DREDGE fish finder

A DREDGE fish bites only in its own water, at its habitat depth and in its time window, and only with a method your gear supports; a fish of any hour bites by day and by night. In the base game, a rod over Shallow water in The Marrows at night reaches Grey Eel, Black Grouper, and Stingray; The Iron Rig adds Osteostracan.
