I was wondering that myself, but when our administrator moved it here instead of deleting it I figured it was OK to continue.
From ice fishing for cusk,
"Who are these brave people and what are they fishing for? They're after cusk, burbot, ling or lawyers, depending on your preferred namesake – few freshwater fish species are addressed by so many common names; “cusk” is the most commonly applied moniker in New Hampshire. The object of attention is the only freshwater member of the codfish family, which bears resemblance to an eel possessing a broad head and enormous mouth.
New Hampshire is blessed with cold, deep, natural lakes that have sustained the native fauna in their deep basins since the retreat of the glacial ice sheet ten to twenty thousand years ago. The cusk is one of our native fishes, and flourishes right under the noses, or "feet", of many anglers who have never seen or angled for them".
