I fish panfish and walleyes in the Minneapolis chain of lakes where muskies are regularly stocked. Normal size is very small and stocking is necessary to maintain the walleye population. Furthermore I am having increasing trouble over the past few years finding bait shops that can stay open.

I credit that to two top sized and essentially unnatural predators. Humans and muskies. First humans take a huge number of smaller panfish especially from the shoreline reducing the number available to grow to larger sizes and muskies in these smaller waters take larger panfish as they increasingly orient to open water in sizes larger than the smaller native pike are able to. This applies to walleyes, also, and certainly perch both of which increasingly orient to open and deeper water as they grow. The panfish populations are receiving a double whammy, getting hit on both ends of their growth cycles.

Every panfisherman I know has relatively frequent run-ins with muskies stealing hooked fish, that goes all the way up to two and three pound walleyes, and all of us who use artificials have lures as small as 1/32 ounce taken by muskies up to the high 30 inches at least and I know for a fact that 50+ muskies will take hoked walleyes up to at least mid teens in length, because I have seen that more than once, too. Occasionally we win one of those contests, like I did last April involving a 38" musky on ultralight with 4 pound test. Now that certainly is a thrill, but far more often we get cut off. Last summer I had something like over a dozen such cutoffs, just fishing for crappies on ultralight. I know some of them were direct takes of my tiny lures, because I saw the musky take the tiny jig in its own right. So I know that muskies feed from that size up to what they call decoy suckers which are the size of respectable eater walleyes in many cases, because I have seen it quite a number of times. IOW they feed on just about everything in their environment. Even in such small waters as the Minneapolis chain of lakes, they grow rapidly to outsize any naturally occurring predator. All smaller species are adversely affected by a change in natural predator/prey formulas. In short we are not going to get decent populations of larger panfish or medium sized walleyes and probably pike, too, no matter how we manage them as long as musky populations in those lakes remain abundant.

Quite a number of fisherman I talk to are increasing dissatisfied with the emphasis that the musky elite has been able to get the state to make on their special quarry. That includes a lot of average musky fisherman, too, BTW.

Those lakes still produce an occasional 30" walleye and pike and outsized largemouths. Those that survive to the larger sizes are still present, but the medium sized walleyes and pike are not there in the quantities they should be any more than the larger sized panfish. I have seen virtually no pike under 24 or 25 inches. The smaller ones, which include many of the males are virtually never taken, which is quite different from most natural pike waters. The largemouths are more oriented to weedbeds and so we can probably thank the milfoil that their populations remain passably complete.

My belief is that muskies have been overstocked into many inappropriate waters and that should be curtailed. Additionally I think that musky management should be restricted to native, natural musky waters, allowing year around catch and release in all others. In native waters management should be intensified to protect the natural populations. Not just muskies either. Muskies are present in a lot places and I am not advocating extermination anywhere, but releasing extraordinary protections where those fish did not naturally occur will benefit all other parts of those fisheries. In those other places, that year around access will also benefit our struggling bait shops who get important income from outsized bait sales to the current musky pursuit. The December 1 closer, as it now stands, may put some of them out of business, and they are too few and far between now.

BTW I would also like to see more intensive panfish management with minimum sizes and decreased possession limits for perch, bluegills, and crappies, allowing more of the younger fish to grow to the size where they start to move to open water. I have no doubt that declining populations of yellow perch in our chain of lakes is due to lack of an effective top size on native open water perch predation, and that means muskies. Adding muskies is simply too much predation on perch populations, which are open water oriented throughout much of their life cycle. They are too important as a forage fish to continue to allow 40 in possession.

I would also like to see sales of a specific catch and release additional license stamp that allows a one additional rod or hook per fisherman, for catfishing, trolling in medium to shallow levels, etc, but not applicable for trout or on specifically designated waters or for specifically managed fish in particular waters. Catch and release is a relatively mature fishing technique and should be more widely available. I would have no problem limiting particular tackle, either, such as requiring circle hooks for bait to increase the likelihood of successful release or requiring the cutting of line for deep hooked fish. Catch and release fishermen are very likely to pay attention to such requirements. That increases DNR revenues and puts less pressure on populations which should also decrease stocking needs.

Right now in musky stocked waters that also get walleye stocking, pretty much what we have is walleyes stocked to be heavily musky forage. Non-native muskies are every bit the drain on such walleye stocks as the cormorants are on some lakes.

There are far too waters where muskies were stocked that were and still are inappropriate. Lots of such local fisheries for other species have been damaged.

I meet with the DNR several times each year, primarily on Walleye related items, but other species are discussed as well. It seems the direction is already been set to protect and promote the pan fish populations, both in select waters, and statewide. An emphasis is being discussed to protect the genology of 'large' panfish.

The Muskie fans are active and passionate. I'm sure you'll find resistance to reducing the efforts they've put forth.

