The Arctic stichaeus, although not well known to sport fishermen, is a fascinating species from the cold waters of Quebec. It is not highly valued for recreational fishing due to its low fighting ability, but it remains interesting for ichthyologists and marine biodiversity enthusiasts. It is primarily found in the salt and brackish waters of the Gulf of St. Lawrence and Hudson Bay. The Arctic stichaeus plays an important role in the marine ecosystem, serving as prey for many aquatic and avian predators. Its presence is an indicator of the health of northern marine ecosystems.

The Arctic stichaeus has an elongated and slightly compressed body, typically measuring between 15 and 25 cm. Its color ranges from brownish to greenish, with irregular dark spots on the back and sides, allowing it to effectively camouflage in rocky seabeds. The head is relatively small with an underslung mouth and thick lips. The pectoral fins are large and rounded, while the dorsal and anal fins are long and low, extending almost the entire length of the body. The tail is slightly forked. Young stichaeus exhibit brighter colors and more pronounced patterns than adults. There is no pronounced sexual dimorphism, even during the spawning period.

In Quebec, the Arctic stichaeus is mainly found in the Gulf of St. Lawrence, Hudson Bay, and the coastal waters of the Lower North Shore. It is rare in fresher waters and absent from more southern regions, such as the St. Lawrence River beyond Quebec. This species prefers cold, nutrient-rich waters typical of northern areas. Although it is less abundant than other bottom fish species, it plays an important ecological role in these environments.

The Arctic stichaeus frequents shallow coastal waters, often at depths of 5 to 100 meters. It prefers rocky or sandy bottoms, where it can easily camouflage. The ideal temperatures for this species range from 2 to 8 °C, which explains its preference for the cold waters of northern Quebec. It is often encountered near underwater structures such as reefs and rock piles, where it can find shelter and food.

The spawning of the Arctic stichaeus occurs in spring when water temperatures begin to warm slightly. Females lay their eggs on rocky substrates, where they adhere until hatching. The larvae hatch after a few weeks and drift in the plankton before developing into juveniles and joining the seabed. Sexual maturity is reached between 1 and 2 years, and the species' longevity is generally 4 to 6 years. Spring → Spawning → Summer → Juvenile growth → Autumn → Winter preparation → Winter → Partial hibernation.

The Arctic stichaeus is generally a solitary fish, although it may be found in small groups when feeding. It is not particularly territorial, but it may show aggression if disturbed in its habitat. Sensitive to sudden changes in light and noise, it prefers calm and undisturbed environments. In the face of danger, it camouflages itself in rocky bottoms rather than fleeing.

The diet of the Arctic stichaeus varies with age. Larvae and juveniles primarily feed on zooplankton and small invertebrates. As they grow, adult stichaeus consume crustaceans, mollusks, and small fish. Their diet is influenced by prey availability and may vary by season, with more intense feeding activity during the summer months.

The Arctic stichaeus is active year-round, but it is easier to observe and catch during the warmer months, from spring to autumn. During these seasons, it feeds more intensively, especially at dawn and dusk. In winter, it reduces its activity, staying deeper in the water to avoid freezing surface temperatures. The best conditions for fishing are overcast days with stable atmospheric pressure, as it is less sensitive to light variations.

For the Arctic stichaeus, opt for natural-colored lures, such as brown or green, which closely mimic its environment. In clear water, silver or white lures can attract its attention. In murky water, prefer brighter colors like yellow or orange to increase visibility. Shallow lures are usually sufficient, but during summer, don't hesitate to go deeper with diving lures.

For the Arctic stichaeus, a rod of 1.8 to 2.1 m with light to medium power and fast action is ideal. A light casting reel with a line of 6 to 10 lb is generally sufficient. Use hooks size 6 to 8 for natural baits. A fluorocarbon leader can be useful for its discretion in clear water.

Handle the Arctic stichaeus carefully to avoid causing it stress. Use wet hands or a damp cloth to avoid removing the protective mucus from its skin. If you wish to release it back into the water, do so quickly after capture. For a photo, hold it close to the water and ensure it is well supported to avoid injury.

The main predators of the Arctic stichaeus include larger fish such as halibut and cod, as well as seabirds like cormorants. Seals may also feed on it, especially in more northern regions.

The Arctic stichaeus is not currently considered a threatened species in Quebec. However, it is sensitive to environmental changes, such as pollution and habitat loss. Local regulations may require the release of certain catches to ensure the sustainability of populations.
