The longnose gar, also known as garpike, is a fascinating and ancient fish that inhabits the freshwater waters of Quebec. Although it is not the first choice of sport fishermen due to its moderate fighting ability, it attracts interest with its prehistoric appearance and unique behavior. It is primarily found in the calm, warm waters of rivers and lakes in southern Quebec. Its distribution includes the watersheds of the Saint Lawrence River, where it often mingles with other fish species. As an opportunistic predator, the longnose gar plays an important ecological role by regulating the populations of small fish and aquatic invertebrates.

The longnose gar is distinguished by its elongated, cylindrical body covered with large ganoid scales, which provide remarkable protection. Its color varies from olive brown to dark green on the back, with lighter sides often marked with dark spots. The mouth is long and narrow, equipped with many small sharp teeth, ideal for catching its prey. The fins, relatively small, are positioned toward the back of the body, and the caudal fin is slightly forked. Young gars display more pronounced patterns, while adults may appear duller. During the spawning season, males become more colorful than females, with brighter hues on the fins.

In Quebec, the longnose gar is primarily found in the southern regions, particularly in the watersheds of the Saint Lawrence River. It is also found in certain rivers and lakes in Montérégie, Estrie, and Outaouais. It prefers calm waters, such as shallow bays and backwaters of rivers. Although it is less common in more northern areas, it can sometimes be observed in favorable habitats. Its distribution is influenced by the availability of spawning areas and abundant prey populations.

The longnose gar prefers calm, warm waters, often found in lakes, slow-moving rivers, and marshy areas. It is generally observed near the shores, where aquatic vegetation is abundant, providing both shelter and ideal hunting grounds. Submerged structures, such as fallen trees and rocks, are also places where it likes to hide. It tolerates a wide range of temperatures but is more active in moderately warm waters, around 68 to 82 °F.

The spawning period of the longnose gar occurs in spring when water temperatures reach about 68 °F. Females deposit their adhesive eggs among aquatic vegetation, where they hatch after about a week. The larvae feed on zooplankton before transitioning to a more piscivorous diet as they grow. Sexual maturity is reached between 3 and 4 years, and the species can live up to 12 years. Spring → Spawning → Summer → Rapid growth → Fall → Winter preparation → Winter → Slowed metabolism.

The longnose gar is generally a solitary fish, although it may be observed in small groups during the spawning period. It is not particularly territorial but defends its hunting space against intruders. Sensitive to changes in light, it prefers low-light conditions for hunting. Sudden movements and noise can scare it away, but it is less affected by changes in atmospheric pressure.

The longnose gar is an opportunistic predator whose diet evolves with age. Young gars primarily feed on zooplankton and aquatic insects. As they grow, they switch to a diet consisting of small fish, amphibians, and crustaceans. In winter, its feeding activity decreases, but it continues to hunt opportunistically when the opportunity arises.

In spring, as temperatures rise, the longnose gar becomes more active, especially at dawn and dusk. In summer, it is easier to spot in shallow, warm waters. Cloudy, calm days are ideal for fishing. In autumn, its activity decreases as temperatures drop, but it remains active during sunny periods. In winter, it retreats to deeper waters and slows its metabolism, making it harder to catch.

For clear waters, use lures in natural colors like green and brown, which mimic local prey. In murky water, bright colors like yellow or orange can increase visibility. Sunny days require less bright lures to avoid glare, while overcast weather can benefit from more vibrant colors to attract attention.

A 6 to 7-foot rod with medium power and fast action is ideal for longnose gar. Use a reel sized 3000 to 4000 with a 10 to 15 lb line. Treble hooks size 4 to 6 are recommended, and a steel leader can prevent cuts from sharp teeth.

Handle the longnose gar with care to avoid its sharp teeth. Use gloves and a dehooking tool to remove the hook. For release, support the fish by the belly until it recovers enough to swim away on its own. Take photos quickly to minimize stress.

Adult longnose gar have few natural predators due to their size and protective scales. However, young gars can fall prey to piscivorous birds like herons and ospreys, as well as large predatory fish.

The longnose gar is not considered a threatened species in Quebec, but it is important to respect current fishing regulations regarding size and bag limits. Catch and release is encouraged to preserve local populations and maintain ecological balance.
