FNP-
Doc I wasn't attempting to pull anyones leg. I realize that coho have white fin tips but notice I was talking about adult chum. I remeber reading in a couple adult keys about the white fin tip and like I said I have never seen an adult coho with the same white tip that chum have. Not sure that your pictures with the pale edges are the same as a tip. The fish picture that Bob posts looks more like a tip but not sure about those white dots/drips.

First chance I'll do some more checking (suspect that several of us maybe looking a like more closely at some fish next fall). However as I often say our fish seem to be really adept at jumping out of boxes that we put them into. It may well be that this "white fin tip" is one of those boxes that fish jumped out of.

Best in the New Year
