Committee Action, Resolutions, and Reports
The Council of Lake Committees asked the Law Enforcement Committee
to analyze Great Lakes fishery regulations and to develop a model paper
legitimate fish sales. Lake committees were encouraged to develop draft
outlines for biennial state of the lake reports. The council requested
that the GLFC write to contracting parties regarding the need to address
the problems of live fish and other organisms being introduced in the Great
Lakes via ballast water.
The Lake Erie Committee requested that the commission provide funds
for a 10-year walleye tagging study. The committee encouraged the development
of an introductions policy for consideration by the Committee of the Whole.
The Lake Huron Committee approved the tabular information on historical
and desired harvests, etc, for presentation as a fish community objectives
working document. The committee noted Lake Huron had the highest abundance
of sea lampreys of all the Great Lakes and that gains could be reversed
if control was not maintained.
The Lake Michigan Committee agreed to seek agency feedback on commitment
and capability for a Michigan proposed lakewide tagging study of chinook
salmon natural reproduction and movement in Lake Michigan. The committee
approved plans to update the Lake Michigan lake trout rehabilitation plan.
The Lake Ontario Committee noted that budget cuts could jeopardize
the progress made in sea lamprey control and could preclude the attainment
of lake trout rehabilitation. The committee expressed concern over agency
interest in advising the public regarding the consumption of angler-caught
fish and added that such advisories, though important, must consistently
be oriented towards the primary purpose of enabling the recreational resource
user to make informed personal decisions.
The Lake Superior Committee urged the CLC to recommend emergency
action by the commission to prevent further introductions of the ruffe
and other exotics. The committee urged the GLFC secretariat to contact
European scientists for additional information on the biology of the ruffe.
Board of Technical Experts
Agreed to conduct a workshop in Wisconsin to explore system stability.
Agreed to focus attention on climate warming effects, stability of artificial
systems, and introductions.
Expressed its support for improved gear to assess ammocetes in large systems
and expressed concern about the environmental impacts of using large dredges
to survey ammocetes.
Great Lakes Fish Disease Control Committee
Reported that enteric redmouth (ERM) and bacterial kidney disease (BKD)
continued to be of concern. Efforts continued to control infectious pancreatic
necrosis (IPN) using selective breeding, and immunization methods were
being used to control ERM and furunculosis with mixed results.
Controlling sea lampreys with disease organisms was rejected.
Habitat Advisory Board
Continued to emphasize that fish (and wildlife) habitat needs to be an
integral component of all Great Lakes water level management policies,
and flow formulas. The board recommended that natural resource agency fishery
representatives be included as full members on water level boards, committees,
and other groups that help determine Great Lakes water level management.
The commission contributed funding for a PBS video on the decline and revival
of Great Lakes fisheries.
The commission wrote the Minister of External Affairs Canada and the U.S.
Secretary of State requesting measures to prevent the introduction of exotic
organisms into the Great Lakes via ballast water of ocean-going ships.
The commission received the following funds from the United States and
Canada (in U.S. dollars):
