Stocking Lakes/Slots

14 posts in this topic

Here is a thought or question...We stock lakes because some lakes can't naturally reproduce right? If that is the case then why release 20-28" walleyes? If these fish can't reproduce what is the benefit of having them in the lake. Do we use them for eggs to stock other lakes then? Just curious..

I don't think its that some lakes absolutely cannot reproduce but I think some lakes just don't reproduce as well as other. So for this reason it is best to put the largest spawning fish back as not to put additional strain on a lakes walleye population.

I'm pretty sure there are a few lakes that just can't reproduce, and which get some fairly heavy stocking.

Assuming the fish can't reproduce, the benefit from letting any fish go is so someone else (or yourself if you're lucky) can catch it at a later point in time. I realize that for a lot of walleye fishing, the goal is a dinner at the end of the day, and not just some pictures and memories of a great day on the water, but practicing CPR at any level helps reduce the stress put on a fish population.

It's a pretty old argument and I'll put my take in. When I fish, generally any eye over 20" goes back in. If it's a slow day and I get on 21" I may or may not take it. Now, if it's withing the legal limit to keep and you want to keep a fish, then keep it. What I set as a standard for myself doesn't mean you have to. Keep what you want as long as it's legal. If it's a smaller lake though and you keep everything, don't expect it to keep producing in a couple of years to come.

its thier to help maintan good fishing in most lakes. not to increase population. the live ratio on fry is very good so when you see 30,000 fry dumped in that number is almost extint if you watch that year class grow to eaters.

The lakes that are stocked that don't have any natural reproduction don't have those slots. Minnesota's main walleye lakes have a 17-28" protected slot to protect spawners. Females generally reach sexual maturity around 17 inches and their performance tops out around 28" (there are exceptions to this rule). I think you're talking about two different lakes. The eggs taken on Cutfoot Sioux/Winnibigoshish for example, might go to Lake X/Southern MN lake, where there is no slot. Meanwhile the Cutfoot/Winni slot is in place to always have a nice stock of spawners.

Very well said dachise! As he said, the lakes that have the slots usually do have a decent spawn.. Lakes that dont, usually dont have slots. Lakes that have Northern Slots often have those to protect them to keep the smaller fish in check.

Sandman,

It is that attitude that is making me favor putting a slot on Cass Lake. Since there is no limit on size you are getting tons of people who are keeping both immature small walleye (12-13") as well as the big girls (20+). This makes for some up and down years and I have talked to quite a few people who fish lakes with slots and they say the fishing is just outstanding. I would not mind only taking home 3 or 4 fish a day if I was catching 100 or more fish. The problem comes when you fish all day with very few bites and you have people start panicing and keep the dinks. I guess the only way to somewhat prevent that is to legally force them to do so. If they choose to keep the dinks, they may run into a DNR boat with a pad full of tickets to issue!

Just my .02

The overall goal is to try and keep the population in relative balance. A population that has alot of large individuals but a relatively small number of young fish (recruits) is just as problematic for a fish manager as a population that has lots of small fish and very few large fish. Whether its the lack of natural spawning or extremely heavy fishing pressure, stocking and slots are tools that are used to try and keep things in balance. The problem is its a pretty subjective science and when you throw in the other variables such as forage availability, varying spawning conditions from year to year due to weather, and changes in water quality, the goal is definitely a moving target......

I agree with you windy. I honestly wouldn't mind seeing a slot of 15 to 20" across the board with one over 26". I think that makes a pretty good slot. At least that is what I practice out side of keeping one over 26.

Sounds like a plan, Sand. Now if only we could get the DNR to take a look at Cass. I know quite a few locals and guides who favor that. We may need to start a petition or something. I caught a 23 inch deep golden beauty this year, got my quick photos and let her go to make more babies! I think the slot might have to be bumped up just a bit, I think the optimal one would be anything under 14 goes back in, no questions asked, you keep the 14 to 19 inch fish and everything but one wall hanger goes back 20 inches or more. Sounds like we are both on the same page!

This is a discussion that we have several times a year. An across the board slot would be a disaster as different lakes have different needs to keep a "balance." There are some lakes that the best way way to improve the overall walleye population is to keep the small ones and let the 17 inch and over ones go. Lakes that have a problem with stunted eyes such as Island and Crocodile in the Arrowhead come to mind.

Slots work very well where they are needed but they are not needed everywhere. The DNR does a fine job in my opinion. Where we start running into problems is when the politicians start messing with the science.

As far as keeping small walleyes or large ones for that matter "panicking" has nothing to do with it. I would be willing to bet that I release more walleyes than most people catch over the season. That's not bragging it's just the way it is. However, if I determine that a walleye is not going to survive after it's released I generally keep it regardless of size. I've never seen it but I've heard that there are a lot of "floaters" on lakes that have a strict slot and a lot of pressure.

