The burbot (Lota lota) or bubbot is the only gadiform (cod-like) freshwater fish. Also known as mariah, freshwater ling, the lawyer, coney-fish, lingcod, freshwater cusk and (misleadingly) eelpout, the burbot is closely related to the marine common ling and the cusk. It is the only member of the genus Lota. For some time of the year the burbot lives under ice. They require frigid temperatures to breed.
