Joe, the "Will O' the Wisp" I posted may not be the song sought; that is why I didn't post it here. There are other tunes- see sheet music at American Memory. No way to be sure about this tune.

Google-
Look up "bankoories" and clippings at NOAA about fish market arrivals and prices includes one "Salt bankoory handline cod $4 per cwt" -but scanning the articles, I found several "Salt bankdory handline cod,..." but none with the spelling "bankoory."
The song could be about these salt cod.
