According to various WCO's, Pyme walleye fry have a < 1/10 of 1% chance of a survival rate which is exactly the reason Ohio and PA stock them. Don't take my word for it. Ask any WCO there or go to the hatchery in Linesville and ask. CNR is fine, but one needs to keep it in context. CNR for wallyeye at Pyme isn't going to make a difference other than making some people feel good about upholding their personal fishing philosophy and I'm not "blasting" them for doing what makes them feel good. Just don't be judgemental [I'm not implying that anyone is] about anybody keeping their legal limit.
I fished Pyme with various people that I didn't know on Easter day. Total walleye was 8, one 15" and the rest were 20-22". This was all from shore and methods tried were vertical jigging, bladebaits, bait with float and stickbaits. 1/2 of the people were locals and the other half were not. 6 people with an average of 10 hours/ person = alot of effort with little return. This is an actual account of the day. I had heard from a WCO that other people at other spots on the lake did better.
