The history of brown trout Salmo trutta in North America extends back to 1884, when brown trout fry were successfully introduced into a tributary of Michigan's Pere Marquette River. The introduction of brown trout, brook trout Salvelinus fontinalis, and rainbow trout Oncorhynchus mykiss, along with unregulated logging and over-fishing, contributed to the extinction of Arctic grayling, which were the native and primary resident salmonid species in many of Michigan's coldwater streams. Today, stream-resident populations of brown trout and brook trout occur in 31,000 km of 1,500+ Michigan streams. In contrast with trout streams in mountainous areas, Michigan's trout streams are cooled, and their flows stabilized, by large inputs of groundwater associated with deep deposits of coarse-textured glacial drifts. Michigan has a long history of stream trout research. This overview highlights work on topics including hatchery trout stocking and strain evaluations, hooking mortality of trout, predation on trout, effects of sport fishing regulations, population and recruitment dynamics, temperature effects on growth, and factors influencing spatial patterns in trout abundance. Brown trout populations in Michigan are largely self-sustaining, with long-term population dynamics being driven by effects of flow conditions on reproductive success. Abundance, growth, and survival of brown trout in streams are also influenced by factors such as water temperature, nutrient, and instream habitat conditions, as well as intra- and inter-specific trout densities. Larger brown trout in Michigan streams are piscivorous, and often prey on and out-compete stream-resident brook trout. Managing Michigan's trout streams is a daunting task, especially considering that Michigan fisheries biologists are also responsible for 11,000 inland lakes and Michigan's portion (43%) of the Great Lakes. Partnerships are a key to success. Stream trout populations are assessed via surveys at long-term index stations (for trends), randomly selected locations (for a general inventory), and other locations of management interest. Brown trout are managed as recreational fisheries for the public. Minimum size limits, creel limits, fishing and harvest closures, and gear or fishing method restrictions serve as principle tools. Five combinations of these tools (i.e., regulation types) are used to manage stream trout populations. Protection, restoration, and maintenance of stream habitats are critical, given the immense capacity of Michigan streams to support self-sustaining trout populations and provide recreational benefits. These tasks are accomplished through collaboration between Michigan Department of Natural Resources (MDNR), the Michigan Department of Environmental Quality, several federal regulatory agencies, and concerned anglers, citizens, and partners throughout the state. Habitat issues highlighted include riparian habitat changes, chemical discharges, sedimentation, instream woody habitat, dams, fish passage, and water withdrawal. While over 90% of Michigan trout streams support self-sustaining populations, additional trout fishing opportunities are provided by stocking brown trout into waters that provide suitable habitat for year-to-year survival of stocked fish, but provide limited or no natural reproduction of trout. Stocked trout are produced by MDNR Fisheries Division hatcheries that use state-of-the art technology to efficiently produce high-quality, relatively disease-free trout with high genetic integrity. A mean of 729,000 brown trout (typically age-1 fish) have been stocked into Michigan streams annually since 1979.
