Sea Lamprey Management and Research
The commission directed the refinement of an existing flow model in order
to better predict dispersion of lampricides in the St. Marys River for
the purpose of estimating the effectiveness of treatment options.
Agents increased larval distribution survey efforts on the St. Marys River.
Dr. Steve Bowen (Michigan Tech.) and Dr. Margaret Docker (DFO) received
funds to determine how environmental effects in streams limit the production
of sea lamprey transformers.
The commission approved Dr. Stacia Sower's (U of N.H.) program to investigate
the biological effects of lamprey gonadotropin-releasing hormones and analogs
on reproductive processes and behavior in adult male sea lampreys, and
to examine the possibilities of using these analogs for sterilizing lampreys.
Fishery Management, Environment, and Research
The commission agreed to fund an environmental objectives workshop and
the development of a white paper, as recommended by HAB.
In response to requests from the lake committees, the commission agreed
to represent fishery agency interests in protecting the Great Lakes from
exotic species invasion via ballast water. To do so, the commission agreed
to write letters to scientists, political and agency allies, and shippers
thanking them for their role in preventing the release of exotic organisms,
and to recommend the conversion to regulations of Canadian Great Lakes
Ballast Water Management Guidelines.
The commission provided HAB with copies of its proposed position statement
on contaminants for review.
The commission sent a letter to the Council of Great Lakes Governors supporting
the Council of Lake Committees' position on implementation of a draft protocol
for a uniform fish consumption advisory.

Committee Action, Resolutions, and Reports
The Council of Lake Committees supported the Lakes Erie and Superior
environmental objectives workshop and agreed to participate. Council members
expressed concern that there were no institutional arrangements for receiving
and accomplishing objectives, that fishery objectives were being developed
in isolation from other users, and that the engineering/biology gap must
be bridged. The council supported the HAB recommendation to the GLFC that
it encourage parties to re-define LaMPs to be a more comprehensive and
to develop a strategic planning framework which would provide a neutral
forum for the integration of fish and wildlife planning, coordination of
Remedial Action Plans, control of critical pollutants, and other components
of ecosystem management.
The Lake Erie Committee, with respect to a common U.S. contaminant
advisory, urged scientific review, urged research by EPA and Trust Fund
on risk assessment assumptions, urged reconciliation with FDA standards
and Canadian advisories, and urged delay until Health Canada research became
The Lake Huron Committee resolved that lake trout not be stocked
north of 45 until two years before effective sea lamprey control measures
are scheduled for the St. Marys River. The committee requested that the
commission develop a clear plan for sea lamprey control on the St. Marys
River with objectives, option evaluation plans, time frame, decision points,
and cost estimates.
The Lake Michigan Committee reaffirmed its Racine, WI decision to
stock Green Lake and Marquette strain lake trout in the southern refuge
in 1994. Fall fingerlings would be stocked in secondary areas. The Lake
Michigan Technical Committee continued its study and documentation of lake
trout which spawn at depths of 100'-150'.
The Lake Ontario Committee agreed to develop a tight protocol for
use of the Sustainability of Intensively Managed Populations in Lake Ecosystems
(SIMPLE) model in order to assure its integrity.
The Lake Superior Committee supported the proposed workshop on environmental
objectives. The committee authorized Binational Program incorporation into
its state of the lake report of LSC document of the same name.
Board of Technical Experts
Recommended the development of its biodiversity task during 1994, a year
of serious fiscal constraint, because the commission was reluctant to initiate
new research tasks during a year of budget shortfall. The board noted that
the biodiversity task may not be implemented until 1995.
Great Lakes Fish Disease Control Committee
Recommended that no lake trout egg collections from the upper lakes be
made until a screening test was available for epizootic epitheliotropic
disease virus. Despite promising news in 1991 about the development of
a screening test, equipment breakdowns and other problems delayed the test.
Completed its Protocol to Minimize the Risk of Introducing Emergency Disease
Agents with Importation of Salmonid Fishes from Enzootic Areas. The protocol
recommended advance consultation with other Great Lake agencies, stringent
disease monitoring at source, and a minimum six month quarantine in the
Great Lakes basin before stocking.
Habitat Advisory Board
Redrafted its Position Statement on Toxic Contaminants and recommended
that the commission endorse and publish the statement.
Recommended that the commission continue to review Stage I RAPs and agree
to review Stage II RAPs for the IJC.
The commission distributed copies of its video Great Lakes Invader: The
Sea Lamprey Battle Continues.
The commission received the following funds from the United States and
Canada (in U.S. dollars):
