Invasive Species at the Aquarium

Big, public aquariums spend a lot of money to make fish look like
they’re at home in the wild, but lately some aquariums are showing fish
that are out of place. The GLRC’s Shawn Allee looks at one aquarium’s
effort to give them the spotlight, too:


The federal government’s spending millions to keep Asian Carp out of
the Great Lakes. Biologists worry Asian Carp could devastate the lakes’
ecosystem. Recently, though, several carp were brought within sight of
the Great Lakes, and biologists are happy about it.


Chicago’s Shedd Aquarium is on the shore of Lake Michigan. It’s
holding an exhibit of Asian Carp and other alien invasive species.


Curator Kurt Hettinger captured the aquarium’s carp during a trip on an
Illinois river.


“They’re literally jumping, sometimes over the bow of the boat,
sometimes smacking into the side of the boat. I just looked behind me
and was amazed to see all these fish jumping in the wake of the boat, and
to this day, I’m still stunned by this.”


And Hettinger’s more than just stunned. He’s worried.


Asian Carp are an invasive species, basically … pests that crowd out
native fish, and that river where he caught them hooks up to Lake
Michigan.


Again, Asian carp haven’t made it to the Great Lakes, but more than one
hundred and sixty other invasive species have arrived and are breeding
quickly.


One example’s the zebra mussel. At first, scientists worried about how
much money it could cost us. Zebra mussels multiply so fast they can
block pipes that carry cooling water to power plants. But now, we know
the zebra mussel’s disrupting the lakes’ natural food chain.


In other words, invasive species are a huge economic and ecological
nuisance. That’s why the Shedd Aquarium started the exhibit.


“The public I think has seen enough stories about the damages and the
spread and the harmfulness, but those stories are not very often coupled
with solutions.”


That’s ecologist David Lodge. He says the exhibit tries to show how
people spread these species around. Lodge points to one exhibit tank. It
looks like a typical backyard water garden. It’s decked out with a small
fishpond, water lilies, even a little fountain shaped like an angel. It looks
pretty innocent, but Lodge says plants and fish you buy for your own
water garden could be invasive species.


“All those plants and animals that are put outside, then have an
opportunity to spread. Now, it doesn’t happen very often, but with the
number of water gardens, it happens enough so that they are a serious
threat to the spread of species.”


Birds or even a quick flood could move seeds or minnows from your
garden to a nearby lake or river.


The Shedd Aquarium’s not alone in spotlighting invasive species.
Several aquariums and science museums are also getting on board. For example one in
Florida shows how invasive species have infested the Everglades.


Shedd curator George Parsons went far and wide for inspiration.


“I was in Japan last year when we were planning this, and I just
happened to stumble across one of their aquariums and they had an
invasive species exhibit, except that they were talking about large mouth
bass and blue gill. You know, something that is our natives. So, it was
kind of ironic to see that out there. It was kind of neat.”


Like us, the Japanese take invasive species seriously. Back in 1999 the
humble Midwestern Blue Gill created a national uproar. Turns out, they
had taken over ponds throughout the Emperor’s palace, and how did the
bluegill get to Japan?


Probably as a gift from a former Chicago mayor. Apparently, the mayor
thought blue gill might make nice sport fishing in Japan. It was an
innocent mistake, but it’s just the kind of mishap biologists want all of us
to avoid from now on.

Great Lakes Restoration Plan Released

In April 2004, President George Bush created a task force to develop a
comprehensive Great Lakes restoration plan. The group recently
released its recommendations, but members already disagree about the
future of their proposal. The Great Lakes Radio Consortium’s Shawn
Allee reports:


Efforts to improve the Great Lakes face a major hurdle. Local, state and
federal programs overlap and sometimes duplicate one another. That
wastes a lot of time and money. President Bush wanted to change this. So, he
created a task force called the Great Lakes Regional Collaboration. For the
first time, cities, states, federal agencies, and Indian tribes would agree to
specific goals and how to reach them. By most accounts they succeeded.


Here’s Chicago Mayor Richard M. Daley.


“I can’t overstate what a major step forward this is for the Great Lakes.
For the first time, we’re all the same page with a common vision.”


The parties agreed to eight major goals. Among other things, they want
to restore wetlands along Great Lakes shorelines, they want to clean up
heavy metals that pollute lakebeds, and they want to keep sewage away
from public beaches. The cost for all this would stand at billions of
dollars, and that price tag caused a major rift.


Bush administration officials agreed to spend 300 million additional
dollars per year. That’s just a fraction of what states and environmental
groups hoped for.


Derek Stack is with Great Lakes United, an advocacy group. He says
states want to participate, but sometimes they can’t.


“I think a lot of the states simply don’t have the dollars necessary to pull
it off.”


Tribes, cities and states are being careful with their criticism. They want
to keep the door open for the administration to change its mind.


“To be fair to the federal administration, the states are saying we don’t
have federal money, and the feds are pointing out that we don’t exactly
have state money either, but the states have committed themselves to the
plan. So, now that they know what they’ve committed themselves to, the
budget building can begin. It’s hard to build a budget if you don’t have a
plan.”


Some critics are more strident, though. Illinois Congressman Rahm
Emmanuel says the administration needs this clear message. Federal
leadership requires federal money.


“There’s either action or inaction. This is the ninth report in five years,
and I hope it’s the last report. Now, there’s nothing that can’t be cured when
it comes to the Great Lakes that resources can’t take care of.”


Great Lakes advocates and state governments will be watching the next
few months closely.


Cameron Davis directs the Alliance for the Great Lakes. He says he’s
reserving judgment until the President releases a budget proposal.


“That budget will be released the first week of February, and if it has 300
million dollars in new funding, then we’ll know that the administration’s
serious. If it doesn’t we need to ask Congress to step in.”


Some legislators say that deadline might be too soon to judge the
ultimate success of the restoration plan.


Illinois Congressman Mark Kirk says other federal cleanup efforts came
after several reports and years of waiting. Congressman Kirk says the
prospects for the restoration plan are good. The Great Lakes region has
the strength of eight states standing behind it.


“When you look at the success of the Chesapeake Bay, and then the success
of protecting the Everglades, you see, once you come together with a
common vision, what a unified part of state delegation or in the case of
Florida, what an entire state delegation can do.”


On the other hand, it might be hard to keep eight state governments
focused on a common purpose.


There’s another wrinkle in the restoration plan as well. Canada lies on the other
side of the Great Lakes, and any comprehensive plan will require its
cooperation as well.
