Environmental change in the Great Lakes Systems of the World:

Management of Lake Huron

Objectives for Management

The overall objective for Lake Huron is to:

  • over the next two decades restore an ecologically balanced fish community dominated by top predators and consisting largely of self-sustaining, indigenous, and naturalized species capable of sustaining an annual harvest of 8.9 million kg.

Specific objectives include:

  • Establish a diverse salmonine community that can sustain an annual harvest of 2.4 million kg with the lake trout (Salvelinus namaycush) as the dominant species and anadromous species also having a prominent place.
  • Reestablish and/or maintain the walleye (Stizostedion vitreum vitreum) as the dominant cool-water predator in its traditional area with populations capable of sustaining a harvest of 0.7 million kg.
  • Maintain the yellow perch (Perca flavescens) as the dominant nearshore omnivore and sustain a harvestable annual surplus of 0.5 million kg.
  • Maintain the northern pike (Esox lucius) as a prominent predator throughout its natural range.
  • Maintain the muskellunge (Esox masquinongy) in numbers and sizes that will safeguard and enhance the species status and appeal.
  • Sustain a harvestable annual surplus of 0.1 million kg of esocids. Maintain the channel catfish (Ictalurus punctatus) as a prominent predator throughout its natural habitat while sustaining a harvestable annual surplus of 0.2 million kg.
  • Maintain the present diversity of coregonines. Manage the lake whitefish (Coregonus clupeaformis) and ciscoes (Coregonus spp.) at levels capable of sustaining annual harvests of 3.8 million kg. Restore the lake herring (Coregonus artedi) to a significant level and protect, where possible, rare deepwater ciscoes (Coregonus reighardi).
  • Sustain the smallmouth bass (Micropterus dolomieu) and the largemouth bass (M. salmoides) and the remaining assemblage of sunfishes (Centrarchidae) at recreationally attractive levels in their natural range.
  • Increase abundance of the lake sturgeon (Acipenser fulvescens) so that the species is removed from its threatened status in United States waters. Maintain or rehabilitate sturgeon populations in Canadian waters. Maintain a diversity of prey species at population levels matched to primary production and predator demands.
  • Reduce sea lamprey (Petromyzon marinus) populations to allow achievement of other fish-community objectives.
  • Achieve a 75% reduction of the parasitic sea lamprey by the year 2000 and a 90% reduction by the year 2010.
  • Recognize and protect the array of other indigenous fish species because they contribute to the richness of the fish community. These fish-cyprinids, rare ciscoes, suckers (Catostomus spp.), burbot (Lota Iota), gars (Lepisosteidus spp.) and sculpins (Cottidae)-are important for three reasons. They have ecological significance; intrinsic value; and social, cultural, and economic worth.
  • Maintain and promote genetic diversity by conserving locally adapted strains.
  • Ensure that strains of fish being stocked are matched to the environments they will inhabit.
  • Protect and enhance fish habitat and rehabilitate degraded habitats. Achieve no net loss of the productive capacity of habitat supporting Lake Huron fish communities and restore damaged habitats.
  • Support the reduction or elimination of contaminants.
