I caught a yellow trout in a western Oklahoma pond that is stocked yearly with rainbow trout from Arkansas. Are these yellow trout common? We have fished this pond regularly through the trout season for three years and this is the first of this kind we have seen.

Yellow and wild-colored rainbow trout were first used in crossbreeding experiments to determine the pattern of yellow color inheritance. So what you have is the yellow phase of a rainbow. The color phenotypes are explained by a system of two gene loci with two alleles each. The yellow color (allele a) is caused by absence of the dominant allele A controlling wild color. Among the yellow fish (aa) the second gene locus allele B controls palomino and black eye color. Albino and red eye color (allele b) is caused by the absence of the dominant allele B controlling color development. It's like they say. "It's in the genes."
Something coming out of the hatchery no doubt.

you can find a discussion of golden trout and some pictures over on the Northern Virginia Trout Unlimited bulletin board. look at "Fishing Reports", page 2 of "Holmes Run", or copy and paste this link to that page. look for Durcel and Bob B's posts and the pictures that follow.
and you can look at Gaudy Trout in this forum, under General, for some other ideas.
Jason, i hope it's kosher to send folks to other fora. if not, lemmeno and i'll stop. the internet has opened up such an amazing interconnectedness of knowledge that it's really tempting to add to the connecting threads. as the postings multiply, it's hard to keep track of just what we read where and when.

Yeah, it's fine. Lots of webmasters are touchy about that, often because they're insecure about their own site's ability to hold onto its members. I don't buy into that kind of territoriality: I try to attract people to this website by improving it, rather than by crossing my fingers and hoping they don't find somebody else's site. That kind of paranoia reflects a poor understanding of the Internet.
I completely agree with you about interconnectedness. It enhances a forum because it makes more information available as food for thought and discussion.
