The round skate, or Rajella fyllae, is a species of skate found in the salt and brackish waters of Quebec, although it is more common in the colder waters of the North Atlantic. Although it is not a primary target for sport fishing due to its low fighting ability, it still generates some interest among anglers curious to discover the diversity of marine species. Its presence in Quebec waters is rarer than that of some other skates, but it can occasionally be observed by bottom fishermen exploring the deeper areas of the Gulf of St. Lawrence.

The round skate is distinguished by its flattened, disc-shaped body, with wide pectoral fins giving it an almost circular appearance. Its color varies from brown to gray, sometimes with darker spots that can help camouflage it on the seabed. Its mouth is located on the ventral side, typical of skates, with small teeth adapted for crushing crustaceans and mollusks. Young round skates are often lighter than adults, while males and females do not show significant differences outside of the breeding season, when males develop claspers, specialized structures for reproduction.

In Quebec, the round skate is primarily found in the cold waters of the Gulf of St. Lawrence and the Strait of Belle Isle. It is mostly found in deeper areas, often beyond 100 meters, where the water temperature is more stable and cold. It is less abundant in coastal waters and is rarely observed in estuaries, making it less accessible for amateur anglers. Its distribution is relatively limited compared to other species of skates, making it an occasional and often accidental catch during deep-sea fishing outings.

The round skate prefers deep, cold waters, generally between 100 and 1000 meters deep. It favors sandy or muddy seabeds, where it can camouflage itself to hunt for prey. The ideal temperature of its habitat is around 4 to 10 °C, making it more common in the northern regions of the Gulf of St. Lawrence. Anglers will rarely find it near the coast, as it generally avoids warmer, shallower waters. The round skate is often observed near natural underwater structures, such as canyons and continental shelves, where it can rest and feed.

The round skate reproduces by laying eggs encapsulated in horny capsules, often called "mermaid's purses." These capsules are deposited on the seabed, where they hatch after several months, releasing fully formed young skates. The growth of young skates is relatively slow, and they reach sexual maturity between 3 and 5 years. Their longevity can reach up to 12 years under optimal conditions. In spring, skates begin their breeding period, while in summer, they focus on feeding to accumulate reserves. Autumn sees a decrease in reproductive activity, and in winter, they retreat to deeper waters to avoid temperature fluctuations.

The round skate is generally a solitary species, although it can be observed in small groups when feeding. It is not particularly territorial and tolerates the presence of other skates in its immediate environment. It reacts little to noise and external disturbances, making it less sensitive to sudden environmental changes, such as wind or light variations. However, it is more active at night, taking advantage of the darkness to hunt for prey. In case of danger, it uses its natural camouflage to blend into the seabed.

The diet of the round skate primarily consists of crustaceans, mollusks, and small benthic fish. Young skates mainly feed on small invertebrates, while adults prefer larger prey that can provide more energy. In summer, when food resources are more abundant, it increases its feeding activity, while in winter, it reduces its metabolism and feeds less frequently. This dietary flexibility allows it to survive in environments where resources may be limited.

In spring, the round skate begins to move to areas more conducive to reproduction, taking advantage of the milder temperatures. In summer, it is more active and focuses on feeding, often easier to catch due to the abundance of prey. Autumn marks a transition period when it starts to retreat to deeper waters to escape the drop in temperature. In winter, its activity decreases significantly, and it rests in deep areas where conditions are more stable. The best times to observe it are often at night or early in the morning, when hunting activity is at its peak.

For the round skate, natural baits are often more effective than artificial lures. However, if you want to use lures, choose colors that mimic the seabed, such as brown or green, especially in clear waters. In murky waters, brighter colors like yellow can help attract the skate's attention.

To fish for the round skate, a sturdy fishing rod about 2.4 to 3 meters long is recommended, with a medium to heavy power to withstand the weight and strength of the fish. A robust reel with a large line capacity is essential. Use a line of 20 to 30 lb to manage depths and currents. The hooks should be strong and large enough to hold natural baits.

Handling the round skate should be done with care to avoid stressing the animal. Use gloves to protect your hands and support the skate from underneath to avoid injuring it. If you wish to release it back into the water, ensure it is well-oxygenated before letting it go. For photos, be quick and keep the animal close to the water.

The main predators of the round skate include large sharks and certain species of seals. Seabirds can also pose a threat to young skates when they are near the surface.

The round skate is not considered an endangered species in Quebec, but its fishing is generally regulated to avoid accidental overfishing. Anglers are encouraged to practice catch and release for specimens caught accidentally, thus contributing to the conservation of the species.
