Why do we stock lakes??

Recommended Posts

I was wondering why the DNR stock lakes? I was reading in a weekly outdoors magazine that a lake mentioned in southern mn had excellent reproduction along with other "smaller, pothole" type lakes. It got me thinking about how much stocking has been done on leech in the last 2 years, and I have come up with a theory...MONEY! It's funny how we chastise the government but then ask them to "provide" fish for out catching. Any thoughts...

There are many lakes throughout the state that need to be stocked or there would be no fishing for eyes at all. Not all lakes are good at nature reproduction or can reproduce enough to support the strain placed on the lake by the fisherman.

I have seen different specie stocked in lakes that do very well Sonicrunch. Some lakes just don't have very good reproduction for specfic species.

They do it because we demanded it. We keep putting pressure on the DNR to provide us with adequate recreational fishing. One method is to use the stocking program. As already mentioned, there are a great many lakes in this state that would not support any walleye population were it not for the stocking program.

Also, some of the more famous walleye waters see more fishing pressure than natural reproduction can support and there too the stocking program helps supplement it. Osakis is a good example. Once considered the mother lake because it supplied many eggs for use in the stocking program but today it sees so much excessive fishing pressure it now must be stocked. There are efforts under way to attempt to improve spawning beds in the hopes of restoring some of the lake's former glory but time will tell.

I do understand that certain lakes are not able to support natural reproduction of certain species, but dont really understand why. I assume it has something to do with the lakes water quality, structure, bottom content, predation, as well as sufficient prey fish. I'm sure its not this simple but why doesnt the DNR work on changing these attributes to support natural reproduction. I know fishing pressure has a lot to do with it also but is this approach too far fetched?

Some fish species simply cannot reproduce even in a lake that has good forage. It's not that they don't try. They do but without the right conditions it doesnt work. Add in a whole lot of other variables like weather, fish kills, fishing pressure etc then you get something quite complicated to manage.

Lets take for instance the Walleye. Old Marble Eyes need water that has good current & oxygen. River mouths inlets, outlets, wind, weather all play a part. If those requirements arent met the eggs arent able to hatch. Thats why you see eyes do well in rivers and large lakes that are Spring fed.

Panfish on the other hand are notorious breeders. Like the Black Crappie which can quickly overun other species in a lake. They do well whether it shallow & muddy, or clear and sandy. They don't require much except may the right spawning temps and beds for it to all happen. In certain topographical areas like lakes or ponds down in the Southern United states its possible panfish can reproduce several times within the same year.

Without stocking some of the body of waters cannot sustain a certain fish population. Or some waters may never even have that species of fish if not through the stocking program.

Why not just make it fit for reproduction? Number one reason? Its gonna have to be the cost or funds. Trying to obtain or change attributes of a lake without proper research can highly affect that lakes ecosystem and it chances of producing gamefish. It would also be disturbing what nature has shape it to be.

Bottom content also plays a role in spawning environment. Correct me if I'm wrong but I believe walleyes require relatively clean gravel bottom. They won't be successful if a lake only has sand or muck bottom. Panfish on the other hand might do well with this type of bottom structure.

I read about native fish populations quite awhile ago, if I remember right very few lakes in MN have "native" walleye, or smallmouth populations. Without stocking most walleye lakes would go back to being bass and pike lakes, the smallmouth would probably be okay. I think I also remember reading that tons of our lakes had trout before we started messing with them. I hope someone can confirm or deny what I remember.

The 'what does well where and why' is much more complex than most even begin to imagine. I have read a number of the research reports on the DNR HSOforum - http://www.dnr.state.mn.us/publications/fisheries/investigational_reports.html - and have learned that the variables are almost innumerable. I suggest that anyone interested in knowing why things might be the way they are go and read a few of these reports and you will learn a lot.

There will never be enough money to make any lake or stream 'perfect'.

You could have perfect conditions for a particular species but without spawning habitat you've got nothing. Changing the attributes to support natural reproduction...commendable intentions with disastrous results. If you try to add new habitat and it doesn't take, you've wasted thousands of dollars. Add gravel to a mud lake for walleyes to spawn on? It'll be silted over in no time. It really depends on the species, but if you want to make changes, work to improve shallow water habitats and replant or help recover native plants. Improve water quality and help prevent runoff that may turn the lake green or silt over those preferable spawning habitats. Bass and panfish need gravelly bottoms near vegetation. Pike need wetland complexes. The less homes you see on any given lake with some combination of sandy beaches, freakishly large docks, weed rollers, and rip rapped shoreline means the more likely you are to see native plant communities, natural buffers, and functioning ecosystems that support naturally reproducing fish populations. If you help recover some of the shoreline habitat and things revert back or the land is subdivided, platted, and sold into a bunch of lake homes, then you're back to square one with lots of money wasted. It's easier said than done. The state doesn't control the land and watershed (except in rare instances where they own most of the land), so they have little control over the water since land management decisions have holistic effects on the waterbody. If people want good fishing for the future, something has to be done for our lakes and streams in the uplands and on shore first. That means landowners have to make changes and the general public has to support changes to how our lands are regulated and monitored and exactly to what level of stinginess those regulations are taken to.

The bottom line is this.... The bottom LIne. People in MN want, for the most part, to catch walleyes, People who travel to MN want to catch walleyes. Most lakes, with a few exceptions, south of Millacs do not naturaly reproduce, that leaves half the state with no 'eyes. By stocking eye's in the lakes they make many people happy and make money in the long run.

