The short-tailed skate, Amblyraja jenseni, is a species of skate found in the cold waters of the North Atlantic, including parts of the Gulf of St. Lawrence. Although it is not a common target for sport fishing, it attracts the interest of anglers due to its unique appearance and ecological role. Encounters with this skate are often accidental when catching other marine species. Its distribution is mainly limited to deeper, colder waters, making it a challenge for sport fishermen to catch.

The short-tailed skate has a flattened body and broad pectoral fins that extend on either side of its body, giving it a disc shape. Its color ranges from brown to gray, often with dark patterns that allow it to camouflage against the seafloor. Its mouth is located underneath its body, typical of skates, and it is equipped with small teeth adapted for crushing crustaceans and mollusks. Its tail is relatively short compared to other skates, hence its name. Young skates are generally lighter and have more distinct patterns than adults. Males and females are similar, although males have claspers, appendages used for reproduction.

In Quebec, the short-tailed skate is primarily found in the Gulf of St. Lawrence and adjacent waters of the North Atlantic. It prefers deeper, colder areas, often beyond 100 meters in depth. Its presence is less frequent in shallow coastal areas, limiting encounters with recreational fishermen. Its distribution is influenced by water temperature and food availability, making it more abundant in regions where these conditions are optimal.

The short-tailed skate primarily inhabits sandy or muddy seafloors, where it can easily camouflage itself. It is often found at depths ranging from 100 to 600 meters, preferring cold and stable waters. The ideal temperatures for this species range from 2 to 10 °C. Fishermen targeting this skate should look in areas with weak currents where sediments are abundant, as it primarily feeds on small invertebrates that live there.

Reproduction in the short-tailed skate occurs through oviparity, with females laying eggs encapsulated in tough capsules often called "mermaid's purses." The breeding period mainly occurs in spring and summer. Young skates emerge after several months of development, already well-formed and ready to fend for themselves. They reach sexual maturity between 5 and 7 years and can live up to 20 years. Spring → Spawning → Summer → Egg hatching → Fall → Growth → Winter → Survival in deep waters

The short-tailed skate is primarily solitary, although it may sometimes be observed in small groups, especially during the breeding season. It is not particularly territorial and moves slowly along the bottom in search of food. It is relatively insensitive to changes in pressure and light but avoids overly turbulent waters. Its behavior is influenced by food availability and water temperature.

The diet of the short-tailed skate mainly consists of small crustaceans, mollusks, and bottom fish. Young skates primarily feed on small prey that are easy to catch, while adults have a more varied diet. In winter, their metabolism slows down, and they may reduce their feeding activity, relying on what is readily available.

In spring, the short-tailed skate begins to move to areas more conducive to breeding. Summer is a period of increased activity, during which it is more likely to be accidentally caught by fishermen. In fall, it starts migrating to deeper waters, following the drop in temperatures. In winter, it retreats to deep habitats, where it remains relatively inactive. The best chances of capture occur during the warm months, early in the morning or late in the afternoon, when weather conditions are stable.

For the short-tailed skate, lures are generally not effective. Instead, prefer natural baits like squid or shrimp. If you use lures, choose natural colors and slow movements to mimic the skate's usual prey.

To fish for the short-tailed skate, use a sturdy rod about 2.4 meters long with heavy power. A spinning reel is ideal for prolonged battles. Opt for a line of 30 to 50 lb, and circle hooks sized 4/0 to 6/0. A steel leader may be useful to prevent the skate from cutting the line with its teeth.

When you catch a short-tailed skate, handle it carefully to avoid damaging it. Use a damp cloth to grasp it and support its body well. If you release it back into the water, make sure it is well-oxygenated before letting it go. Avoid keeping it out of the water for too long to prevent stressing it.

The main predators of the short-tailed skate include some large fish like the Greenland shark and seabirds like the gannet that may prey on young skates.

The short-tailed skate is currently considered a species of minor concern in Canada, but climate change and bycatch can affect its populations. Regulations vary, but catch and release is often encouraged to maintain healthy populations.
