This is another submission from the Department of Yes There's A Word For That, and from their standpoint, it's a pretty good one. Me, I have no idea how or, especially, when I'd use it. Note that despite the apparent plural formation, this is a singular noun, though I've no idea what the plural form might be. From Latin halieuticus, pertaining to fishing, from Greek, from halieuein, to fish, from hals, the sea lit. salt.
We know the ancient Greeks wrote halieuticses -- Athenaeus gives a list of titles, none of which have survived.
