    Can someone post a fish wieght calculator according to length and girth measurments for Walleyes. I usually don’t wiegh the big fish that I release, but I do measure them. I just recently caught a walleye that was 29inches long and 16 1/2 inches around. I’m kind of curious as to what she wieghed.

    i have always wondered how much weight should be added to those conversion charts this time of year when them big girls look 9 months pregnant – at least a pound i would think.

    That’s why I believe you need a lenght and girth measurment. If she would have been spawned out, she wouldn’t have been as big around and wieghed less.

    I have always used the Length*Girth*Girth/800 for muskies (for long cylindrical fish) to be something that will get me close. Your’s calculated to 9.9#’s per this one.

    Its interesting that once you get to 26″, as an estimate, its 6#, 27″, 7# and so on.

    fat girls usually have quite the bellies on them. i caught a 24″ fish this fall with a 16″ belly. it weighed 7.5 lbs. so these are def guidelines and not sure things.

    P-4 Walleyes are off/over those type of charts… I had a 29 7/8″ spawner scale at 11lbs 14oz last April.

    I have to think it would go close to 12 lbs. I caught a 29 incher in Pool 4 last year that weighed 12lbs even . I pulled a late fall 28.5 out of Pool 14 that went 12.1 lbs. The big girls I’ve caught out of pool 14 this year are carrying a lot of weight I think it would be real close to 12. I hope I find her tomorrow I’m taking a personnel day to fish pool 14. Congrat’s on you trophy.

    I agree that the weights on the river are very hard to calculate. I have been involved in 2 personal bests down there. Myself with a 28.5″ that went 10.50# and a 27.5″ that went 11.50#. It has been some time, need to get into another
