    Last Saturday I caught a tagged flathead.18″ of fun…Anyway it had a tag and sent the info to the person doing the research,here is the info he sent me…
    The fish was tagged on 8-30-2011; in the Chippewa Falls Flowage and was 15.1 inches long and weighed 1.31 pounds.
    I don’t know if that represents a typical cat’s growth rate… Paul

    Doesn’t surprise me. I think most people think fish grow faster than they actually do.

    I can just see Brian coming back with a yong of the year reply.

    The growth rate for flatheads seems to be all over the place, some grow faster then others. But they still grow slow up here. We had a 22″ that was 10 years old. More the reason to let em all go if you like to catch the bigger flats

    Caught a 33″ last weekend on St. Croix. How old you figure it was?? Kinda crazy to think about. Fishing by myself so this was the best picture I could get.

    Its August, so that definitely has to be the young of the year.

    Not necessarily true about the up here part. They seem to grow slow all over. This was from a recent in-fisherman

    I was refering my statement towards the flatheads for the most part. Seen a florida dnr electro shocking study and they were getting flatheads of 50lbs and over that were 10-12 years old. From all the dnr aged tagged fish I’ve caught up here and seen results of others catches that were 10-12 years old these fish ranged from 8-20lbs that’s a pretty big differance.
