    Default Trout Question

    I have always noticed that when I catch smaller trout they often have “elliptical” spots running the length of their body (rainbows and brooks specifically) I just assumed that the spots go away as the trout gets older or larger. I was wondering if there is an age at which these go away or is it more to do with diet or even time of the year?


    Here are some pics showing what im talking about

    I'm 90% sure that second rainbow you posted is stocked. It doesn't have the colors of a wild fish. They're called parr marks though, and they go away with age. Kinda like fawns lose their spots.

    I disagree.

    I think they are all wild fish. I can't recall ever seeing a stocked rainbow with white tipped fins. The markings are called parr marks which usually dissappear with age. Some species of trout retain the markings.

    Look at it's fin next to it's gills, there is damage. And it's far too silver. Most wild rainbows I've caught are really pink.

    This is a rainbow that I caught in the park that has very similar characteristics. Based on the location I caught it at, I'm 99.99% positive its a wild fish. I think their colors really depend a lot on their diet, and I don't mean insects v. dog food. But yes, most mature rainbows I've seen don't have much in the way of parr marks.

    Jason--Like you, I disagree. It appears to me to be a wild fish, although admittedly the coloration is less vivid than is typical in 'bows. The white-edged fins are something I've never encountered on hatchery fish. The "thumbnails" or parr marks seem to vanish on 'bows at about the eight-inch mark and on specks at about seven inches. They are a juvenile coloration, but I'm no scientist so I have no idea of exaclty when they disappear, age-wise.

    Rivergal--Just one question. Is that a tulip poplar seed fly sticking out of the corner of the trout's mouth?

    If so, I've got to add some to my fly box. Do you have a pattern?
