DNR Stocking reports

[fishnowworknever]

So I am looking at the stocking reports, one of the lakes says:

CAP - 196 fingerlings weighing 4.8 lbs.

What does CAP stand for?

What lake were you looking at?

[fishnowworknever]

Lake Susan, Carver county.

I called the DNR, they stocked it with carp, in which they are tracking them to see where they end up.

Riley, Ann, Susan, Rice marsh are all connected, if any of you remember last year the big carp cleanup they had in Susan, well Riley has just as many carp if not more and they want to monitor these fish to see if/when they are entering these other lakes.

Interesting..

thats very interesting stuff right thur! i've never heard of the mn dnr STOCKING CARP! have they ever done this before? seems like kind of backwards thinking, but i guess i can understand their logic... that little chain of lakes already has so many carp in them, its beyond the point of no return. i hope i hear more about what they end up finding

Actually carp were first introduced to Minnesota by stocking efforts. It was believed that carp would be as popular, if not more popular with American anglers than they were in Europe. As it turns out, the carp are not the blessing they were once thought to be.

haha thats funny! i didn't know that either! i guess you learn something new everyday!

After the initial carp removal, the water clarity on Susan cleared so much that the algae bloom in late summer was so bad that it killed off much of the aquatic plants. They are now introducing plants back into the lake, along with the carp, just at a fraction of what they pulled out.

The idea is to track movement of carp and find larger schools. It's part of a larger biomanipulation study focused on carp removal:

Fish surgery: Carp research expands to Lake Ann

By Forrest Adams, Eden Prairie News

September 24, 2009

Prezemek Bajer is a doctor of philosophy (PhD.), but last Thursday afternoon, along the eastern shoreline of Lake Ann, he was a doctor of carp (Carp MD?).

Five common carp huddled under lily pads in a large live well aboard as Bajer snapped on a pair of surgical gloves. His partner in research, Chris Chizinski, prepared a Tupperware tub of fish anesthetic nearby.

Bajer reached into the tank and whisked out a 30-inch carp, placing it quickly and gently into the fish anesthetic before the fish even had a chance to flip or flop. Chizinski closed the covers, and for the next few minutes it grew numb.

Mike Casanova, from the Riley-Purgatory Bluff Creek Watershed District, stood nearby the bow of the boat watching.

“Lake Lucy and Lake Ann are at the top of the watershed,” Casanova said. “We want to clean up the complete watershed from here down. If we were to clean up Susan and Rice Marsh and Riley, but the carp were able to migrate back up to Ann or Lucy, they would be able to reproduce and come back down again.”

“Is it ready?” Bajer asked.

“Looks like it,” responded Chizinski.

He reached in, scooped out the motionless carp and laid it belly-up on a large piece of Styrofoam as Bajer prepared his gauze pads, scalpel and other surgical instruments. Chizinski held a fin out of the way as Bajer chipped off several scales before making an incision in the flesh large enough to insert a six-inch long radio transmitter device with an antenna coming out the end. In short order, Bajer was stitching up the fish. Gently, he picked it up and set it in the shallow water, as Chizinski and Casanova took turns gliding the fish back and forth in the water until it woke up and swam away.

“We have to be careful not to inflict too much stress on the fish, so it doesn’t perish,” said Bajer.

The radio transmitters have an estimated cost value of $6,000 each. Chizinski and Bajer tagged 10 Lake Lucy carp two weeks ago. So far they’ve nabbed and tagged seven Lake Ann carp. They’re shooting for 10. Then they’ll head back to Lake Lucy to try to re-capture the tagged fish. After that they’ll return to Lake Ann to recapture those fish, said Professor Peter Sorenson, architect of the research and leader of Sorenson Labs.

“We don’t know if there’s a carp problem in Ann or Lucy. We’re just trying to gather more data,” he said.

The research in Lake Lucy and Lake Ann is funded solely by the Riley-Purgatory Bluff Creek Watershed District.

Sorenson said the plan is to return to Ann and Lucy in the winter with hopes the tagged carp will lead them to the ever-larger carp population in both lakes, resulting in a massive carp removal, like those that took place last winter in Lake Susan and Lake Riley. Carp are known to school together during the winter. Several thousand carp were permanently removed from Lake Susan. Even more were removed from Riley, but many of them were returned, so researchers could study their movements throughout the year. They hope to re-capture and permanently remove the carp from Riley this winter, treating the populations on Ann and Lucy the same as they treated the Riley population last winter.

“This winter we’ll be removing more, as many as we can, from Riley. We should know what the problem with carp is in Riley,” said Sorenson. “We look at Lucy as the headwaters of Riley. The carp could be moving between the lakes. In Lucy we’ve found a moderate number of carp. We don’t know how many there are in Ann. Looking at Lucy and Ann is sort of like completing a puzzle.”

In August, Sorenson and Chizinski presented to the Chanhassen City Council some of the carp research undertaken by Sorenson Labs in area lakes over the past three years. That council gave them permission to use a motorized boat on Lake Ann to expand the research into Ann. Motors are not otherwise allowed on the lake.

Ha!

I speared a 30" carp outta Ann last winter. Do it again this year and it might be a $6000 carp. Yowzers!

[jwmiller33]

$6000 a piece????? holy CARP.... all i can say is i hope this solves the problem of how to get rid of carp for good, because otherwise, that is a lot of tax payers dollars down the drain... i guess wasting taxpayer dollars is something you have to get used to in this day and age
