Sea Lamprey Management and Research
The commission established a St. Marys River Task Force to provide a technical
assessment of sea lamprey infestation in the St. Marys River.
The commission approved funding for a sea lamprey barrier on Michigan's
Pere Marquette River, pending development of a suitable design.
The commission provided funds to modify the barrier on Michigan's East
Branch, Au Gres River tributary.
The development of a request for proposal for a study on identification
of trace elements in lamprey statoliths was approved. The purpose of this
study was to allow identification of streams of origin.
American Biogenics Laboratories received a contract from the commission
to conduct toxicity tests necessary for establishment of a tolerance for
TFM in meat, fish, milk, and potable water.
In cooperation with the University of Wisconsin, the commission funded
USFWS Region 3's development of a prototype electrofisher for lampreys.
The commission purchased a test batch of a new bottom formulation of TFM-clay-salt
for field testing by Hammond Bay.
Fishery Management, Environment, and Research
The commission funded the Lake Erie Committee in the development of a walleye
The Habitat Advisory Board was directed to identify priorities from the
resource point of view for Superfund, remedial action plans, and similar
cleanup programs, and to develop a contaminant policy and action plan.
Dr. Warren Flint (SUNY) received funds for a report on the state of the
Lake Ontario ecosystem.
Dr. Joe Koonce (Case Western Reserve) received funds to model Lake Ontario
sea lamprey/lake trout interactions.
Dr. Nancy Holm (Illinois State Geological Survey) received funds to develop
an inventory of lake trout research.
The commission provided Dr. Dan Talhelm (MSU) with funds to demonstrate
usefulness of socioeconomic studies in Lake Michigan fisheries management.
The commission approved for further development proposals for assessment
of degraded lake trout spawning shoals, for assessment of predation on
lake trout eggs and fry, for identification of lake trout stocks using
genomic DNA markers, for mapping lake trout spawning shoals, and for study
of attitudes and behavior of fishery clients.

Action, Resolutions, and Reports
The Council of Lake Committees urged each Lake Trout Technical Committee
to document requirements for coded-wire-tags and for offshore stocking
as specified in the plans and individual agencies' independent requirements
for tagging and offshore stocking. The Lakes Superior and Huron technical
committees were encouraged to incorporate performance indicators into their
lake trout rehabilitation plans.
The Lake Erie Committee agreed that it was important to develop
objectives for Lake Erie fish community structure, which would fit under
the SGLFMP goal statement. The committee approved and recommended that
the commission fund the Walleye Task Group's development of a centralized
database, as outlined in Gary Isbel's (Ohio DNR) proposal.
The Lake Huron Committee invited the Lake Trout Technical Committee
to begin addressing questions of forage and species interactions. The committee
requested a meeting with the commission to scope information needs for
determining the magnitude of the St. Marys River sea lamprey problems,
identifying the nature of management and control actions that were warranted,
and, if necessary, making a case for additional resources to conduct any
management or control actions.
The Lake Michigan Committee expressed concern about reduced growth
rates of chinook salmon and declining alewife stocks. The concern was reflected
in 10% cutbacks in salmon stocking by Michigan and Wisconsin and a hold-the-line
position by Indiana.
The Lake Ontario Committee agreed to draft a letter to agencies
regarding the importance of funding for collection and analysis in the
1987 fish tumor survey. Clif Schneider (NYDEC) was asked to collaborate
with Joe Koonce (Case Western Reserve) to develop models for Lake Ontario
which would quantify lamprey populations and lamprey-induced mortality.
The Lake Superior Committee established a Habitat Subcommittee to
develop a Lake Superior habitat plan, to facilitate incorporation of fishery
input into IJC remedial programs, and to ensure fishery agency participation
in review of the 1978 Water Quality Agreement. The committee adopted the
Lake Trout Technical Committee's lake trout rehabilitation plan and further
recommended that "special rehabilitation study areas" be found for areas
like the Huron Islands.
Board of Technical Experts
Established lake trout research as a task area with U.S. and Canadian co-chairs
charged with focusing research on perceived impediments to lake trout restoration
in the Great Lakes.
Great Lakes Fish Disease Control Committee
Reported that enteric redmouth disease (ERM) and epizootic epitheliocystis
disease (later identified as EED) were recurring problems, and that maintaining
the voluntary ban on imports from infectious hermatopoietic necrosis (IHNV)
enzootic areas remained difficult. The committee decided to pursue a fish
health database as a tool for use by both fish health and fish management
biologists. The committee noted that EED had been associated with significant
losses of lake troutin Michigan.
Habitat Advisory Board
Reported improved coordination with agencies and Great Lakes organizations.
The Habitat Planning and Management Task Force completed its guidelines
for fish habitat planning and management in the Great Lakes. The board
noted that record high waters were causing great public and governmental
The commission contracted with Meyer Resources for study of public perceptions
of sea lamprey control in the Great Lakes.
The commission sent a letter to IJC Commissioners on the need for fishery
agency participation in addressing areas of concern in remedial action

Canada (in U.S. dollars):
