The straw-colored minnow, or Notropis stramineus, is a small freshwater fish commonly found in Quebec. Although it is not targeted for sport fishing due to its modest size, it plays an essential role in aquatic ecosystems as prey for various predators. It is primarily found in clear, shallow waters of rivers and lakes. Its presence is often a good indicator of the health of the aquatic ecosystem. For anglers, it serves as excellent bait to attract larger fish such as walleye or pike. Its distribution extends throughout southern Quebec, particularly in the watersheds of the Saint Lawrence and Outaouais rivers.

The straw-colored minnow is an elongated and fusiform fish, usually measuring between 2 and 3 inches in length. Its body is covered in silver scales with a slightly golden hue, which gives it its name. The lateral line is well-defined and visible. Its mouth is small and terminal, suited to its diet of invertebrates and small aquatic insects. The dorsal and anal fins are relatively small and transparent, while its caudal fin is forked. There are few differences between males and females, although males may display brighter colors during spawning. Young fish are similar to adults but have more translucent scales.

The straw-colored minnow is widely distributed in southern Quebec, where it frequents rivers and lakes with moderate currents. It is primarily found in the watersheds of the Saint Lawrence, Outaouais rivers, and in certain sections of the Richelieu and Yamaska rivers. Although abundant in these regions, it is less common in the colder waters of northern Quebec. Its presence is often correlated with clear, well-oxygenated waters, making it a good indicator of water quality.

The straw-colored minnow prefers clear, shallow waterways with sandy or gravelly bottoms. It is often found in rivers with moderate currents and shallow lakes, where it can hide among aquatic plants and submerged structures. It tolerates some turbidity but is generally absent from very murky or stagnant waters. Areas with dense aquatic vegetation provide both protection from predators and an abundance of food.

The spawning of the straw-colored minnow occurs in spring, usually when the water temperature reaches about 59 °F. Females lay adhesive eggs on gravel and sandy bottoms, often near aquatic plants. The eggs hatch after a few days, and the fry quickly begin to feed on zooplankton. Growth is rapid, and young fish reach sexual maturity in one to two years. The lifespan of the straw-colored minnow is relatively short, often limited to two or three years.

The straw-colored minnow is a schooling fish, often living in compact schools that move together to feed and protect themselves from predators. Non-territorial, it is rarely aggressive towards other fish. It is sensitive to changes in light and temperature, which influence its feeding habits and movements. Schools are less dispersed during overcast or windy weather, preferring calmer, sheltered waters.

The diet of the straw-colored minnow varies slightly with age. Fry primarily feed on zooplankton, while adults consume a wider variety of aquatic invertebrates, such as insect larvae, small crustaceans, and algae. In summer, their diet becomes more diverse due to the abundance of food. In winter, they feed less frequently and focus on available prey.

In spring, the straw-colored minnow is more active, actively seeking food after the spawning period. In summer, it is often seen near the surface, especially early in the morning and late in the afternoon when light is less intense. In fall, its activity gradually decreases with falling temperatures. Winter is a period of low activity, and minnows group together in deeper, sheltered waters to conserve energy. Weather conditions such as wind and atmospheric pressure have little influence on their behavior, although they prefer calm, sunny days.

For the straw-colored minnow, the use of lures is not common due to its size and ecological role. However, if you wish to experiment, prefer small silver or golden lures that mimic their natural shimmer. In clear waters, natural colors are preferred, while in murkier waters, brighter colors can be used to attract attention.

An ultralight rod of 5 to 6.5 feet is ideal for targeting the straw-colored minnow, especially if you want to use it as bait. The reel should be light, with a line of 2 to 4 lb to minimize visibility. Hooks size 16 to 20 are appropriate to avoid injuring the fish. No need for a heavy leader, a simple fluorocarbon line will do.

Although the straw-colored minnow is often used as bait, if you wish to release it, handle it as little as possible to avoid damaging its protective mucus. Use wet hands to gently unhook it and ensure it recovers before returning it to the water. For a photo, be quick and avoid taking it out of the water for too long.

The straw-colored minnow is a preferred prey for many predatory fish in Quebec, such as pike, walleye, and bass. It is also hunted by aquatic birds such as herons and kingfishers, who take advantage of its surface swimming to catch it.

The straw-colored minnow is not considered a threatened species in Quebec. Its population is stable, and there are no specific regulations regarding its capture. However, preserving its natural habitat is essential to maintain its populations, as it is an indicator of water quality.
