PARTNERSHIP WILL MEASURE EFFECTS OF AQUATIC NUISANCE SPECIES ON
GREAT LAKES FOOD WEB, FISHERIES
A group of Great Lakes
organizations have joined forces to measure the impact of aquatic
nuisance species on the Great Lakes food web and on sport and
The Great Lakes Fishery Trust, the Great Lakes Sea Grant Network, and
the Great Lakes Fishery Commission have formed a partnership on food
web disruption in order to address this critical issue more
effectively. Some aquatic nuisance species affect native sport and
commercial fish populations when they prey upon the same organisms for
food, disrupt spawning sites, and prey upon spawn and newly hatched
fry. This contributes to fish population declines.
The partnership will enable the groups to prioritize funding and
coordinate research. The coordinated approach will enhance the
effectiveness of individual research projects. For example,
information learned about the food web structure in one lake can be
used to predict future impacts in the other lakes. The partners also
anticipate that this approach will increase research
"This partnership is a critical step in our efforts to understand
how non native species are currently disrupting food webs and what
these food webs are likely to look like in the future," said
Bernie Hansen, chair of the Great Lakes Fishery Commission.
The partnership will focus on the
effects of four nonnative invertebrates: these include zebra
mussels (Dreissena polymorpha), quagga mussels (D.
bugensis), spiny water flea (Bythotrephes cederstroemi),
and the fishhook water flea (Cercopagis pengoi). These four
species have invaded the Great Lakes over the past 15 years and are
expected to have increasingly severe impacts.
The Great Lakes Fishery Trust was
created to compensate the citizens of the State of Michigan for the
lost use and enjoyment of fisheries resources of Lake Michigan
resulting from the operation of the Ludington Pumped Storage Plant.
Great Lakes Fishery Trustees represent the State of Michigan, Michigan
United Conservation Clubs, National Wildlife Federation, Grand
Traverse Band of Ottawa and Chippewa Indians and United States Fish
and Wildlife Service.
The Great Lakes Fishery Commission, created under the Convention on
Great Lakes Fisheries of 1955, was formed by the governments of Canada
and the U.S. to control the sea lamprey, coordinate fishery management
and conduct research.
The Great Lakes Sea Grant Network
is comprised of university-based programs in Illinois-Indiana,
Michigan, Minnesota, New York, Ohio, Pennsylvania, and Wisconsin.
Great Lakes Sea Grant Network programs conduct Great Lakes research,
education and outreach and are funded by the National Sea Grant
College Program of the National Oceanic and Atmospheric
Administration, an agency of the U.S. Department of Commerce.