Gun,

I'm with you on that, I would keep a fish that I think is not going to make it, why be wasteful, but if it is small enough then it would be a free lunch for an eagle or other feathered friend and that is cool on the eco cycle in my book as well. I know that my grand daughters (who are 7 and 8) feel bad when they guy hook a 5 inch perch and it does not swim away when we toss it back but I show them the gulls or eagles and they watch it swoop down for a snack and they seem to feel better knowing that the bird had lunch that day, LOL !

The benifit of releasing big fish is more than just spawning.

Release big fish to catch big fish.

Most anglers care about size, and to have a good population of big fish(any species) on a pressured lake(almost all metro) practicing catch and release or selective harvest will makes a huge difference.

    • Murphy’s Law   I went out this afternoon trout fishing.  I questioned the wisdom of fishing on a robin’s egg blue sky day.  Trout shun sunlight.  I went outside to check the weather. The warmth of the afternoon coaxed me out of the house.     I fished a stretch I have done well on in the past.  I knew because of the bright sun I would more than likely not do well on big trout this outing.  Trout do not have eye lids and shun bright sun. When I got to the stream the outdoor temperature was 58 degrees.  I took the water temperature and it was almost 50 degrees.  That is well within a good temperature range to score some trout.     I hit the water at 2:45pm.  The sun was high in the sky and not a single cloud was in the sky.  I knew from experience that days like these I typically fished the shaded side of the stream.  There was no shaded side of the stream.      The fishing was tough.  I had lots of follows and flashes at my lure.  None seemed to want to commit.   I decided to look for cover for the trout.  I decided anything to throw a little shade on the trout would make them feel comfortable.     The trout had lock jaw.  I decided to target broken water so the trout would feel secure and come out in the bright light.  They still were bashful.  I decided another trick was in order. I was going to throw in the biggest snarly messes and let the lure drop to the bottom and give it a tweak to start the blade going.  Bang bang and I was in business.  This only worked in deep runs and i lost a few lures throwing into the mess.     I ended the outing with 24 brown trout to hand. The biggest was about 16 inches.  It was 5:30pm.  I usually get out at a bridge and today was nothing different.  I stood on the bridge looking upstream.  There was a sweet log jam just upstream of the bridge and it was in shadows.     I decided i was going to go just upstream in the shadows and cast a few more times. I was still on the bridge looking upstream. I looked at my reel and there was a loop on the spool.  This loop needed to be cast out if I was going to continue fishing.  I decided the bridge afforded the best angle and no trees in the way to cast out the loop in my spool.     I cast off the bridge.  The loop caught and dropped my cast about 15 yards upstream.  It nearly didn't land in the water.  It hit tight to the bank and I had a big snarl in my reel.  I looked down and saw my panther martin was barely in the water.  I decided to pull off some line and get this snarl out.  I made even a bigger mess.     I sat down on the bridge rail and started to mess with my giant snarl.  I again looked at my lure and it was barely in the water.  I was worried about losing the lure because of the snarl.  It was safe and barely dangling in the water.     I  really made a mess with the reel.  I was cussing it and trying to untangle it.  I lost focus on my lure in the water. I was peering over my glasses and really putting all my attention on this mess and I heard a splash sound.  I looked upstream and saw nothing.  I looked back at the reel.  I heard a louder splash and looked over the bridge at my lure suspended in the water.     My mouth dropped open wide and I stared in disbelief.  Me messing with the line caused the lure to jig up and down in the water.  This attracted a predator.  Not 2 inches from my lure was a giant trout suspended and staring at the size 9 gold panther martin deluxe waiting for it to move again.     My reel was still messed up so there was no battling this huge female trout on my reel if it decided to quit dancing with my panther martin and eat it. The bridge was at least 15 feet off the water and the idea of battling a monster trout from above was not appealing.  I worked frantically on the snarl.  It got even more messed up.     My fighting with this reel and keeping one eye on the giant female was nerve racking.  She still was very interested in my lure.  She circled it like a shark.  It was more than I could stand.  I decided if I hooked up with her with this less than optimal circumstances I would lose her and maybe kill her because of the bridge nonsense.     I decided to try to catch her another day.  The reel was non functional and i grabbed the line and lifted the lure out of the water.  What happened next is going to be relived in my dreams for the rest of my life.  The monstrous female brown bum rushed the lure as I lifted it out of the water.  It launched itself out of the water snapping at the spinner.  It was a swing and a miss. I got my wits back together and thought about cutting out the snarl and trying for her. I decided a return trip was on the agenda.  As I write this recollection I smile and cuss my circumstances.
