Walleye vs Pickerel: Difference and Comparison

Walleye and pickerel are confused due to similar appearances, but they belong to different families. Walleye, scientifically known as Sander vitreus, are prized game fish known for their large size and excellent taste, primarily found in freshwater habitats across North America. Pickerel, on the other hand, refer to several species within the Esox genus, such as the chain pickerel and the grass pickerel, known for their aggressive feeding habits and inhabiting similar freshwater ecosystems.

Key Takeaways

1. Walleye and pickerel are freshwater fish with similar appearance and taste.
2. Walleye have larger eyes and are more likely to be found in deeper, colder waters, while pickerel are found in warmer, shallower waters.
3. “pickerel” is used interchangeably with “northern pike”, a different fish species.

Walleye vs Pickerel

Walleye is a freshwater fish native to North America, known for its delicious taste and large, sharp teeth. Pickerel is a species of fish in the pike family and ability to catch prey quickly. They are found in slow-moving bodies of water and have a dark green or olive colour, with a lighter belly and small, sharp teeth.

Walleye is a freshwater perciform fish found mostly in Canada and the Northern United States. They belong to the pike family and are olive or gold in colour.

Pickerels, on the other hand, are freshwater fishes, more precisely known as Chain Pickerels. They, too, are found in Canada and the Northern United States. They have a rather greenish colour, mostly on their sides.

What is Walleye?

Walleye, scientifically known as Sander vitreus, is a species of freshwater fish native to North America. It belongs to the Percidae family, which also includes yellow perch and sauger. Renowned among anglers for its sport fishing qualities and delectable flesh, the walleye is a prized catch in various freshwater bodies across the continent.

Physical Characteristics

1. Appearance: Walleye are characterized by their sleek, elongated bodies with olive-green or brownish backs and brassy or golden sides. They have distinctive marble-like patterns along their flanks and a white belly. One of the most notable features is their large, glassy eyes, which appear to “glow” in low light conditions, giving them their name.
2. Size: These fish range in size from 12 to 30 inches, although specimens exceeding 30 inches are not uncommon, especially in nutrient-rich waters. The weight of walleye varies greatly depending on their habitat and available food sources, with trophy specimens weighing over 10 pounds.

Natural Habitat and Distribution

1. Habitat: Walleye thrive in a variety of freshwater environments, including large lakes, reservoirs, rivers, and some smaller inland lakes. They prefer cool, clean waters with moderate vegetation and ample prey species. Walleye inhabit deeper areas during the day and move to shallower waters at dawn and dusk to feed.
2. Distribution: Native to North America, walleye are found throughout much of the continent, from the northern reaches of Canada to the central and eastern United States. They are particularly abundant in the Great Lakes region and the Mississippi River basin. Due to their popularity as game fish, walleye have been introduced to many other regions where they were not originally found.

Feeding Behavior

1. Nocturnal Predators: Walleye are primarily nocturnal feeders, relying on their exceptional low-light vision to hunt effectively during dawn, dusk, and nighttime hours. Their large eyes, equipped with a layer of reflective cells called tapetum lucidum, enhance their ability to see in dim conditions.
2. Prey Species: Walleye have diverse diets, feeding on a variety of aquatic organisms such as minnows, crayfish, insects, and smaller fish species. They are opportunistic predators, targeting whatever prey is most abundant and easily accessible in their habitat.

Importance to Anglers and Conservation

1. Sport Fishing: Walleye are highly prized by anglers for their challenging fights and delicious flesh. Their popularity as a game fish has led to extensive management efforts to sustain healthy walleye populations in many freshwater ecosystems. Fishing for walleye can be both recreational and commercial, contributing significantly to local economies in regions where they are abundant.
2. Conservation Concerns: Despite their widespread distribution, walleye populations face threats from habitat degradation, pollution, overfishing, and competition with invasive species. Conservation measures such as habitat restoration, stocking programs, and catch limits are crucial for ensuring the long-term sustainability of walleye fisheries.

What is Pickerel?

“Pickerel” is a common name used to refer to several species of freshwater fish belonging to the Esox genus, which also includes pike and muskellunge. These fish are known for their predatory behavior and are prized by anglers for their aggressive strikes and fighting ability. While confused with walleye due to similar appearances, pickerel species have distinct characteristics and habitats.

Common Species

1. Chain Pickerel (Esox niger): Found primarily in the eastern United States, chain pickerel inhabit slow-moving waters such as swamps, ponds, and backwaters of streams. They are characterized by a chain-like pattern along their greenish backs and sides, with a lighter belly. Chain pickerel grow to lengths of 18 to 24 inches, although larger specimens are possible.
2. Redfin Pickerel (Esox americanus americanus): Native to the southeastern United States, redfin pickerel prefer shallow, vegetated areas of streams, swamps, and ponds. They have distinctive red markings on their fins, which contrast with their olive-green bodies. Redfin pickerel are smaller than chain pickerel, averaging around 8 to 12 inches in length.

Physical Characteristics

1. Appearance: Pickerel species have elongated, torpedo-shaped bodies with elongated snouts filled with sharp teeth. They exhibit various shades of green, brown, or olive along their backs, adorned with patterns such as spots, bars, or stripes. Their bellies are lighter in color.
2. Size: Pickerel species vary in size depending on the specific species and environmental conditions. Chain pickerel, for example, can reach lengths of up to 30 inches, while redfin pickerel are smaller, averaging around 8 to 12 inches in length. Larger specimens of pickerel can offer exciting angling opportunities for fishermen.

Natural Habitat and Distribution

1. Habitat: Pickerel species are found in freshwater habitats with ample vegetation and cover, including ponds, lakes, slow-moving streams, and backwaters. They prefer areas with submerged vegetation or woody debris where they can ambush their prey. Pickerel are associated with areas of dense aquatic vegetation.
2. Distribution: While pickerel species have specific regional distributions, they are primarily found in North America. Chain pickerel are more common in the eastern United States, particularly along the Atlantic coastal plain, while redfin pickerel are native to the southeastern United States. Some pickerel species have been introduced to other regions where they have become established.

Feeding Behavior

1. Aggressive Predators: Pickerel are voracious predators, feeding on a variety of aquatic prey species, including fish, amphibians, insects, and small crustaceans. They rely on stealth and ambush tactics to capture their prey, hiding among vegetation or other cover before striking with lightning speed.
2. Feeding Habits: Pickerel are opportunistic feeders, preying on whatever species are abundant and easily accessible in their habitat. They are particularly aggressive towards smaller fish, using their sharp teeth to grasp and subdue their prey. Pickerel are most active during daylight hours, especially in the early morning and late afternoon.

Importance to Anglers and Conservation

1. Sport Fishing: Pickerel are popular among anglers for their aggressive strikes and challenging fights. They are targeted using a variety of fishing techniques, including casting lures, trolling, and fly fishing. Pickerel fisheries contribute to recreational angling opportunities in many freshwater ecosystems.
2. Conservation Concerns: While not as heavily managed as some other game fish species, pickerel populations can be susceptible to overfishing and habitat degradation. Conservation efforts aimed at preserving and restoring freshwater habitats benefit pickerel populations and the overall health of aquatic ecosystems. Implementing sustainable fishing practices and habitat conservation measures are essential for maintaining healthy pickerel populations for future generations of anglers.
