Sea Lamprey Management and Research
The commission directed agents to start treatment of Lake Erie in 1987
on the condition that treatment elsewhere not be diminished.
The commission provided funds for reconstruction of a barrier dam with
fish ladder for Wisconsin's Brule River.
Dr. Stacia Sower (U of N.H.) was granted funds to study the use of hormones
and their analogues to control reproduction and metamorphosis in sea lampreys.
Dr. Bill Beamish (U of Guelph) received research contracts to study techniques
for aging sea lampreys and for validating age determination by statoliths.
The commission funded re-examination of previously collected data for establishing
EPA tolerance levels for TFM.
Fishery Management, Environment and Research
The commission wrote to the U.S. Sec. of State and Canadian Sec. of State
for External Affairs regarding pollution on the Niagara and St. Clair Rivers,
and the implications for sport and commercial fisheries in Lakes Ontario
and St. Clair.
The commission urged agency support of the fish disease policy and model
program, supported the ban on importation of salmonid eggs or fish from
areas such as the West Coast where infectious hermatopoietic necrosis virus
(IHNV) is endemic, and supported educational initiatives on the fish disease
control program and its objectives.
The commission commended agencies for developing a uniform health advisory
for Lake Michigan fish and urged cleanup efforts and expansion of the uniform
The commission contracted with Dr. Jim Kitchell (U of WI) for studies on
food webs in Great Lakes fish communities.
The commission provided Dr. Jim Seelye (USFWS) with funds for equipment
and costs incurred in rearing and marking lake trout over a 3-year period
for of a joint study of lake trout habitat and hatchery effects, as called
for in the Conference on Lake Trout Research.
Dr. Rosalyn Stevenson (U of Guelph) received funds to study culture and
diagnostics of bacterial kidney disease.

Committee Action, Resolutions, and Reports
The Council of Lake Committees endorsed the task force review of
lake trout technical plans and noted that additional work on evaluating
goals and objectives (expectations and milestones) and criteria for establishing
stocking recommendations would be very useful.
The Lake Erie Committee expressed its gratitude to the U.S. Fish
and Wildlife Service for its commitment to assemble the Scientific Protocol
Committee's early work on walleye for publication in the commission's technical
The Lake Huron Committee agreed to write to the Ontario Ministry
of Natural Resources (OMNR) concerning the fate of the scarce shortnose
cisco. The letter would ask OMNR to look for isolated populations which
could be protected. It was hoped that a shortnose cisco population could
be located on the proposed mid-lake refuge.
The Lake Michigan Committee suggested that its technical committee
address fish community goals and predator capacity of the lake (e.g. salmon
units) in order that it may recommend to the committee on such matters
as stocking allotments, appropriate relative abundance of alewife in Lake
Michigan, and deliver a picture of fish community structure and trends.
The Lake Ontario Committee recommended to the CLC that it develop
a standardized form to use in which annual lake trout mortalities could
be attributed--with the best information available--to various sources
such as commercial, sport, illegal fisheries, sea lamprey, etc.
The Lake Superior Committee charged its technical committee to work
with Dr. Joe Koonce (Case Western Reserve) in developing his method and
in working out estimates of fish mortality due to sea lamprey attack, sea
lamprey abundance, etc. The states, the tribes, and the province agreed
to provide information to the extent possible.
Board of Technical Experts
Noting the need to participate in meetings dealing with development of
fish community goals, the board agreed to have members attend the IJC-sponsored
food web workshop.
Great Lakes Fish Disease Control Committee
Reported that despite recurrent problems and new outbreaks of various fish
diseases, reaction of agencies to control disease spread were effective
and no serious threats to the salmonid resources in the Great Lakes basin
Asked the commission to endorse voluntary restraints by member agencies
on importing salmonids from areas where infectious hermatopoietic necrosis
virus (IHNV) was endemic.
Habitat Advisory Board
Noted a general consensus by each lake committee that a focus on habitat
issues was necessary, and that habitat plans should be essential segments
of Great Lakes fisheries management plans and programs.
The commission provided statements in support of lake trout rehabilitation
at Wisconsin DNR hearings on fishing restrictions.
BOTE and HAB members received from the commission copies of the non-governmental
review of the 1978 Water Quality Agreement, and were asked, after consultation
with lake committees, to report to the commission about how the 1978 Water
Quality Agreement might be improved.
The commission received the following funds from the United States and
Canada (in U.S. dollars):
