I read an article once that had approximate water temps for game fish spawning by species. Does anyone have those figures or approximates for Vermilion?

I have watched male northerns in the weeds by our cabin in late April-early may and know suckers run early may but never thought of checking the temps.

Not to sure on the exact temps but I believe the pike start spawning under the ice followed by the walleye then the suckers... should be able to find all the info on the DNR website.

Pike can spawn in water as cold as 38 degrees, Walleyes want it a bit warmer in the 42 to 48 degree range.

Bass and Muskie want it in the 50's, before they start to get active. Around 55 degrees, is the magic number for Muskies.

Smallies and largemouth bass like it in the 60 to 65 degree range, however they will spawn at cooler temps, if they have to.

The cooler the water temps are the lower numbers of eggs will develope into fry. Cold spring water temps can really have an adverse effect on how well the eggs develope and what percentage of the fry survives.

On opening day of walleye season last year, with ice covering most of Big Bay, the water temps were 38 to 41 degrees in the areas I fished. Even in the tournament the second weekend, temps had only mitigated a few degrees. The 'eyes were still stacked in many spawning areas...

On muskie opener and through the first 10 days or so, I still saw females cruising with one or two males beside them. I didn't fish for them around their spawning areas at all...Instead I concentrated my efforts on open water trolling, until the water temps warmed and the fish recovered from spawning.

They'll get pike in the fish trap on the west end, as soon as the water starts to open up in the creek, while the rest of the lake is still locked up tight.

The spring of 2004 was unusually cold, and the conditions persisted well into the summer. It was a terrible year for walleye eggs and fry, and the result was a very poor year class.

It was also one of the most unusual years I've experienced for muskie as well.. The summer peak occurred a bit later than normal. We barely eclipsed 70 degrees for a week to 10 days during the summer, but the temps lingered in the 60's through September. We had a great 3 week night bite from late September until mid October, and then a good casting and trolling pattern that lasted until mid November.

Nothing unusual about the casting and trolling pattern, but that late September to mid October pattern was unreal that year! The cooler summer water temps were also easier on the fish than the super warm water temps of the next couple seasons.

The weather after the spawn is very important to a successful year class. If unusually cold conditions persist into the summer, it greatly hampers fry production. Even in years with early ice out, it's the weather that follows that's the biggest factor in spawning success.

      This is a darn good practice!

      When I left there last Thursday, I had my boat as high as it would go on the boatlift. When boats would go by too close it would rock a little bit, so I tied the 4 cleats to the lift.  I might have to pull the darn thing off and park it around the corner at the neighbors dock while I'm there. With my rocky shoreline, I can't leave it tied to mine, it gets the crap beat out of it from boat waves. I'll have to pull it when I head home....that means removing the canopy on the lift, what a bummer. Who would of thought this could happen when the water was so low this spring!!!

      On the FB page, people are reporting more than 5" of rain from today's storm.
    • SkunkedAgain
      I saw the rain forecast and then zip-tied all of my dock pallets to the steel dock. Of course, I only do one side so that if the waves start popping the pallets up, they will just lift and fall back down instead of floating the entire dock up and down.

      Nice fish! Any rain total updates so far? Getting a bit nervous about our dock boards

      On the south end...   The walleyes are biting!  A great week of fishing with a combination of jigging and pulling spinners the go to methods.     Most walleye fishing is taking place between 21 - 24' of water.  When you locate fish on your electronics, either anchor up and jig or simply drift with spinners and crawlers (or troll if there is no wind) through the schools.   When jigging, gold combined with a bright color such as glow white, pink, orange or chartreuse is a hard combo to beat.  Use a fathead minnow, rainbow or a frozen emerald shiner.     When hooking the minnow, it is helpful to hook the minnow through the mouth and out the gills, pushing the minnow all the way up the hook to the jig head.  Re-hook the minnow as far back as possible.  This will catch the short biting fish.    Use a two ounce bottom bouncer with a two or three hook snelled spinner and a nightcrawler.  Some good blade colors are gold or gold combined with gold, orange, glow red or pink.   As happens most years in June, another good walleye bite fired up in various areas of the south shore in 5 - 10 feet of water.  Oftentimes, minnows spawning pulls in hungry walleyes creating some excellent fishing.     Some big walleyes over 30 inches being caught, along with the eaters, smalls and slot fish between 19.5 - 28 inches that must be released.   Anglers can keep a combined limit of 6 walleyes and saugers.  Up to 4 can be walleyes.  All walleyes 19.5 - 28.0 inches must be released.  One fish over 28 inches may be kept. On the Rainy River...  The river is flowing with a strong current.  Consequently, fish are being found in areas just out of the current.     Jigging with a minnow is effective when you are on fish.  Otherwise, pulling spinners and trolling crankbaits along shoreline breaks against the current in 6 - 12' of water is producing a mixed bag of walleyes, saugers, pike, smallmouth bass and an occasional crappie.   The Lake Sturgeon season opens July 1st.     The river is a great summer option with 42 miles of navigable river and many nice boat ramps.   Up at the NW Angle...  The fish are snapping up at the Angle.  Another great week of fishing amongst the 14,552 islands in these parts.     Minnesota waters are producing nice walleyes. Some fish being found off of deeper structure.  Some nice opportunities are shallow based on forage, hatches, minnows spawning, etc. Pulling spinners with shiners or crawlers has been effective.  When you are on "a spot on a spot", jigging is the best technique.     Trolling crankbaits is working well and is a nice way to cover water and put your lure in front of a lot of fish.     In addition to walleyes, saugers, pike, jumbo perch, crappies, pike and smallmouth bass are also in the mix.   Muskie anglers caught some nice fish this past week.  No specific pattern as the cold spring has fish still settling into summer.  The lake boasts a healthy population of fish, many in excess of 50 inches.

      I'm catching them on bobbers and leeches.  Try fishing smaller side bays on the edge of some rocks but not in the rocks.  Fish in about 6 - 10 feet of water.  The bite starts about 7:30 pm till 9:00 pm.  I also noticed a few may flys hatching in the areas I'm getting success.  I think they're coming into the bays in the evening to feed on the mayflies.

      Generally I agree with your assessment Gimruis. Nobody likes a nanny state, but the harsh reality is that without rules and regulations far too many people take advantage of limited natural resources. There are those that will never follow the rules regardless, as well as those that don't recognize that as more people catch more fish, we all need to keep less.   I've eaten a few SM in my life, and they taste just as good as a walleye or northern. However, I would bet that 80% or closer to 90% of all people catching SM practice catch-and-release. Therefore I am not sure what a slot is going to do in this specific situation. Maybe the DNR has some good theories but I doubt the main culprit is the number of large SM being kept for food. I assume that it is a contributing factor but not the main one.
