The boreal skate, or Amblyraja hyperborea, is a species of skate that primarily inhabits the cold waters of the North Atlantic. Although it is not commonly caught by sport fishermen in Quebec, it piques interest due to its unique biology and its presence in the marine ecosystem. Due to its preference for deep, cold waters, it is mostly observed by marine biology researchers rather than recreational fishermen. Its distribution extends to northern Quebec, particularly in the Davis Strait and the Gulf of St. Lawrence, where it contributes to marine biodiversity. The boreal skate is a fascinating but non-combative species, making it more of a study subject than a target for sport fishing.

The boreal skate has a characteristic flattened body, with wide, wing-like pectoral fins that extend out to the sides. Its color ranges from brown to gray, often with darker spots that allow it to camouflage against the seabed. The ventral side is generally lighter. Its mouth is located on the underside of the body, typical of skates. The tail is relatively short and lacks a spine, unlike some other skate species. Young boreal skates resemble adults but are smaller, with more pronounced patterns that fade with age. Males are distinguished by claspers used for reproduction, visible beneath the body, while females lack these.

The boreal skate is primarily found in the cold waters of the North Atlantic, including the Gulf of St. Lawrence and the Davis Strait. It prefers depths of up to 1000 meters, making it difficult to observe for recreational fishermen. Its presence is more frequent in Arctic and sub-Arctic waters, and it is rarely seen in the coastal areas of southern Quebec. Its abundance is relatively stable in its natural habitats, although few precise studies have been conducted on its exact population.

The boreal skate primarily inhabits deep, cold seabeds. It is often found at depths of 200 to 1000 meters, where the water temperature remains between 1 and 5 °C. These skates prefer sandy or muddy bottoms where they can effectively camouflage. Due to their preference for deep waters, they are rarely encountered near the coast or in shallow waters. They are adapted to low-light environments, making them difficult to observe without specialized equipment.

The boreal skate reproduces oviparously, laying eggs encased in tough capsules often called "mermaid's purses." Spawning occurs in spring when conditions are most favorable. The eggs hatch after several months, giving birth to well-developed, autonomous young skates. Growth is slow, and it takes several years to reach sexual maturity, typically between 6 and 10 years. The lifespan of the boreal skate can reach 20 years or more under optimal conditions.

Timeline: Spring (spawning) → Summer (egg development) → Fall (hatching) → Winter (slow growth)

The boreal skate is a solitary species that spends most of its time camouflaging on the seabed. It is non-territorial and moves according to food availability. Relatively passive, it reacts little to disturbances such as noise or changes in weather. It is more active at night, during which it primarily hunts. Its ability to tolerate pressure variations allows it to adapt to different depths without difficulty.

The boreal skate primarily feeds on small fish, crustaceans, and mollusks that it finds by foraging on the seabed. Young skates mainly feed on small invertebrates and larvae, while adults prefer larger prey such as bottom fish and shrimp. In winter, when food availability decreases, it can survive on a more restricted diet, feeding on the most accessible prey.

The boreal skate is active year-round, but its feeding and reproductive behaviors vary with the seasons. In spring, it reproduces and actively seeks mates. In summer, it takes advantage of the richer feeding waters to feed abundantly. In fall, it begins to prepare for winter by increasing its energy reserves. In winter, it becomes less active and focuses on survival in deep waters where the temperature is stable. The best times to observe it are at night, although this is difficult without specialized equipment. Weather conditions, such as overcast skies or light winds, have little impact on its habits.

The boreal skate is not a target for lure fishing, but if you are looking to observe or study it, cameras with LED lighting can be useful for illuminating the seabed. Bright colors are not necessary, as the skate is more sensitive to movements and vibrations than to colors. In clear water, use soft lighting to avoid startling it.

To observe the boreal skate, a wetsuit suitable for cold waters is essential. Use full diving gear, including a mask, snorkel, fins, and a dry suit. If you are using an underwater camera, ensure it is pressure-resistant for the depths. A safety harness is recommended for deep dives.

Handling the boreal skate is generally not recommended due to its non-aggressive nature and vulnerability. If you must handle it for scientific reasons, do so with care, avoiding contact with its gills or tail. For a successful release, ensure it is well submerged and can swim away on its own. Take photos quickly if necessary, without flash to avoid stressing it.

Predators of the boreal skate include some large predatory fish like the Greenland shark. Seabirds can also prey on young skates when they are near the surface. However, due to their deep habitat, adult skates have few natural predators.

The boreal skate is considered a species of least concern by conservation authorities, but it is protected by regulations aimed at preserving marine ecosystems. In Quebec, there are no specific regulations for its capture, as it is not targeted by recreational fishing. Catch and release is encouraged for any accidentally captured skate.
