Pacific salmon were introduced to the Great Lakes in the 1960s and now support major recreational fishery. Population declines resulting from invasive species have prompted agencies to consider diversifying sport fisheries through stocking. Atlantic

Atlantic salmon (Salmo salar) are native to Lake Ontario; but their populations severely declined by the late 1800s due to human influences. During the early to mid-1900s, Atlantic salmon were stocked throughout the Great Lakes in effort to reestabli

The first putative hybrid between pink salmon ( Oncorhynchus gorbuscha ) and Chinook salmon ( O . tshawytscha ) in the Laurentian Great Lakes was reported in 1992. Since that time, many St. Marys River anglers have reported catching hybrid ‘pinook

The St. Marys River, the sole outflow of Lake Superior, was historically inhabited by lake sturgeon ( Acipenser fulvescens ); until recently it was unclear whether a population was still present in the river. From 2000 to 2007, the population status

Historically, the St. Marys River (SMR), Michigan, provided suitable habitat for lake sturgeon ( Acipenser fulvescens ) but their population declined dramatically during the past century due to overharvest and habitat alteration. Since 2000, the Lake

Early mortality syndrome (EMS) is the term used to describe the mortality of juvenile salmonids due to thiamine deficiency within the Great Lakes basin. EMS appears to be related to the presence of thiaminase found in prey fish such as alewives Alosa

Population attributes and migratory dynamics of spawning pink salmon Oncorhynchus gorbuscha were examined in U.S. waters of the St. Marys River from 1998 through 2002. Spawning migrations were monitored twice each week from late August through early

Life-history characteristics, size structure, and relative composition of hatchery-reared and wild-produced steelhead Oncorhynchus mykiss in the Carp River, Michigan, were examined to determine if population attributes were similar between origins. Q

The fingerling hatchery performance attributes of brook trout Salvelinus fontinalis of Lake Nipigon origin were compared with those of domesticated (Assinica) and nondomesticated (Iron River) strains of this species in a 150-d laboratory experiment.

Atlantic salmon, (Salmo salar), were reared from eyed eggs at the Lake Superior State University Aquatic Laboratory and released as yearlings in 1987 and 1988 into the St. Marys River to establish a sport fishery. To study movement, estimate harvest,
