You can download this sushi guide, print it out and carry it around with you if you
want, but Kate McLaughlin with the Blue Ocean Institute’s Seafood Program says
you could just look at it on your mobile device next time you go to a sushi bar.
“You can download a PDA formatted copy of the guide to your mobile device. Or
text the word ‘fish’ and then the name of the fish in question. Pretty much
immediately you get a response with the ranking.”
And it will tell you things like popular sushi such as bluefin tuna and farmed salmon
are on the “red” list, which means they’re either over-fished or farmed with
aquaculture methods that pollute the ocean.
You can get the guide at blueocean.org.

You might not be getting what you paid for in the seafood section of your
grocery store. The Great Lakes Radio Consortium’s Lester Graham reports a new
study has found some fish are being sold in the guise of others:
A new study finds cheaper fish are being sold as ‘red snapper.’ Amy Moran at
the University of North Carolina is a co-author of the study published in
Nature . She says DNA tests showed three-fourths of the ‘red snapper’
filets they tested from grocery stores were actually other species. Moran says
consumers are being deceived a couple of ways:
“The public perception of how common these species are is obviously influenced
by how common they appear to be on the marketplace. And if you go to the
grocery store and see Red Snapper everywhere and it’s $6.95 a pound, you can
rightly assume that it’s fairly common. But if what you’re getting is something
different, it’s going to lead to some public misapprehension of how common these
species are and that may at some level affect policy.”
Because less valuable fish are being reported as ‘red snapper’ catches,
fisheries managers are fooled into overestimating the population of the fish,
contributing to over-harvesting.

States in the Mississippi River Basin are protesting a decision by the state of Mississippi to
allow a foreign fish to be introduced to control a pest. The Great Lakes Radio Consortium’s Lester
Graham reports the other states are concerned the fish will escape into the wild and damage the
environment:
If you buy a package of catfish filets at the supermarket or order blackened catfish at your
favorite restaurant, chances are that fish was raised in a farm pond in Mississippi. The state of
Mississippi supplies almost three-fourths of the world’s commercial catfish. It’s a two-billion
dollar a year business, coming in only after cotton and timber as one of Mississippi’s largest
industries.
In recent years, Mississippi farmers have been struggling with a parasite that’s attacking the
catfish. Jimmy Avery is a researcher with the National Warmwater Aquaculture Center at Mississippi
State University. He says the parasite is causing quite a bit of damage.
“It’s either killing these fish outright or it’s stressing them to the point they no longer grow.”
Avery says the parasite makes its home in snails. To get rid of the snails, the Mississippi
Department of Agriculture and commerce has approved introducing an Asian fish called the black
carp. The black carp eats snails and mussels. But, other states are worried that the black carp
will escape the farm ponds and get into the wild. Avery says that’s not likely…
“The Mississippi Department of Agriculture and Commerce has decided that through the permit
process, we can minimize this. They’ll know where every black carp is located. They’ll know what
kinds of system they’ve been put in and it felt like that those regulations that had been put in
place are strong enough to prevent that.”
But the State of Missisippi’s assurances don’t convince others. Roger Klosek is the Director of
Conservation at the Shedd Aquarium in Chicago. He studies native mussels.
“If black carp are used to deal with the snail problem, eventually they’ll escape into the main
waterways, and start reproducing. And once they do that, they’ll start feeding on the native
mussel fauna which is one of the last remaining native mussel faunas in the United States and
literally wipe it out.”
Klosek says native mussel populations have already been hurt by another exotic species, the zebra
mussel. He believes the black carp would be the last straw for American freshwater mussels.
“So, somebody’s going to lose and it’s probably better – I know the catfish farmers will hate me
for saying this, but – it’s probably better that they lose a little economically rather than
reduce some of the native fauna to an irretrievable state.”
Some states’ officials agree with Klosek. Bill Bertrand works with the Illinois Department of
Natural Resources fisheries office. He says there’s a history of Asian carp getting loose. The
silver carp, the bighead carp, and the grass carp have already escaped from farm ponds, mostly
from Arkansas where there are few regulations.
“There’s a history of these exotics, imports, escaping into the river system, spreading throughout
the entire river basin system and causing impacts on all the other states in the system. And
Mississippi appears to tend to ignore that fact and go ahead their own merry way, saying ‘Well
we’re doing this because we want to do it and it’s beneficial to us.'”
Bertrand says governors of some of the states along the Mississippi River have sent letters to the
Governor of the State of Mississippi, asking him to stop the use of black carp. Several of the
states intend to ask the U.S. Fish and Wildlife Service to ban the importation of the fish. The
federal agency has not yet received that request… but even if the Fish and Wildlife service
found a ban was appropriate, it would take several months to go through the process. Even then, a
ban would not apply to black carp already in the U.S.
Mike Oetker is a fisheries biologist with the Fish and Wildlife service. He says the agency is
trying to play the role of mediator.
“Right now the U.S. Fish and Wildlife Service is trying to work with states and the industry to
try to prevent the problem of the possible release or accidental release of black carp into the
environment. There are several alternatives to black carp where we can use native fish such as the
red ear sunfish or freshwater drum or even big mouth buffalo to do the same type of biological
control that the black carp are doing. And that would give of the ability to kind of circumvent
this problem.”
The catfish farmers in the State of Mississippi say the native fish don’t eat the snails as
quickly as the black carp. The Mississippi Department of Agriculture and Commerce says it will ask
farmers to use chemical treatments first and where native fish will work, they’ll try to use them.
but in the end, the Mississippi agency says it will allow catfish farmers to use black carp when
it appears other methods don’t work.

An exotic species is making its way toward Lake
Michigan… from Lake Superior. The Great Lakes Radio Consortium’s
Mike Simonson reports that the Eurasian Ruffe (ROUGH) fish is
multiplying at a rate wildlife specialists can’t control, threatening to
spread to other Great Lakes:
As trout fishing season opens up throughout the country this month
(April), many fisherman will be lining the banks of streams, lakes
and ponds. One thing that may startle these anglers is the large
amount of dead fish washing up on the shore. But as the Great Lakes
Radio Consortium’s Tom Scheck reports, conservation officials say
pollution and chemical spills may not be to blame:
