What is my answer to this? Pretend to be a mystical person and latch on to some random features. One feature I have gathered regarding salmons is that they (supposedly) like pink/purple. Sure, sure, they can't see color but that's what the street tells me so I obey. Although I guarantee no success on the pattern, here's one tying episode:
Start with beautiful pink and purple marabou for a tail, and some orange ostrich herl for a body.
Tie in some flashabou to tempt the monster fishes hiding below.
Of course you need more beautiful pink and/or purple marabou.
Finish with some pizzazz of pink rabbit fur.
And this colorful monstrosity is guaranteed to catch either fish or a snag in the river. Either way you'll have at least a moment of excitement!
