Abstract
Climatological factors such as temperature, wind, and precipitation have been reported to affect fish reproduction and recruitment in large lakes; however, little is known about these relationships in shallow, semi-permanent wetlands. We utilized age-O yellow perch (Perca flavescens) aquacultural harvest data to model climate effects on variability of juvenile yellow perch year class strength in semi-permanent wetlands. Overall, March through May precipitation, April air temperature, and a wetland parameter (i.e., intrinsic characteristics) provided the best-supported model. These results potentially indicate that spring weather patterns have an influence on yellow perch year class strength in semi-permanent wetlands.
