MN DNR Gill netting in front of resorts.

I just got a warning that there was a 250 ft gill net in front of my launch while I was on the way in with my group. I would have certainly gotten them with my lower units and had injuries. 10:00 at night in the dark.

Ya fricken STUPID!

I will be lodging a certified, official complaint with the Department of Natural Resources in the morning. And the Department of Labor AND OSHA.

(They're trying to snag all the fish they tagged.)

So, Brainiac DNR, the ONLY thing you have accomplished, is you just killed off a LOT more walleye for NOTHING!!!!!

I'll let everybody on LSF know what they have to say for themselves.

Remember the words of George Carlin..........

Just think of how stupid the avergae person is, and then remember that half of them are stupider that that.

Thanks for all you do up there FP!!

I called Large Lake Specialist for the MN DNR toay and talked at length with him about last night's events. Here was his reply to some of my concerns:

Jon,

Thanks for your call earlier today. Sorry to hear that you and Nate had some concerns about the location of the recapture gill nets. I double checked the positions of the gill nets that were set just west of Hunterís Point last night. It looks like the net was set about a half-mile offshore from where the Hunterís Point Resort ramp is located and the net was being fished from a depth spanning 16 ft. to 20 ft. deep. Because our nets are constructed to be 6 ft high and they fish along the bottom contour of the lake, that specific net set would have had a minimum of 10 feet of water between the float rope on top of the net and the waterís surface. We have a general rule that we set these gill nets in at least eight feet of water so that if a boater inadvertently finds themselves going over the net, they wonít get their lower unit entangled in the sampling gear. In the rare event that a gill net is set shallower than eight feet of water, the sampling crew remains in the immediate vicinity to prevent any potential issues with navigation. Further, the marker buoys for our DNR nets are constructed with orange flags that stand about three feet from the water surface and are lighted at night to mitigate any potential hazard to navigation. Please let me know of any additional cost-effective measures you might come up with to further remedy concerns with boaters getting entangled in our sampling gear when crews are tasked with night sampling with this type of gear.

You also asked why weíre conducting a mark-recapture survey. The following link should take you to the press release that was issued and that should hopefully fill you in on most of the pertinent details. If you have additional questions that arenít covered in the press release, please feel free to give me a call.

You also requested the number of walleye that were killed conducting this study. Because our population modeling is sex based, we do keep track of the sex ratios during the recapture event. In order to do this, we do need to sacrifice a small proportion of walleye to obtain the ratio. Listed below are the numbers of walleye that had been taken over the last several weeks to obtain the sex ratio of fish in the recapture event:

Week 1 May 21-23 139 walleye
Week 2 May 29-31 123 walleye
Week 3 June 4-6 149 walleye
Week 4 June 11-14 191 walleye

That would total to 602 walleye over the four week period, which I would currently guess to be about 10% of all fish observed in the recapture event. We did donate the dead fish to the VFW, an elder care facility, and Disabled American Veterans.

I canít provide you with the 2018 population estimate you requested because weíre still collecting the data and it will likely be several months before the final product is available. The past walleye estimates are listed below:

2002 1,100,000
2003 630,000
2004 450,000
2008 736,000
2013 256,000
2014 249,000


Please feel free to give me a call if you wish to discuss anything further.

Regards,
Eric

To follow up on some of the stuff I went off on, heretofore will be referred to as concerns, Eric Jensen, Chief Fisheries Biologist for the Minnesota Department of Natural Resources followed up on the complaint I made to him.
You can't stay mad at this guy.
Anyway here was a follow up to some other concerns I had beyond the 300 ft gill net thing:
RE: ML mark-recapture study

Eric,

Thank you for your timely response to what we talked about, Eric. If you get the results of the 2018 population estimate survey and remember my e-mail, weíre all anticipating your finding.

Will do! If you havenít heard anything by the end of August, just give me a quick reminder Ė unfortunately, I seem to be getting more forgetful as I get older.

We have a really smart guy from Simon Fraser University calculate the final point estimate for us. The simple Petersen estimator is actually relatively easy to compute, but the guy we use is pretty sophisticated with these mark-recapture studies and he has several different ways to make the estimate depending on the various assumptions that need to be considered for the different models. Based on how we sampled and how the fish mixed in the lake, he will figure out the best way to make the most accurate estimate. The only problem is that he is internationally renowned and is often traveling about the world working on various projects, so it sometimes takes a bit of time before he can get into the guts of our Mille Lacs PE. Hopefully he can get to it sooner than later.

Have a good weekend,
Eric

Not really sure what to make of it. Obviously placing nets near highly travelled routes and at night does not seem good. I am at Fishers and have wondered what the DNR was doing with big tubs of nets as I have seen a few boats lately.

If they are following the advice of this so-called fish expert and he has a proven track record, I can kind of understand why they are trying it. But any wasted fish, when we can't keep anything certainly gets my attention.

Like you said, hard to stay mad at the guy if he is being honest and transparent. Where are the population estimates for 2015-2017??

Appreciate your efforts Fishnpole!!

Why do we, the land of 10,000 lakes and state of the walleye, need to hire a "world renowned" fish expert to give us an estimate of the walleye population? I thought we had the best and brightest already working at the DNR, or at least that is what some other members have been telling us.
