    Sorry GFS - I thought you were saying they took the heads because of the yellow dot being a hatchery mark.

    if you fish for trout you will catch trout!! if you fish for steelhead you might catch steelhead!!

    I've seen the same yellow dot on landlocked rainbow trout. I really think it's naturally occurring. The Feather River fish that they took the heads from likely had an adipose clip.

    ghost, I'll ask the UCD person who does the genetic hatchery stuff for the feather river hatchery about it, but I think they will give me the same info as above?

    We shall see,

    Good info to get out there for sure.

    Haha. Me too!

    Next time you (or anybody) gets a yellow dot salmon get some pics of it, cut a chunk of fin off and contact me. Maybe we can put all of the samples to work and do a genetic association study to see what's going on...

    Best,

    This came up on the Sniffer last fall. Salmonid nailed it. It's a naturally occurring spot - current theory leans towards some kind of lipid concentration in the fish for reasons still not known. One thing's for sure - it not a mark from the hatchery.

    Yellow Spots on Chinook and Coho Salmon

    Anglers often notice distinct yellow marks that are circular in shape and are often found on the belly near the pelvic fins. Because fisheries professionals use artificial dyes or ink to mark fish, these circular-yellow marks found on Great Lakes Chinook salmon are often misidentified as an artificial mark. However, these marks are not artificial marks used by fisheries professional to track salmon in the Great Lakes, but instead they are naturally occurring in Great Lakes Chinook salmon. These circular-yellow marks are usually noticed in late July through early September as a salmon undergoes the process of maturating and preparing to spawn. In general, there is a good deal of variation in Chinook salmon coloration especially as they start this metamorphosis and are staging prior to running the rivers. What is really unique about these marks as the fish starts to turn from a silvery-white to a yellowish-brown in color is that the areas beginning the change can appear as a perfect yellow spot or circle about the size of a quarter. Again, these spots are naturally occurring pigmentation and not an artificial dye or mark used by fisheries professionals.
