White Springs-where do they come from?

[Dirtdog67]

Without reading any farther deewar25, you need to do a little research into a basic text relating to the difference between shrimp and krill.. If you honestly think that flesh colour in a white spring is due to diet, you need some serious schooling.. These fish are unique to certain systems throughout coastal b.c. Why do you think the avg. size on white springs is size lg. These fish are mostly made up of remaining wild stocks that inhabit those unique streams..
As for the shrimp/krill thing, what do you think makes sockeye flesh so red. KRILL hands down-dirty

Yammy5 as a rule we do let the Tule's go. Many times we can identify them prior to the net and we are happy to release them at that point. However the less edjucated fisher-person may decide they want them anyway. I have only caught a few that were Chrome Bright and they smoked great. I have to agree that these are Wild Stocks. Maybe it would be good advise to leave them alone. That's a touchy one and I had better stay out. Usually when you are about ready to release a fish Ole' Man Seal shows and Gut's the thing in seconds flat.

Dirtdog....I wasn't sure which side was which...if Krill was responsible for white or pink......reading more, yes, it is pink, and according to this article, it is still undecided as to the cause....there is a case for diet, but just as big a case for genetics. You better get on the phone to the goldstream nature house then and tell them they better present both scientific arguments

Personally, I don't really care - meats meat in my books.

Most of the White Kings we catch on the Columbia are pretty far gone by the time they get here. Oh Yeah I am from Oregon. The Big Kings with the white meat we call Tule's pronounced Too-Lee. These typically get huge and you can always tell if you have caught one by the 15 pounds of snot they leave in your net. This is generally when they are really red on the sides. Sometimes they are harder to identify though, such as a Chromer that cuts White. These fish are ok to Smoke up and give away to freinds that dont fish. Good luck and don't forget the KoneZone's[8D]

Any "king" you catch that is really colored up is going to have white flesh. They use the pigment from their flesh to enhance their spawning colors.

The traditional thinking about flesh colour related to diet was due to the high levels of keratin in euphasids (shrimp and krill). It has been proven in farmed chinook and atlantics that a diet high in krill will enhance the red colour of the flesh, however this is only true of fish that are already 'pink fleshed' to begin with. Several experiments have been performed on white chinooks with high krill diets in controlled environments and it has not changed flesh colour at all.

I believe that the scientific community has pretty well established that the flesh colour is a genetic rather than diet controlled.
