"The purpose of this research is twofold: first, to provide baseline data on the use of the Southern Lake Michigan (SLM) sportfishery and, second, to further refine and test the concept of "recreational specialization.​" The report contains a generalized angler profile, including fishing knowledge, preferences, and sociodemographi​cs. It also presents a detailed look at the angler's management preferences and motivations. Included are estimates on the extent to which pollution affects their decision to fish in SLM or to eat their catch. A fishing specialization model is developed as a means for managers to better understand the differences among anglers in ways that may have significant implications for managing the social and biological aspects of sportfishing. Appendices contain additional information on a mailed survey as well as facsimiles of the cover letters, follow-up reminders, and questionnaires used"--National Sea Grant Library publication website.
