Lota
1 species
The burbot (Lota lota), also known as bubbot, mariah, loche, cusk, freshwater cod, freshwater ling, freshwater cusk, the lawyer, coney-fish, lingcod, or eelpout, is a species of coldwater ray-finned fish native to the subarctic regions of the Northern hemisphere. It is the only member of the genus Lota, and is the only freshwater species of the order Gadiformes. The species is closely related to marine fish such as the common ling and cusk, all which belonging to the family Lotidae (rocklings).
Burbot have circumpolar distribution above 40° N. Populations are continuous from France across Europe and Asia to the Bering Strait. In North America, burbot range from the Seward Peninsula in Alaska to New Brunswick along the Atlantic Coast. Burbot are most common in streams and lakes of North America and Europe. They are fairly common in Lake Erie, but are also found in the other Great Lakes. An anadromous population also lives in the brackish waters of the Baltic Sea. Recent genetic analysis suggests the geographic pattern of burbot may indicate multiple species or subspecies, making this single taxon somewhat misleading.
Burbot live in large, cold rivers, lakes, and reservoirs, primarily preferring freshwater habitats, but able to thrive in brackish environments for spawning. For some time of the year, the burbot lives under ice, and it requires frigid temperatures to breed. During the summer, they are typically found in the colder water below the thermocline. In Lake Superior, burbot can live at depths below 300 m (980 ft). As benthic fish, they tolerate an array of substrate types, including mud, sand, rubble, boulder, silt, and gravel, for feeding. Adults construct extensive burrows in the substrate for shelter during the day. Burbot are active crepuscular hunters. Burbot populations are adfluvial during the winter, and they migrate to near-shore reefs and shoals to spawn, preferring spawning grounds of sand or gravel.
