The burbot (Lota lota), also known as bubbot, (rocklings).
Etymology
The name burbot comes from the Latin word barba, meaning beard, referring to its single chin whisker, or barbel.[7] Its generic and specific names, Lota lota, comes from the old French[8] lotte fish, which is also named "barbot" in Old French.

With an appearance like a cross between a catfish and an eel, the burbot has a serpent-like body, but is easily distinguished by a single barbel on the chin.
Geographic distribution
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.[9] An anadromous population also lives in the brackish waters of the Baltic Sea.[10] Recent genetic analysis suggests the geographic pattern of burbot may indicate multiple species or subspecies, making this single taxon somewhat misleading.[11]

Life history
Burbot reach sexual maturity at between four and seven years of age.[17] Spawning season typically occurs between December and March, often under ice at extremely low temperatures ranging between 1 and 4 °C. During a relatively short season lasting from two to three weeks, burbot spawn multiple times, but not every year.[11]
As broadcast spawners, burbot do not have an explicit nesting site, but rather release eggs and sperm into the water column to drift and settle. When spawning, many male burbot gather around one or two females, forming a spawning ball. Writhing in the open water, males and females simultaneously release sperm and eggs. Depending on water temperatures, the incubation period of the eggs lasts from 30 to 128 days. Fertilized eggs then drift until they settle into cracks and voids in the substrate.[17]
Depending on body size, female burbot fecundity ranges from 63,000 to 3,478,000 eggs for each clutch.[11] Rate of growth, longevity, and age of sexual maturity of burbot are strongly correlated with water temperature; large, older individuals produce more eggs than small, younger individuals. Eggs are round with a large oil globule, about 1 mm (0.039 in) in diameter and have an optimal incubation range between 1 and 7 °C (34 and 45 °F).[11]
Newly hatched burbot larvae are
Burbot transition from pelagic habitats to benthic environments as they reach adulthood, around five years old. Average length of burbot by maturity is about 40 cm (16 in), with slight sexual dimorphism.[18] Maximum lengths range between 30 and 120 cm (12 and 47 in), and weights range from 1.0 to 12 kg (2.2 to 26.5 lb).
Diet and predators
At the larval stage, month-old burbot begin exogenous feeding, consuming food through the mouth and digesting in the intestines. Burbot at the larval stage and into the juvenile stage feed on invertebrates based on size. Under 1 cm (0.39 in), burbot eat
Commercial significance
A book written in 1590 in England notes that burbot were so common that they were used to feed hogs.[19]
The burbot is edible. In Finland, its roe and liver are highly regarded as delicacies, as is the fish itself. An annual spearfishing tournament is held near Roblin, Manitoba. One of the highlights of the tournament is the fish fry, where the day's catch is served deep-fried. When cooked, burbot meat tastes very similar to American lobster, leading to the burbot's nickname of "poor man's lobster".[20]

Conservation status
Burbot populations are difficult to study, due to their deep habitats and reproduction under ice. Although burbot global distribution is widespread and abundant, many populations have been threatened or extirpated. Ichthyologists and taxonomists are strongly advising to look into the old taxonomical due to new genetic insights there are two species of burbot: the European burbot (Lota lota) and the North-American burbot (Lota maculosa).[24] As the burbot lacks popularity in commercial fishing, many regions do not even consider management plans. Pollution and habitat change, such as river damming, appear to be the primary causes for riverine burbot population declines, while pollution and the adverse effects of invasive species have the greatest influence on lacustrine populations. Management of burbot is on low priority, being nonexistent in some regions.[25]
The Kootenai tribe of Idaho and their partners engaged conservation efforts to the burbot populations.[26]
