Recreational fisheries are valued at $190B globally and constitute the predominant way in which people use wild fish stocks in developed countries, with inland systems contributing the main fraction of recreational fisheries. Although inland recreati

Improved Models for Predicting Walleye Abundance and Setting Safe Harvest Quotas in Northern Wisconsin Lakes

Autor: Steven W. Hewett, Joseph M. Hennessy, Thomas A. Cichosz, Gretchen J. A. Hansen

Publikováno v: North American Journal of Fisheries Management. 35:1263-1277

In Wisconsin, the management of Walleyes Sander vitreus relies on a set of log-linear regressions to predict Walleye abundance and to set safe harvest. The regression models predict mean Walleye abundance from lake area, but they ignore variability a

Predicting walleye recruitment as a tool for prioritizing management actions

Autor: Stephen R. Carpenter, Jereme W. Gaeta, M. Jake Vander Zanden, Joseph M. Hennessy, Gretchen J. A. Hansen

Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 72:661-672

We classified walleye (Sander vitreus) recruitment with 81% accuracy (recruitment success and failure predicted cor- rectly in 84% and 78% of lake-years, respectively) using a random forest model. Models were constructed using 2779 surveys collected

The Relationship between Age-0 Walleye Density and Adult Year-Class Strength across Northern Wisconsin

Autor: Andrew H. Fayram, Jonathan F. Hansen, Joseph M. Hennessy

Publikováno v: North American Journal of Fisheries Management. 32:663-670

Walleyes Sander vitreus are an important cultural and economic resource in northern Wisconsin, both as a recreational fishery and a tribal subsistence fishery. Understanding the recruitment of age-0 walleyes to the adult population could be of great

Positive Effects of Agricultural Land Use Changes on Coldwater Fish Communities in Southwest Wisconsin Streams

Autor: James Baumann, Joseph M. Hennessy, David W. Marshall, Andrew H. Fayram, John C. Panuska

Publikováno v: North American Journal of Fisheries Management. 28:944-953

The Conservation Reserve Program (CRP) is a federal program that encourages the planting of cool- or warm-season grass cover on highly erodible croplands and along stream corridors. We sought to determine whether fish community structure in coldwater
