Genetic diversity?

[taxidermist]

Nice pics.

Color like that in people can vary alot. bio diversity is great as it normally adds hybred vigor.

Cutts are a subspecies of the Oncorhynchus as are rainbows. So what you are seeing is proababley nothing more than just a color genetic. Both fish are off the same branch of the tree so to speak.

Like horses even though you have papered AQHA horses sometimes a paint horse will crop out.

Pacific salmon fall into the close cousin branch of rainbows.

Not unlike Brown trout and Brookies crossing to make tiger trout.

Cutthroat will readily interbreed with the closely related rainbow trout, producing fertile hybrids. Cutthroat trout vary widely in size, coloration, and habitats. Though their coloration can range from golden to gray to green on the back, depending on subspecies and habitat, all populations feature distinctive red, pink, or orange marks on the underside of the lower jaw; usually the easiest diagnostic of the species for the casual observer. As adults, different populations and subspecies of cutthroat can range from 6–40 inches (3–100 cm) in length making size an ineffective indicator as to species.

A cutthroat trout (most likely a Bonneville cutthroat trout) caught on the Weber River of Utah.There are 14 subspecies of cutthroat, including:

Alvord cutthroat trout Oncorhynchus clarki alvordensis; possibly extinct. Named in 2002.

Bonneville cutthroat trout Oncorhynchus clarki utah

Coastal cutthroat trout Oncorhynchus clarki clarki

Crescenti trout Oncorhynchus clarki crescenti (not an actual subspecies, but a form of coastal cutthroat (Behnke 1992).

Colorado River cutthroat trout Oncorhynchus clarki pleuriticus

Greenback cutthroat trout Oncorhynchus clarki stomias (threatened)

Humboldt cutthroat trout Oncorhynchus clarki spp. (Behnke 2002)

Lahontan cutthroat trout Oncorhynchus clarki henshawi (threatened)

Paiute cutthroat trout Oncorhynchus clarki seleniris (threatened)

Rio Grande cutthroat trout Oncorhynchus clarki virginalis

Snake River fine-spotted cutthroat trout Oncorhynchus clarki subsp. Named Oncorhynchus clarki behnkei, 1995 & 2002.

Westslope cutthroat trout Oncorhynchus clarki lewisi

Whitehorse Basin cutthroat trout Oncorhynchus clarki spp. (Behnke 2002)

Yellowfin cutthroat trout Oncorhynchus clarki macdonaldi (extinct)

Yellowstone cutthroat trout Oncorhynchus clarki bouvieri

Of course there's genetic diversity. shade and color of skin, length, girth...just like people. Myself, I tried to differentiate dialect. However when I catch trout and their mouth moves up and down, I can't hear them. We may never know, but other trout may hear them when they silently scream like that when we take them out of water and ther jaws move up and down as they are screaming in trout language. I tried to decipher once and I think he screamed "Stay away from the gray sowbug with the gold beadhead!!"

We'll never know for sure.....Don

Even many years ago before AGFC stocked cutthroats the Rainbows would have the so called Cut throat markers you guys are pointing out.

Most of these markers are simply part of the breeding colors also found on bows around the world to include many of the ones we caught in Europe.

First, Hybridization in trout is horrible to native populations.

Second you should probably post a link or a source when you cut and paste from an article, otherwise it is plagiarism.

Here is your link.

http://en.wikipedia.org/wiki/Cutthroat_trout

ok, first, why did you mention native trout? the nearest natives are the greenback cutts in colorado. no trout here is native so why care about hybridization (except crane mccloud redbands).

I for one would love to have a stream full of cuttbows in my backyard.

also, is any of this being published for personal gain? lay off with the plagiarism. he posted something informative that added to the conversation.

thanks for the info on cutts!

[retroaction man]

some of yall are worse then high schoolers
