides), yellow perch (Perca flavescens), and black crappie (Pomoxis nigromaculatus). Black crappie, pumpkinseed sunfish (Lepomis gibbosus), largemouth bass, and smallmouth bass (M. dolomieui) exhibited high growth for all age classes, while yellow perch and bluegill growth varied among age classes. Relative weights were at or above the national average for largemouth bass, bluegill, pumpkinseed sunfish, and black crappie; however, relative weights were below average for walleye (Sander vitreus) and tiger muskie (Esox lucius Ã�" E. masquinongy). Relative weights declined with increasing length for yellow perch and smallmouth bass. Yellow perch, walleye, and carp declined in abundance in our samples from 2000 to 2005. Declines in abundance may be due to predation or lack of forage for walleye and perch. Declines in carp are likely the result of sampling bias. Abundance of tiger muskie collected was similar to that collected in 2000.
