More info on Shiners/Spiney Water fleas

4 posts in this topic

Just heard a story on Channel 10 Duluth about the Spiney Water Fleas and they stated that licensed Bait dealers can trap shiners but must undergo training. Anybody confirm this?

The news release I saw confirms what you heard. Good news

for bait catchers and sellers. There will also be people

at boat landings to inspect and educated fishers about

disposing of bait and draining live and bait wells to try

and stop the spread.

Chores that need doing.

Hey, Lakeowoods what do you think of this?

LAKE OF THE WOODS: Spiny water flea means changes for bait dealers

By Brad Dokken, Herald Staff Writer

Published Sunday, March 18, 2007

Licensed bait dealers can continue trapping emerald shiners on Lake of the Woods and Rainy River, but private trappers will have to stop, now that spiny water fleas have been detected in the Rainy River basin.

But it won't be business as usual, officials say. Bait dealers will have to go through training to learn about preventing the spread of spiny water fleas or their eggs.

The Minnesota Department of Natural Resources on Monday designated Lake of the Woods and Rainy River as “infested waters” for spiny water fleas. The aquatic invasive species was documented in Rainy Lake last summer and eventually will work its way down the Rainy River into Lake of the Woods, if it hasn't already, officials say.

State law prohibits trapping bait from infested waters. The exception, in this case, will be trained bait dealers on Lake of the Woods and Rainy River.

Native to northern and eastern Europe, spiny water fleas are tiny invertebrates that measure about one-fourth to one-half inch in length. They interrupt the natural food chain by competing with zooplankton that young game fish rely on for food.

Spiny water fleas also collect on fishing lines and other equipment, making them a nuisance to anglers.

The invasive fleas first showed up in the Great Lakes in the 1980s in the ballast water of ships and since have spread to a handful of waters in Minnesota and along the Ontario border, most recently in the Rainy River basin.

According to Mike Larson, area fisheries supervisor for the DNR in Baudette, Minn., representatives from the agency met with the bait dealers last week to discuss the impact of spiny water fleas on shiner trapping efforts.

Larson said about 15 licensed bait dealers between Greenbush and International Falls, Minn., trap shiners on the Rainy River. Only those who go through the required training will receive permits to continue trapping, Larson said.

Larson says he's not sure when training for the dealers will begin, but it will be sometime before the fall shiner run, when trappers collect most of their minnows. He says DNR staffers want to learn more about measures to kill spiny water flea eggs from the Minnesota Sea Grant, a Duluth-based research group that has extensive experience with the species.

That information is crucial because spiny water flea eggs are highly resilient and even can pass through the digestive systems of fish and birds intact.

“We haven't thought that through yet,” Larson said. “We want to have the best information before we have the training.”

Meanwhile, Larson said, the ban means local anglers who trap their own shiners have to stop.

“They'll have to go through a dealer, which is very inconvenient and costly, but that's the way the law is right now,” Larson said.

Monday's designation of Lake of the Woods and Rainy River as infested waters also paves the way for stepped-up education efforts to teach anglers about preventing the spread of spiny water fleas. Larson says DNR staff will erect billboards along highways and hire inspection crews to be on hand at boat landings.

Boaters on infested waters must drain their livewells, Larson said; transporting water - even in bait buckets - is illegal.

It's not just anglers and boaters who have to change their habits, Larson said; there's also a learning curve for the DNR. All of the different DNR divisions that work on Lake of the Woods and Rainy River will have to learn how to disinfect boats and equipment so they don't inadvertently transport the fleas or their eggs to uninfested waters.

Larson said he soon will be writing a management plan to address those prevention measures.

“We don't want to be the culprit that moves them around,” Larson said. “We're going to have to do some training on ourselves.”

Yes thats right and I ran out of them way to early this winter, next winter I plan on having an endless supply if all goes right, I would have had enough this winter but it was busier than normal sold them real quick, I still have frozen emeralds which work just as good or better at times. We all got to like Curt said do the boat cleaning and livewell flushing on the boat landings BEFORE you leave any access on Lake Of The Woods.and any lake in Minnesota your supposed to do it also.

      Thanks for the ice report, Sculpin.  With the weather forecasted for the upcoming week, I'm sure I'll be up there next weekend, hopefully walking out from the northwest side.   van, yeah, I hear you.  I've been up to LOW a few times, and it is very fun to know there's the chance of catching a monster....but driving all that way for a bucket full of 12'' fish?  Not my cup of tea. I'll save the money and buy three dozen T-bones to make it through the winter. I'm sure people who know the lake better than I do have done better on the weekends I'm up there, but the reports at the resort we used were pretty similar.    I like the northwest side on ML because it's where we've been for almost 20 years, but it also has close access to sand, rocks, whatever weeds remain, mud flats, transitions, etc. The only thing we don't have up there is extensive gravel.

      I'm curious to see how this works out. Do you plan to keep the battery warm while not is use on the water?
