Bull Trout Restoration


Over the last two centuries, bull trout populations have declined across North America. The bull trout, Salvelinus confluentus, once thrived in the Columbia River Basin and coastal rivers of Washington and Oregon, extending north into British Columbia and Alberta.

Bull trout are members of the genus Salvelinus, which also includes Arctic char, brook trout, and lake trout. Like its relatives, male bull trout exhibit brilliant colors during the spawning season. Bull trout migrate during summer, traveling up to 150 miles from lakes and rivers upstream to their natal headwaters to spawn.

A variety of factors have been cited in the decline of bull trout. Habitat degradation and fragmentation, migratory fish passage obstacles, poor water quality, the effects of climate change, bounty fishing, and the introduction of non-native fish species.

Currently, American bull trout populations are scattered across portions of Oregon, Washington, Idaho, Montana, and Nevada. They populate several river systems including the Klamath,Columbia and Snake River Basins. In 1998, bull trout were listed as a threatened species under the Endangered Species Act.

In 2011, bull trout were re-introduced into the Clackamas River after a nearly 50-year absence. The reintroduction team included representatives from the U.S. Fish and Wildlife Service, Oregon Department of Fish and Wildlife, U.S.Geological Survey, and Mt. Hood National Forest. The project was one of several bull trout restoration programs that are ongoing in western river systems.

Lake Erie Walleye - Yellow Perch Management

Management of Lake Erie's walleye and yellow perch fisheries has undergone several important changes in recent years. The Lake Erie Percid Management Advisory Group (LEPMAG) was established by the Lake Erie Committee in 2010.

The group facilitates discussions among state and provincial management agencies on Lake Erie and stakeholders and provides input to the Lake Erie Committee concerning management of the region's walleye and yellow perch stocks.

LEPMAG participants include Lake Erie Committee members, biologists, recreational and commercial fishers, and personnel from the Quantitative Fisheries Center at Michigan State University.

Each year, the Lake Erie Committee recommends a total allowable catch for walleye and yellow perch. Total allowable catch represents the number or weight of fish that can be caught by sport and commercial fishers without putting the stocks and fisheries at risk. The individual agencies implement the recommended total allowable catch.

The Lake Erie Committee comprises fishery managers from Michigan, New York, Ohio, Ontario and Pennsylvania. The committee’s work is facilitated by the Great Lakes Fishery Commission, a Canadian and U.S. agency on the Great Lakes.
