The snake blenny, although not well known to sport fishermen, is a fascinating fish from Quebec. It is primarily found in the salty and brackish waters of the estuary and Gulf of St. Lawrence. This elongated fish, resembling an eel, is more often caught accidentally than actively targeted. Its low fighting ability makes it a less popular choice for sport fishing, but it can present an interesting challenge for those looking to diversify their catch. Its distribution is mainly limited to cold, shallow waters where it feeds on small invertebrates.

The snake blenny has an elongated, serpentine body, reminiscent of an eel. Its color ranges from yellowish-brown to olive brown, with lighter patterns on the flanks. The head is small with a terminal mouth, and the eyes are relatively large. The dorsal and anal fins are long and continuous, almost merging with the caudal fin. The scales are small, giving it a smooth appearance. Young individuals are often lighter than adults, and the differences between males and females are not pronounced, even during spawning.

The snake blenny is mainly observed in the cold waters of the estuary and Gulf of St. Lawrence. It is more frequent in shallow coastal areas, often near sandy or muddy bottoms. Its presence is limited to regions where salinity is moderate, which excludes the freshwater waters of rivers and inland lakes in Quebec. Although it is abundant in its preferred habitat, its natural discretion often makes it unnoticed.

The snake blenny prefers salty and brackish waters, generally shallow, up to about 50 meters deep. It is often found on sandy or muddy bottoms where it can camouflage itself. It is well adapted to cold waters, with an ideal temperature between 4 and 10 °C. Fishermen can look for it near underwater structures like kelp or rocks where it finds its food. Due to its discreet nature, it is more active near the bottom.

The reproduction of the snake blenny occurs in the spring, when temperatures begin to rise slightly. Females lay their eggs on solid substrates where they adhere until hatching. The eggs hatch after a few weeks, releasing larvae that feed on plankton before growing and settling to the bottom. Sexual maturity is reached between one and two years, and the longevity of this species is relatively short, ranging from four to six years.

The snake blenny is rather solitary and non-territorial. It spends most of its time near the bottom, where it feeds and hides from predators. It is not very sensitive to changes in pressure and reacts moderately to noise and movement in the water. Weather conditions do not drastically affect its behavior, although it may be more active on cloudy days or during calm seas.

The diet of the snake blenny consists mainly of small benthic invertebrates. Young individuals feed on zooplankton and small crustaceans. As they grow, their diet expands to include worms, mollusks, and small crustaceans. Their diet varies little with the seasons, although they may take advantage of the abundance of certain prey at specific times of the year.

Fishing for the snake blenny is possible year-round, although it is more active in spring and summer when water temperatures are more favorable. It is often caught accidentally while fishing for other species. The best times to catch it are early in the morning or late in the afternoon, especially on cloudy days. Calm sea conditions and days when atmospheric pressure is stable may also promote its activity.

To fish for the snake blenny, lures are generally not necessary, but if you choose to use them, opt for natural colors like brown or olive that mimic natural prey. In clear waters, light colors are effective, while in murky waters, darker shades may attract more attention.

To fish for the snake blenny, a light rod with a moderate action of about 6 to 7 feet is ideal. Use a small to medium-sized reel with a line of 6 to 10 lb. Size 6 to 10 hooks are appropriate, and a fluorocarbon leader can be useful for discretion in the water.

Handle the snake blenny carefully, avoiding holding it by the gills. For release, ensure it is well oxygenated before letting it go. A quick photo is possible, but minimize the time out of the water.

Natural predators of the snake blenny include larger fish like halibut and seabirds such as cormorants that patrol the coasts.

The snake blenny is not currently endangered in Quebec. Its population is stable, but it is rarely targeted by sport fishing. No specific regulations apply to this species, but catch and release is encouraged to maintain ecological balance.
