Liberalized Fishing


Recommended Posts

I think liberal,means not many.

Some times the DNR opens lakes up to permiscous(sp?) fishing.Lakes that the fish are dying anyway.

Permiscous(spelling)Means you can take as many fish and you can take them any way you want except poisons,explosives,or something else,but I cant remember what it is.

I was involved one time in promiscuous (sp) fishing and I think one of two things would happen:

1) The warden need only check with a warden by radio or phone in the area affected and then makes a judgement call.

2) It has been so many years since we did it, but I think the fins and gills were discolored (redish) from lack of oxygen.

3) My advice....forget the promiscous fish and find women that fit the same category smile.gif

Heard on KFAN tonight from the DNR Fisheries man Ron Payer (I think that's his name?)...anyway he stated that in normal winters they can "expect between 20 and 60 lakes to suffer winter kill, so they are opened to liberalized fishing". However, this year there isn't even one lake that's suffering winter kill. He also said that normal levels at this time of winter would be around 2 (on some sort of scale they use) and that some lakes were still 6 to 8 on that same scale. I believe that was oxygen levels per million (or something like that)...

Needless to say, the oxygen levels are very high, so the fish are healthy at this time and not as lethargic as they would normally be...

I think (just my guess) that the lack of snow has everything to do with oxygen levels. The sunlight can still get though to the weeds that in turn produce the oxygen.Just my guess though.

Bigfoot is correct. Heavy snow blocks light, which inhibits submergent plant growth, thus preventing the plants from producing the oxygen needed for fish survival.

In fairly clear lakes with little snow cover, some types of aquatic vegetation remain green and produce oxygen all year.

Bigfoot and Stfcatfish are both right. Just one more thing to add. Lack of sunlight will eventually kill the aquatic vegetation. When that happens oxygen is used as the vegetation decomposes. The fish get the double whammy!

Most game fish require 5-6 ppm of oxygen to live. Only rough fish like carp can survive at below 2 ppm. Bull heads and northern's can also live at 2 ppm, but most other fish will be dead or dying. 20 years ago when I was getting an aquatic biologist degree from Bemidji State, they opened up a lake to promiscuous fishing. I remember the many large northern's coming to an open hole in the ice to get O2. We speared a dozen or so northern's that would have otherwise died and fed some "starving" college students for a couple of weeks.

    • I drive by that candy barn all the time its crazy how busy it always is. Ive lived not 5 miles from it for 49 years. Been there once.
    • I'm game to try anything but yeah, I'm not into a lot of fruit or sweety meats.  Plus we made our one trip a year down to the Big yellow candy store already this year. 😋
    • 🙄yea you lost me when you mentioned honey!!!!!! and honestly i'm not a fan of all those "extra"ingredients in my meats.....especially that high temp cheese......yucky!!!!   plantenbergs has all kinds of that type of stuff.......i pass, only get plain sausage and brats.   iffin i was still on the union payroll i would take ya up on that as i travelled through belle plaine on my way back from siouxfalls now and then!!!!! now that i'm on a srick budget......thats a long way to go fer a weinie!!!!!🤣
    • Take a trip down to Belle Plaine. I'll show you some good hot dogs.   Just made Minnesota style summer sausage (blueberries wild rice and honey) for thew first time today.     
    • i've lived in Richmond and now cold spring all my life. my brother ordered a half of beef from this place called Homegrown meats , had never heard of it. know why now, when i picked it up it was established in 2020.  its just south of browns lake at the intersection of 22 and cty rd 43.  nice little place.   he called both Plantenbergs and breagelmans in Richmond........they are 6 months out. Breagelmans actually referred my brother to this place.  he said it was cheaper also!!!!!   i'll be taking some venny trimmings to Mcdonalds in 2 weeks for summer sausage and sticks!!!!!   plantenbergs will get the rest for bologna and hot dogs!!!!! you cant eat other bologna or weiners once you've had theirs!  mcdonalds SS and sticks are also topof the line as far as i'm concerned!
    • Which one?  I've been trying them all around the cloud.  Just had Elk burgers from McDonald's Clear lake last week and Bison tonight.
