Some researchers say global warming will impact fish habitat in the
Great Lakes. Chuck Quirmbach reports:


Some scientists have projected that more global warming will mean less
rain and snow falling into the Great Lakes and the continuation
of low water levels.


Researcher Brian Shuter is with the Ontario Ministry of Natural
Resources. He says if the projection comes true, there will be
more stress on the millions of Great Lakes fish:


“I mean the space for fish to live in is just gonna shrink and the less
space there is, the less fish there will be.”


Shuter also anticipates higher summertime water temperatures and less
ice cover in the lakes. That’s a change that could lead to more warm
water fish like bass and fewer of the cold water fish like salmon
and trout that people like to eat.


Shuter says the change could also promote the growth of invasive
species that favor warmer water temperatures. So, he encourages tighter
controls on invasives and more water conservation programs.

New National Board Aims to Protect Native Fish

A new, national effort to protect aquatic species and habitats could bring needed cooperation between state and federal agencies. Individual states aren’t able to deal with the problems themselves, but say the newly-formed coalition of partners might help. The GLRC’s Kaomi Goetz reports:

A new, national effort to protect aquatic species and habitats could bring
needed cooperation between state and federal agencies. Individual states
aren’t able to deal with the problems themselves, but say the newly-
formed coalition of partners might help. The GLRC’s Kaomi Goetz
reports:


The goal of the National Fish Habitat Action Plan is to clean up the
nation’s rivers, lakes and coastal areas. It also seeks to protect the more
than 800 different kinds of native fish from extinction. The plan is based
on an earlier successful model focused on the nation’s waterfowl.


Federal agencies, industry, tribal and non-profits groups have signed on.
So have several state Department of Natural Resources. Gary Whelan is
with the Michigan DNR, one of the agencies that’s signed on.


“When you’re trying to deal with things like water quantity in a system, and you
have a 100 dam owners you’re trying to communicate with, a couple
(state) agencies can’t possibly do that, nor do we have the financial
resources so you really need a broad-based coalition of people.”


Whelan says the initiative will mean a lot more money for states to
address water quality problems and fish habitat.


Organizers are creating a national board to coordinate all the efforts.

Reward for Tagged Fish

Great Lakes scientists are using new technology to track certain kinds of fish. The Great Lakes Radio Consortium’s Jonathan Ahl reports:

Great Lakes scientists are using new technology to track certain kinds of fish. The Great Lakes Radio Consortium’s Jonathan Ahl reports:


Researchers on lakes Huron and Superior are using a new computerized tagging system to track fish including trout and sturgeon. The new tag measures the water depth and temperature of the areas fish prefer to be. Henry Quinlin is a biologist with the U.S. Fish and Wildlife Service in Ashland, Wisconsin:


“Upon learning the habitat preferences, habitat could be enhanced or created to benefit lake sturgeon or the other species that are being studied.”


Quinlin hopes the data can be used to design better habitat protection and restoration projects. He also says the program’s success is dependent on sport fisherman returning the tagged fish. That’s why his office is paying one hundred dollars a piece for fish with the special tags. For the Great Lakes Radio Consortium, I’m Jonathan Ahl.

Artificial Reefs: A Help or a Hindrance?

Artificial reefs are being built in the Great Lakes to attract fish.
Sport fishing groups like them because the reefs make it easier to catch
fish. However…the Great Lakes Radio Consortium’s Lester Graham reports
some conservationists are concerned the artificial reefs could destroy
natural habitat:
