Ontario waters are home to dozens of fish species, from mighty muskellunge to delicate sunfish. But if you're new to fishing or looking for a reliable, delicious catch, rainbow trout stands out as a favorite. What makes rainbow trout special compared to other Ontario fish? Let's dive into the differences and discover why so many anglers—especially beginners and families—choose to target these beautiful fish.
Meet the Rainbow Trout
Rainbow trout (Oncorhynchus mykiss) are named for the distinctive pink or red stripe running along their sides, which shimmers like a rainbow when they're pulled from the water. Originally native to the Pacific coast, they were introduced to Ontario waters over a century ago and have thrived in our cold, clean lakes and streams.
In Ontario, you'll find rainbow trout in two main environments: Wild populations in streams and lakes, particularly in Northern Ontario and the Great Lakes tributaries. Stocked populations in lakes, ponds, and private trout farms like Thistle Springs. They typically range from 10 to 16 inches in stocked waters, though wild fish in large bodies of water can grow much larger.
Rainbow Trout vs. Other Trout Species
Ontario has several trout species. Here's how rainbow trout compare to their cousins.
Brook Trout: Ontario's only native trout. Smaller than rainbows, typically 6-12 inches. Prefer colder water. More challenging to catch in wild settings. Beautiful coloring with red spots.
Lake Trout: Much larger, can exceed 20 pounds. Found in deep, cold lakes. Require boats and specialized equipment for most anglers.
Brown Trout: Can grow larger than rainbows. More wary and difficult to catch. Excellent fighters. Less common in stocked ponds.
Why Choose Rainbow Trout?
They're the most adaptable and beginner-friendly trout. They tolerate warmer water better than brook or lake trout. They're aggressive feeders, so they bite readily. They're commonly stocked, making them accessible near urban areas. They fight well when hooked, making them exciting to catch.
Rainbow Trout vs. Bass
Largemouth and smallmouth bass are Ontario's most popular sport fish. How do they compare to rainbow trout?
Size: Bass average 12-18 inches, similar to stocked rainbow trout. Wild bass can grow larger.
Habitat: Bass prefer warmer water and weed beds. Trout need cold, oxygenated water.
Fighting Ability:Bass are known for jumping and aggressive runs. Trout fight hard but differently—more sustained pulling.
Ease of Catching: Stocked trout are easier for beginners. Bass require more skill and knowledge.
Eating Quality: Both are excellent, but trout has a milder, more delicate flavor.
Season: Bass have closed seasons in spring during spawning. Trout farms like Thistle Springs operate year-round (weather permitting). Best For Beginners? Rainbow trout, especially in stocked environments.
Rainbow Trout vs. Pike and Muskellunge
Northern pike and muskellunge are apex predators—toothy, aggressive fish that grow large and fight hard.
Size: Pike and muskie can exceed 30-40 inches. Much larger than rainbow trout.
Teeth: These fish have sharp teeth requiring steel leaders. Trout have no teeth, making them safer to handle.
Difficulty: Pike and muskie require specific techniques and equipment. Trout are much more beginner-friendly. Eating
Quality: Trout wins hands-down. Pike and muskie are bony and less desirable to eat.
Accessibility: Trout are far more accessible in stocked ponds and urban waters.
Verdict: If you want an easy, delicious catch, trout is the clear winner.
Rainbow Trout vs. Panfish (Perch, Sunfish, Crappie)
Panfish are small, abundant, and fun to catch. How do they stack up against rainbow trout?
Size: Panfish are typically 4-8 inches. Trout are larger and more substantial. Eating
Quality: Both are delicious, but you need many panfish for a meal. One or two trout provide a full serving.
Fighting Ability: Panfish offer minimal fight. Trout pull harder and are more exciting.
Accessibility: Both are beginner-friendly. Panfish are everywhere; trout require colder water or stocked ponds. For a
Satisfying Catch: Rainbow trout offer a better overall experience—bigger fish, better fight, easier meal preparation.
