Marquette Fisheries Research Station (MFRS) was established in 1952 and is housed in the Marquette State Fish Hatchery. Marquette's Great Lakes station merged with the Marquette Fisheries Research Station in 1983 to form a single entity. Research station work includes studies on fish species, communities, and ecologies in Upper Peninsula rivers, streams, inland lakes, and the Great Lakes.

A sampling of some of the past work conducted by station personnel includes studies on:

Inland Trout and Salmon

  • Rainbow trout-coho salmon population dynamics in Lake Superior tributaries
  • Evaluation of two-year cycles of abundance of age-0 rainbow trout in Lake Superior tributaries
  • Evaluation of hatchery-reared brook trout stocked in Upper Peninsula streams
  • Mark retention, survival, and growth of jaw-tagged and fin-clipped rainbow trout

Great Lakes Trout and Salmon

  • Juvenile lake trout morphological characteristics to assist differentiating between three forms (lean, humper, and siscowet) of lake trout
  • Assessment of early survival of young lake trout in lakes Michigan and Superior
  • Evaluation of the effects of DDT and PCB's on survival of lake trout eggs and fry in a Lake Michigan hatchery
  • Comparative recovery to the creel, movement and growth of rainbow trout stocked in the Great Lakes
  • Documentation of distribution, abundance, size, age, and fecundity of pink salmon in the Great Lakes
  • Dynamics of lake trout reproduction on two man-made spawning reefs in Lake Superior
  • Evaluation of planting eyed eggs as a means of restoring lake trout stocks in the Great Lakes
  • A cooperative evaluation of lake trout spawning habitat in the Great Lakes using in situ bioassay procedures
  • Evaluation of juvenile salmonid plants in Michigan waters of Lake Superior
  • Determining origin and population dynamics of Chinook salmon in Lake Superior
  • Migration, food habits, and predation on yearling coho salmon in a Lake Michigan tributary and bay
  • Fecundity of coho salmon in the Great Lakes compared with ocean salmon
  • Age, growth, and downstream migration of juvenile rainbow trout in a Lake Michigan tributary
  • Straying and reproduction of coho salmon planted in a Lake Superior tributary
  • Comparing population dynamics of Isle Royale and inshore lake trout stocks
  • Long-term assessment of inshore lake trout stocks in Lake Superior
  • Determining the number of non-target anadromous salmonids and lean lake trout captured and killed in an exploratory commercial gill-net fishery for siscowet lake trout, to determine if siscowets are preying on salmon and other trout, and to determine relative abundance and harvestable surplus of siscowet lake trout

Coolwater Species / Coregonids / Lamprey

  • Quantifying the utilization of alewives by inshore piscivorous fishes in Lake Michigan
  • Population dynamics of contemporary yellow perch and walleye stocks in Michigan waters of Green Bay
  • Assessment of age, growth, and mortality of chub stocks on fishing grounds surrounding the Keweenaw Peninsula
  • Determining harvestable surplus of lake whitefish and to specify the rates of non-target fish catch and mortality
  • Surveys to determine if larval sea lamprey inhabit lentic waters in Lake Superior, Lake Michigan, and Lake Huron drainages
  • Examining cadmium sulfide and mercuric sulfide for marking sea lamprey larvae
