Sounds like you got a kelp greenling. You do know that if it looks like the shape of a bass, then you got a rockfish, if it's slim like a lingcod, you got a greenling. You mention greenish spots... you sure they weren't bluish? Were there spines in the dorsal fin and on the gill plate? Was there just one lateral line or 4 lateral lines? Was the head disproportionately bigger than the body?

If you don't have a clue what in the world I'm asking you you can look up this dude, Dr. Milton Love. He co wrote a book called, Rockfishes of the Northeast Pacific Coast. It's a fantastic reference book that even a fisherman would find VERY valuable. Excellent photography for the most part.