The multiple line issue is always discussed, but it is an uphill battle. There is not alot of support. We did discuss the potential of controlled, multi-line regulation possibilities. ie - experimental regulations.

It's interesting you feel catch and release is common. While I believe it is in the western part of the state, the concensus is we are a ways from seeing that activity on a regular basis statewide.

Interesting study was done in a small area - I don't have the paper with me, but the results were something to the effect Walleye were harvested 83% of catch frequency, Pike 27%, Bass 7%, and Muskie less than 1%.

How about a new advertising campaign, "Minnesota's best tasting fish -



















the Muskie."

First thing I'd like to mention, what if any is factual info your spouting? Any of it? If so, I think it would be helpful to all to back up with studies...something to back up your claims.

There are less than 100 muskie lakes in the state, that's a pretty small percentage wouldn't you agree? Studies have been done on the effects of Muskies on panfish populations, one of the bigger studies was done by, I believe Wisconsin stout?? in conjunction with the WDNR. The study was done a lake that was overpopulated with panfish, they introduced muskie in hopes it would make a dent...it didn't help the overpopulation at all. Why? Joe fisherman with his preconceived ideas said it would take care of the issue, no question!! Turns out they were wrong.

Part of your argument is skis should only be in natural ski lakes. Do you feel the same for walleyes? How about trout?

You use the statement, "muskie elite", you sound like a panfish elite. The difference is those "muskie elite" are teaming up with the DNR to do studies on the effects the lunge has on other fish populations. They are finding few if any negatives.

You say the muskie is every bit a issue on walleye stock as the Cormorant?? That must mean it has little effect!! It's funny you bring that up...I recall the shooting of many, many cormorants on one of MN premier walleye lakes(leech). The reason, the Cormorants were killing and eating all the walleye fry. The end result was terrible walleye fishing, at least that's what the Leech association wanted everyone to believe. Those killed birds were examined, the study showed 1%- 3% of the stomach contents were walleye fry. How does that add up?? To top that off, the walleye fishing is as hot on leech right now as anywhere else. They're catching fish of all sizes, how is that possible, in a few short years, the walleye population is now abundant?? We're not talking fry, we're talking keep-able fish and those in the protected slot. The lake had a few down years, everyone blamed the birds, now the facts are out...it had little if anything to do with the cormorant.

The fact is, muskies aren't the downfall your making them out to be. It's the mystique of the lunge that makes people believe what your spouting...it's certainly not the facts.

Muskies...causing bait shops all over the metro to go out of business. LMAO

my dad always told me that it was the muskies eat up all the other fish. they dont live off the weeds. whenever we catch em, we just dry dock em like carp.

I am not a musky fisherman. However if the decision came up I would choose the big game fish over the bait fish any day! If you want to catch baitfish go catch them out of your goldfish pond :)

You people do realize that while muskys do eat some walleyes and panfish that does not make up the majority of there diet? They would much sooner eat suckers or other soft rayed fish and REALLY LIKE BULLHEADS. I can gaurentee you that walleye eat more walleyes then muskys do so using your logic if you want more walleyes you should be killing all the walleyes you catch.

Thats just it. All the studies I've read suggest that Muskies do more good than harm to panfish & walleye populations. As mentioned the Muskies help control & prefer the species that directly compete with the more "desirable" species. Namely suckers, carp & bullheads. And if the population is out of balance it's because of poor fishing practices, such as only keeping the biggest panfish & not releasing the spawners (common & widespread). Then they help return the balance by feeding on the most abundant food source, the overpopulated, stunted panfish.

Chances are if the panfishing is crappy it's from fishermen over harvest & lack of foresight. Kind of like eating the seed corn mentality.

And all the old school thinking of muskies being the culprit still live on today. Some of the locals on a nearby lake used to sabotage the DNR traps & kill the muskies in them then go around bragging about it. About the same mentality as the troll post. And some people feel the same way about pike & bass, and any other species people see as a threat to their favorite. More than one type of elitism out there.

But this is a good post & subject. I'm glad somebody (no1son) brought it up!

No question that angling pressure suppresses the size of panfish.

Here that angling pressure has declined as the panfish size went down and as the local musky population matured to sizes substantially over the maximum size of the local pike.

We see muskies all the time, and there are always musky fishermen out offering suckers, but the number of times I have seen muskies bypass suckers to attack hooked panfish is as high as
one 24 hour period last year in which I personally had them bypass suckers to attack my hooked crappies and walleyes some 8 times, involving more than one musky and resulting in two successful steals. Not a sniff at any of the suckers, including one terrified bait fish offered directly in front of the musky's snout. She was a big one, too, measured at over 50 inches the one time she laid along the dock so her length could be marked. She got one of my walleyes that evening. She came around to "visit" quite a number of times last summer and was never interested in suckers, but did steal some panfish, including one bluegill put down illegally as bait, which she took immediately and then cut the jokers line since he wasn't using steel. That guy got told in no uncertain terms he would have a talk with a warden if he ever pulled that stunt again, too. We haven't seen much of her this summer for some reason. Some of these fish have been caught multiple times on steal leadered suckers and are obviously sucker shy. They don't take the panfish on a run either, but more often just swim off shaking their heads until one tooth or another catches the mono. Around here I see more muskies fishing crappies and walleyes in just one season than most musky fisherman in other places see in years. We identify individuals and some of them even get names, and usually polite ones, too.