Spend $$$ to make $$$.

    • Next up was installing the floor. We went with 3/4” marine grade plywood. I also coated both sides and all edges with a water sealer just to be sure.    After installing the plywood floor we put the furring strips in and ran the wiring.    Each wire goes back the front wall where I made a little panel. The front wall has an opening for a 55” TV that sits flush in the wall. The little squares above and below the tv opening are for in wall speakers.  This is half of the wires the other side of the panel has the other half.  This is all the positive wires coming through the front wall and behind the panel. I forgot to take a picture of the back of the panel after I cleaned it up and put the negative wires through.  Here is a picture of the front of the panel while I was booking everything up. All the positive wires on the left and negative on the right. My wiring is a lot different than most shacks. I’ve never made a panel like this before so I didn’t really know what to order. The terminals that the wires go into are called din rail terminal blocks the snap onto a little piece of aluminum called a din rail.  Later I found stackable ones that would have saved space but I like how it turned out. Each terminal block has a slot in it where you can put a jumper. So everything that was going to be on one switch would be jumpered together. Things on a different switch would be jumpered and so on. The terminal blocks have a hole on the top where one wire comes in and gets screwed down to hold it and there is the same on the bottom. So once the terminal blocks are jumpered to things you want on the same switch you only need one wire out the bottom. Things that were ran off of the switch went out the bottom and over to the relay board. You do the same for each thing you want to run off a different switch just run a wire to a different relay. The long green rectangle thing on the right is a relay board. Our house has 12 light switches not all of them are used yet but they can be so I bought a relay board with 12 spdt relays. The green square on the left is an arduino which is basically like a mini computer chip that you can program. I’ll explain more once I get to what our switches look like. The bottom right of the panel is for the trailer lights and brakes and all the stuff that hooks up to the truck.  I eventually replaced these normal terminal blocks with the din rail style.  Here is the wiring panel all finished up.  The reason for using all the relays and arduino was so I could use this light switch and eventually be able to control everything from a smart phone. In the fish house we have 2 of these switches which each have 6 buttons on them. Each switch has a set of cat 5 cable running to it. One set is connected to the atduino board and sends a signal saying the button was pressed.  The other cat 5 wire is to send a signal to turn on and off a little light next to the button when it is pressed   Here is the back of the switch. So basically how it works is the arduino has pins on it that can send or receive signals it also has pins that can send 5 vdc or 3vdc. So one wire from the arduinos 5 v pin hooks up to the back of the switch where it says sc (switch common 5v coming in). A different wire connects a different arduino 5 v pin to the terminal that says pc (pilot common which is just the little lights next to the buttons). So when a button is pressed a brief 5 v signal is sent from the arduino to the switch which goes through board on the switch and to the wire terminal that is for that button the signal is then sent back to a digital pin (receiving pin) of the arduino on a digital pin. The arduino has to be programmed to receive different signals on the pins you want. Once the arduino sees that a button was pressed it sends a signal over to the relay board saying a button was pressed close the relay that corresponds to that button. When the relay closes it allows the 12v to go to whatever you want to turn on. The nice thing about how this system works is everything can be changed in a matter of minutes. Say I wanted to have the ceiling lights be on button 4 instead of 1 you just have to change a couple of numbers in the code and plug the arduino into your computer and upload the updated code. I’m sure I lost most people right away and I’m not sure if anyone else would even want to do something similar but If so you can message me and I can try and explain it better. Before this I’ve never done anything like this so I had to learn all of this online and how to write little bits of code and do all that which was fun but also frustrating at times since I didn’t have anyone to go to with my questions.  Not sure If this video will work or not.  4B8EE058-806B-4BF6-8DD8-8FC76BE46BD0.MOV  
    • Everything is going strong now. Been making salsa for the last week or so, have been doing abt's with the jalapenos,  thinking on letting them go red to spread it out a bit. The early girls are kicking em out but the big boys have a bit. Canned two jars of pickles with more coming down the pipe, but I'm gonna hafta start grilling some zucchini,  can only make so much bread.    Bell peppers seem to be running a little on the small side, starting to change colors but was hoping for some better sized ones for stuffing. Snap peas did good out of the gate but are trailing off already,  ya gotta love this time of year!!
    • juicy or freeze dried?
    • Most of the state has been experiencing sunny, warm, and beautiful summer days. The forecast predicts some rain over the next day or two, but otherwise it looks like warm temperatures and clear days and nights. Canoers at Mays Ledges at the Brule River State Forest.These mild and sunny days have been great for canoeing and kayaking and many river water levels are moderate and perfect for paddling. The lower Wisconsin Rivers is running just about normal for this time of year, with many sandbars popping up.Much of the state has been hovering at moderate fire danger this week, which means, in the right place, wildfires can happen. Nearly 60 wildfires have occurred across the state in July, mostly caused by fireworks or sparks from equipment. .
    • Looks to me like a great fishing cart...mount some pole holders on the sides and a cup holder for your beverage and life is good!!🎣
    • i still have some from 2016, most from last year yet but i like to stay ahead. how do they say it........i like to let them MELD!!!!!!!!!😁 that was a 1/2 bushel, smaller batches makes it not so over whelming. especially on a work nite. 
    • Nothing better then homemade pickles. We did 84 quarts last year but the kids didn't eat all of them so we are going to skip a year.
