I know there are a lot of variables when it comes to fish growth rates, but I just wanna throw this out there.
I caught a walleye that i estimated to be about four, four and a half lbs. I tried to release it, but it wouldn't go after quite some time of trying, so I kept it. When I fileted it, I found it to be male. And by looking at the guts, particularily the sperm, It seemed to me that it would have to be a pretty old fish. It had the big hump back and everything. I took out the cheeks and they were at least a half an inch thick. It was caught in Last Mountain Lake Saskatchewan which is a large, deep, natural lake. Would anybody be able to make an educated guess as to how old this fish is? I didn't get any measurements or anything, but it seemed short for how thick it was. Any ideas on this? thanks.