One of the problems for smaller waters is that muskies not ony grow faster than native pike, they grow much larger in the same waters. In fact, the limitation on pike size that normally limits trophy sized fish to larger deeper waters with high energy deep forage, does not seem to apply to muskies who can make maximum sizes on general forage. Like the queen of the lakes I mentioned above, they can make 50 inches on a panfish forage base, and that is a trophy nearly anywhere. Around here we see them passing up suckers and taking panfish both hooked and free ones.

The studies on native lakes with native populations are all well and good, but muskies in exotic environments do not necessarily behave quite the same. I and a lot of other fishermen around here can stand witness to that.

(Finally got past the logoff, guess I forgot to check remember me the last couple of times. At least I got forgot somehow.)

FWIW my tally over the last year includes high 30" muskies, high 20" pike, teen weight channel cat, 20"+ walleyes, 20" largemouth, 14" crappies, bluegills to about 8" (and assorted other sunfish and hybrids), sheephead, perch and bullheads, even rock bass and quite a few smallmouths, although only one of them actually even approached a couple of pounds; so they really did have small mouths, everything unguided and most from shore using live and cut baits and artificials with pretty much everything including all the largest released immediately. I use tackle classes from 2# ultralight to 40 pound superbraid. I pretty much fish for what I feel like on any given afternoon. Obviously no real trophies, but I think I am a pretty decent general fisherman, not hardly a specialist or "elitist" in any species. I like em all, even muskies (in their proper place, of course). That's what my thoughts on this are all about, anyway.

All good points. Every lake is different and I can see your concern on certain waters. In some ways I'm sure it's different here in Michigan. The natural population here is more limited & the stocking program, too. The DNR here does a pretty good job of selecting lakes for the Musky program. And they've also had to abandon certain lakes because of local discontent over the stocking. But almost invariably there's going to be somebody unhappy about them.

Here's a really informative article about panfish size & harvest. Took me a little while to dig it up but worth it. It brings up the points you (no1son) were mentioning earlier about putting some limits on panfish and why they get undersized in the first place.

Thanks mudpuppy.

That is a very good article. For years we have been following the assumption that overpopulation leads to stunting in both bluegills and crappies. My guess is that such a result definitely is part of the cycle and maybe the end of the cylce in very tiny farm ponds, but may not apply to larger waters that can come to a different balance.

Minnesota also has a few lakes where panfish restrictions are being tested both for bluegills and crappies and even one lake where all electronics are banned. It is not just Illinois that is testing the panfish restrictions.

For some time now knowledgable ice fisherman have been advocating fishing waters with less angling pressure for the larger fish, and it is certainly true that once a body of water gets a distributed reputation for large panfish that angling pressure increases and top size decreases, and that it is also well known that the largest fish in any body of water are more easily found on smaller bodies.

Illinois and Minnesota are certainly going in the right direction, IMO. Farther south a number of states have found that increasing fishing pressure and too liberal possession limits reduce the size of crappies in even very large premier waters, and they have had to rein in fishing pressure to maintain those fisheries.

BTW Minnesota has effectively stopped the introduction of muskies into additional waters, after having engineered a very successful recovery of the species in its native waters, which is extremely positive. They went on to introduce them into a about an equal number of additional lakes, however, where they were not native.

It is those additional waters that concern me. In those places consistant restocking has produced a heavy population of adult muskies that certainly do have an outsized predation effect on all available local forage with younger replacement fish also in place. With muskies capable or reaching trophy size in waters where native pike cannot, that is an additional harvest beyond fishing pressure that works against any possible forage species attaining maximum size.

I would like to see another step tested. That would be making at least some panfish bedding sites off limits to any angling while they are active, coupled with an increased emphasis on panfish catch and release over the rest of the year, which is quite doable. I guarantee that it is, even with live bait, and it certainly is with artificials. Actually where I fish, there are quite a number of parents who are introducing small children to fishing through catch and release sunfish. The kids are having a blast and quite naturally orient to not killing the fish.

As for the muskies there is no doubt in my mind that if humans as one outsized predator have such a marked effect, that muskies as another that is both protected and replenished are also having an outsized one in exotic waters. There is some natural reason that muskies are not native to all waters in their range, and I believe that is because they are too massive a predator for many of them.
