I found this interesting thread about what anglers find in the stomach of walleye.
I'd be curious if the biologists can confirm that stomach acid is different (more acidic) than other fish as the member states in his post. He feels the prey in a walleye stomach turns to liquid much faster than bass or other fish. Possible?
I have to believe the GBH on my property must have super digestion. He can pack a huge goldfish bigger than his neck down his throat and somehow not gain a pound and still feel hungry enough to keep hunting for another treat.
Looks like in this post the conclusion is that if there is content left in their stomach that they like small BG, YP, certain kinds of (soft) crayfish, gobies and any kind of minnow.
Walleye stomach contents John, would love to hear updates on how they are doing. You likely won't see them again for a while but maybe you will catch them somehow in the spring.
