Jim, fish art, yes indeed! Those are yellowfin tuna. I got that on a trade (Alpine car audio product for the framed art) from the artist, in Hawaii. It's a Japanese art style, but I can't remember the name of it. It begins with crinkled rice paper, then take the actual fish and paint them with a black carbon watery substance, lay the fish on the rice paper and that creates a silhouette of the fish. The artist then colors in the fish with water colors. It's quite unique and goes well with combining two of my hobbies, offshore fishing and high-fidelity music systems (and music, of course).
Sorry to be long winded, but I am rather enthused with it and wanted to share the story.
