View Full Version : 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.

I disagree.

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?:cool:

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

Jim, I caught the little trout with an EHC which is hard to see in the photo.
By the way, was that you modeling those fancy Beretta clothes in Sporting Classics magazine ?

Rivergal--While I'm closely connected with Sporting Classics in a variety of ways, let me assure you that the River Styx will freeze solid before someone asks me to model much of anything. There may be some folks on this forum who are old enough and county enough to remember an old Shep Wooley song, "I Just Don't Look Good Naked Anymore." In my case, I don't even look good dressed anymore, such are the ravages of time, the toll of the years, the penalties of good living, and who knows what else?

Still, I think I'm falttered by a case of mistaken identity.

You need to catch some more rainbows. The park bows can vary from mostly pink to very little pink at all.

I've noticed that too and have wondered about it. I've caught them ranging from silverish with little pink, to olive color with vivid pink to somewhere inbetwen and pink on the gill plates. There does seem to be quite a bit of variation.

Wonder what causes that? I don't think it's the watershed as I've caught variations in the same pool.

The browns in the park also seem to have more vivid colors than the other wild browns I've caught out west.

Coloration in trout is usually determined by time of year (spawning season), food sources, genetics, and even gender (females aren't nearly as colorful as males during spawning season). I have seen some vibrantly colored stockers (mainly brook trout in the fall) but compared to wild fish, they're nothing.

Just wanted to make sure that this didn't come off sounding like I was a jerk. the coloration of all park trout, be it rainbow, brown or brook, vary greatly. Like Jeff and Tarheel said, color depends on several factors.

here's a good sized fish with those spots still visible. (1st pic attempt, not sure it will work)

caught that one somewhere high on wplp

Jim, there's a bluegrass version of that song, I believe the Moron Brothers did it. They play it almost every wed. night on 93.5's bluegrass night (a virginia radio station that comes in good in g'burg)
