Title: Determining a Walleye's Age
Post by: walleyeslayer1978 on Jan 06, 2011, 03:29 PM
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.

If you still have the fish carcass you can take out the otolith, dry it out and age it like you would the rings in a tree.

In 2007 i caught a 27" female that had a back tag. I sent in the information and recieved the fish's tag information back. In 1997 she was tagged and she was 17". So i figured about 4 years of age at 17", and add 10 more years at 27" she would have been a 14" year old fish. If i would have know more about the age i would have thrown it back to see another day.

yes, but it was a female right? I'll read the article, maybe it will tell me, but aren't the growth rates different for females and males? I imagine a five pound male would be equivalent to a ten pound female, seeing as the females get much larger. Also, don't you have the slightet twinge of guilt in keeping a fish thats so old?  I hope she's on the wall.

The thing with walleye is that females will grow longer but male generally grow faster.

And yes i would have definitely thrown her back if i knew.
