The burbot, also known as "ling" or "freshwater ling," is a unique freshwater fish. It is the only freshwater species in the cod family. Although less sought after for sport fishing than walleye or pike, the burbot attracts anglers with its delicious flesh and intriguing behavior. It is particularly active during the winter months, making it a popular target for ice fishing in Quebec. Widespread in several regions of Quebec, it can be found in the Saint Lawrence watershed, Lake Saint-Jean, and several northern rivers. Its fight is not the most vigorous, but its capture can hold surprises, especially in winter when fishing options are limited.

The burbot has an elongated, cylindrical body reminiscent of eels, with a wide, flattened head. Its color ranges from yellowish-brown to dark brown, often mottled with darker spots, allowing it to camouflage well in rocky and sandy bottoms. Its skin is smooth, covered with small scales that are almost invisible to the touch. It is distinguished by its long dorsal fin and anal fin that extend over most of its body. Its mouth is wide, with a prominent lower jaw and small teeth. Young burbots have more pronounced patterns than adults. During spawning, males may display slightly brighter colors to attract females.

The burbot is widely distributed in the freshwater of Quebec. It is found in large watersheds such as those of the Saint Lawrence, Lake Saint-Jean, and Lake Mistassini. It is also present in several northern rivers and in colder, deeper lakes. The burbot prefers cold, oxygenated waters, which explains its predominance in the northern regions of Quebec. However, it is absent from warmer, shallower waters, such as those in southern Quebec where water temperatures often exceed its preferences.

The burbot favors cold, deep, and well-oxygenated waters. It is often found in rivers with moderate currents, deep lakes, and areas where the bottom is rocky or sandy. It prefers dark spots, often hiding under rocks or in cavities during the day. In winter, it migrates to the deeper parts of lakes, where it remains active under the ice. The ideal temperature for the burbot is between 1 and 10 °C, which explains why it is more abundant in the northern regions of Quebec.

Burbot spawning occurs in winter, typically between December and February, when water temperatures drop to around 1 to 4 °C. Females lay their eggs on rocky or sandy bottoms, often in crevices or cavities to protect them from predators. The eggs hatch after a few weeks, giving rise to larvae that feed on zooplankton. Young burbots grow quickly and reach sexual maturity at around 3 to 4 years of age. Their lifespan can reach 10 years under good conditions. Spring: rapid growth of young → Summer: foraging in deep waters → Fall: migration to spawning areas → Winter: spawning and activity under the ice.

The burbot is primarily a solitary fish, although it may gather in small schools during spawning. It is not particularly territorial but prefers areas where it can easily hide. The burbot is less sensitive to noise and light changes, making it less wary than other species. It is more active at night and during low-light periods, primarily hunting by ambush. Weather conditions, such as overcast skies or light rain, can stimulate its feeding activity.

The diet of the burbot varies with its age and the season. Fry primarily feed on zooplankton and small aquatic invertebrates. As they grow, their diet expands to include small fish, crayfish, aquatic insects, and sometimes amphibians. Adult burbots are opportunistic predators, feeding on whatever is available, including dead fish. In winter, their feeding activity increases, making them easier to catch during ice fishing.

The burbot is a prime target for winter fishing, as it remains active under the ice. In spring, it is less accessible as it stays in deeper waters. In summer, it becomes harder to locate as it hides in shaded and deep areas to avoid the heat. Fall is a transitional period when it begins to migrate to its spawning areas. In winter, ice fishing is the most effective method for capturing it, especially in overcast weather or at night, when its foraging activity is most active.

To attract the burbot, especially in murky water, prioritize lures with bright or phosphorescent colors. In clear water, natural colors mimicking fish or crayfish are more effective. Lures that produce vibrations, such as wobbling spoons, can also stimulate the burbot's interest, especially in dark depths. In overcast weather or at night, use luminous lures to maximize visibility.

To fish for the burbot, a sturdy 6 to 7-foot rod with medium to heavy power and moderate action is recommended. An open or closed face reel capable of holding a 10 to 20 lb line is ideal for withstanding deep fights. Use hooks sized 2 to 4, depending on the size of the bait. A 20 lb fluorocarbon leader can be used to withstand the burbot's teeth and friction against rocks.

The burbot has a slippery skin, so it is advisable to use a towel or gloves to handle it. For release, ensure to let it go quickly and gently, holding it by the belly to avoid injury. For a photo, support it well under the belly and avoid holding it out of the water for too long.

Natural predators of the burbot include large fish such as pike and muskellunge. Birds of prey, such as the osprey, may also target young burbots, especially in shallow waters.

The burbot is not considered an endangered species in Quebec. Its population is stable, but recreational fishing is regulated to ensure sustainability. It is important to respect catch and size limits, as well as to practice catch and release whenever possible, to preserve this unique species.
