Gregsalmon,

Yes, it is legal to buy them, but make sure you get a receipt from the tribal fisherman. We might not like it, but they sell them all the time with no interference from WDFW.

Many years I buy hatchery coho from a Squaxin fisherman, put up the eggs, smoke or freeze the coho. Then I can release wild fish without temptation - whether or not I'm required to.

However, many times tribal fishermendo not take good care of their catch. Buyer beware.
