What are the walleye eating?

[Prkr314]

A picture would be most helpful, but I am guessing that with this high water temperature, you may be seeing individual disarticulated vertebrae from whatever bait fish they ate. If not, perhaps the gill cover from small fish, the gizzards from shad or depending upon the size of the fishes in question, lucky stones. I cannot image a walleye with any type of mollusks in them.

So just for conversation, My fishfinder marked more walleye than I've seen in more than a month in the area that I fished Saturday and this morning. Usually if they're not on the bottom your going to catch them, and a lot were up in the water column mixed with what looked like some kind of hatch, but none of the fish caught had any fish remnants in their stomachs....and they weren't biting like what i'd consider good for the amount of fish marked there. We didn't catch many junk fish or any shorts. On my finder, it marks walleye with yellow centers if the walleye have any size to them, which is what we caught, 18-22" fish ....wish I took a screen shot to show what I'm talking about. Friday evening we caught our walleye down by Crane Creek and they didn't have that gold color to them and didn't see what looks like hatch on the finder. Also didn't have many of those spiny fleas on our lines there, but did East of Kelly's. I guess that's where I'm heading with this topic, are the walleye eating those fleas? do those fleas have some sort of shell at some point?

I have absolutely found zebra muscles in lots of fish. Not large muscles but small softer ones. There was always lots of shell grit and flakes that were easy to identify. Mostly in PumpkinSeeds and Perch. A walleye and a perch are not that different and are of the same family if I remember correctly.

I spent over 30 years professionally engaged in multiple fisheries studies and running ice charters on Lake Erie and have opened and checked thousands of walleye stomachs. I never saw mussels in any of the walleyes that I checked for stomach contents on the clock or while filleting them for myself or customer's catches. However, I have seen Zebra (or Quagga) mussels in the stomachs of thousands of other Lake Erie fish species including: Freshwater drum (Sheepshead), Lake whitefish, Yellow perch, Pumpkinseed sunfish, Bluegill, Smallmouth bass, Round goby, Channel catfish- but never Walleye. When Freshwater drum eat mussels, their skin often takes on a shade of gold, compared to the usual silver/gray hue. If there were indeed mussel shells in the walleye stomachs, my theory is that they are inadvertently eating mussels as they inhale Round gobies from the rocks, but not deliberately seeking them, like the other species mentioned are known to do. Take pictures next time!

Hageman, Last weekend was the first time fishing East of the islands in months and I just thought it was interesting that there was a large number of walleye on the east side of the islands that didn't seem to be hungry. Normally when I mark a lot of walleye and they don't bite, it's because they're full of something( with the exception of a storm front coming). In the spring they'll have a half dozen shad in their bellies and latter in the summer I've seen what looks like perch as big as 10" in their stomachs. This weekend no half digested fish, just a kinda gritty almost small shell like stuff. And the a totally different shade of fish than the ones west of the islands. I always thought of walleye as predator, and wouldn't expect them to eat Zebra Mussels.

Are you goin to get back into ice charters. Got my largest eye fishing with you several years ago. Loved to lady where you put me up with she had grate stories.

When I retired from OSU, I tried for 2 years to continue by renting a house each winter, but we didn't get ice. It is too expensive and logistically difficult to run my business model without living there. I don't have enough storage space, am not there to throw a net when the shiners are around, my primary Bed & Breakfast now closes for the winter, my helpers wanted to move on and I wanted to fish more. So, I sold off the surplus shanties and duplicate gear and now just go there all winter to fun-fish. If we get ice, this winter and well into the future will be fantastic. I am glad to have helped you score on your personal best. I lost mine at the hole! She probably would have gone 13-lbs+.
