Sea Lamprey Management and Research
The commission agreed to treat Oneida Lake tributaries in 1988 provided
that it could do so with no increase in budget.
The commission recommended that a lock and dam on Wisconsin's Fox River
be sealed to prevent establishment of sea lampreys upriver, and funded
a study to alleviate the impact of the sealed lock on boating opportunities.
The commission provided funds for development and installation of a Smith-Root
electrical barrier on the Pere Marquette.
Dr. Stacia Sower (U of N.H.) received funds for sea lamprey endocrinology
research at Hammond Bay.
Dr. Joe Koonce (Case Western Reserve) received funds to complete a support
system for integrated management of sea lamprey.
Agents began spawning ground observations and nest surveys in the St. Marys
River in preparation for the implementation of a sterile-male-release technique.
Fishery Management, Environment, and Research
The commission provided funds for a Wisconsin DNR study on population and
distribution of the newly introduced ruffe.
The commission supported Council of Lake Committees and Great Lakes Fish
Disease Control Committee scoping of an introductions initiative, thereby
supporting development of a basinwide policy and a definition of information
Dr. Charles Krueger (Cornell U) received funds for assessment of predation
on lake trout eggs and fry.
The commission provided funds for Dr. Tom Edsall's (USFWS) mapping of lake
trout spawning grounds in Lakes Erie and Ontario.
Dr. Ruth Phillips (U of Wisconsin) received funds for research on lake
trout nuclear DNA.
The commission agreed to address the issue of ballast water introductions
and to fund a Wisconsin DNR study of ruffe.
The commission agreed to provide a forum on the progress and problems in
establishing a common consumption advisory.
The commission contributed to the review of the 1978 Canada-U.S. Great
Lakes Water Quality Agreement.

Committee Action, Resolutions, and Reports
The Council of Lake Committees recommended that the GLFC contract
with Tom Gorenflo (COTFMA) for archiving pre-1985 Great Lakes stocking
data. The council asked that the GLFC find an agency willing to host and
update the material.
The Lake Erie Committee requested funds from the GLFC to apply new
indices of abundance and modeling approaches to historical yellow perch
data in the University of Guelph mainframe computer. The committee agreed
to develop a model that would predict forage abundance, diversity, and
production under a wide range of predator (including man) densities.
The Lake Huron Committee approved plans for a 2-day workshop to
develop a definitive set of milestones for a sequence of clear indicators
of progress in lake trout rehabilitation. The committee pledged to work
with New York DEC to comment on the scope of the Habitat Advisory Board's
proposed artificial reef policy.
The Lake Michigan Committee requested that the GLFC send a letter
to the Governor of Wisconsin recommending that a lock on the Fox River
be closed and sealed to prevent the entry of sea lampreys. The committee
referred to the CLC a request that lake trout commercially harvested, transported,
or processed in Great Lakes jurisdictions be tagged.
The Lake Ontario Committee supported HAB's cautious approach in
seeking support data to develop a position statement on artificial reefs.
The need to determine the purpose for which a reef was proposed, the location,
materials, cost/benefit, and its impact on fish populations were items
the committee felt must be included in criteria in proposing or approving
the construction of artificial reefs. The committee noted that aquaculture
may hold great promise for productive utilization of Great Lakes resources,
but also posed potential threats related to the introduction of exotic
species and fish diseases.
The Lake Superior Committee asked the Lake Superior Technical Committee
to plan a 2-year lakewide program marking (finclip and coded wire tag,
if necessary) chinook salmon in order to determine rates of natural reproduction
and distribution of stocked and native chinooks. Committee members (with
the exception of Michigan DNR) supported the Great Lakes Indian Fish and
Wildlife Commission's proposal for a lake trout hatchery. Some questioned
whether additional hatchery facilities would be required by 1995 if current
progress in achieving lake trout and salmon natural reproduction continued.
Board of Technical Experts
Proposed research in four main areas: integrated management of sea lamprey
(IMSL), lake trout rehabilitation, fish community goals, and innovative
Habitat Advisory Board
Completed its draft Guidelines for Habitat Management and Planning.
Members emphasized that when Superfund and other funds were allocated for
clean water programs, fish and wildlife funding needs should be clearly
identified. Unless fish and wildlife needs are specifically included in
Great Lakes environmental programs, degradation and loss of habitat would
continue. Contaminants were not just seen as a drinking water problem,
but rather as an ecosystem problem.
Great Lakes Fish Disease Control Committee
Reported the continued presence of enteric redmouth disease and bacterial
kidney disease. Immunization methods and selective breeding were being
utilized to control furunculosis and infectious pancreatic necrosis. Severe
losses of lake trout in Michigan and Wisconsin state and federal facilities
appeared to be the result of a Chlamydia-like organism.
Supported a plan for the management and transfer of non-indigenous species
in the Great Lakes basin.
The commission conveyed support for Red Cliff Band construction of a lake
trout hatchery for rehabilitation purposes, emphasizing the need to raise
several genetic strains and to reach the production capacity necessary
to meet the needs of the lake trout management plans in the upper lakes.
The commission received the following funds from the United States and
Canada (in U.S. dollars):
