[Local Hali Hunter]

Hi,

The last few springs that I have been privileged to land has had a yellow spot on its belly or underside.

Can anyone explain what this from?

Liver spots? We get some rainbows up in the interior with them.

As Scott says, this was explained back in 2010 on this forum: "The yellow spot is called a chromataphore. A chromataphore is like a birth mark. If you look closely at a spring salmon, you can notice the gold pigmentation tones in its skin color." As Spring Velocity notes, chromataphores are usually noticed on the bellies shortly before the fish return to spawn. Chromatophores are cells that produce color, of which many types are pigment-containing cells, or groups of cells, found in a wide range of animals including amphibians, fish, reptiles, crustaceans and cephalopods. Mammals and birds, in contrast, have a class of cells called melanocytes for coloration.

Thanks everyone for your answers. My apologies for not researching though the Archives, but I knew that the experts could not resist to explain.

These spots are very common on coastal Cutthroat trout in many VI lakes as well.
