Hunk of hardwood in the shape (somewhat) of a fish, like the piece of wood in the picture below: The fish is bonded to the rim to reduce the amount of soundboard area to the rear of the bridge in the high treble. This increases soundboard stiffness by the mere fact that the soundboard is thus smaller (which is generally beneficial in the high treble) and eliminates excess high treble soundboard area that appears to be of no value (and in fact appears to be detrimental to piano tone and soundboard longevity). Note to Ron Nossaman and/or Del Fandrich: I feel comfortable talking all about how to build this stuff, but I lack confidence when I start to talk about the how and why this or that affects a belly system. If my two sentences above are faulty, please point it out for the benefit of all (especially me!).
