Rainbow trout are beautiful. They are found throughout North America, but they are native to the coastal waters and tributary streams of the Pacific basin. Currently, there are over a dozen rainbow trout subspecies in the world. Some rainbow trout live only in freshwater lakes and rivers, while others migrate between freshwater to spawn and the ocean. These shimmering fish grow large, but just how big do they get? What about in Arizona? Follow along to discover the largest rainbow trout ever caught in Arizona.

About the Rainbow Trout

In 1792 Johann Julius Walbaum named the species rainbow trout. Its scientific name is Oncorhynchus mykiss. There are also multiple subspecies, including coastal forms, redband forms, Mexican forms, mutated forms, and Kern River golden trout. These beautiful shimmering fish vary in size and appearance.

Description and Size

Most rainbow trout measure between 20 to 30 inches. Some subspecies, like the Kern River rainbow trout, are larger than other species. These region-specific trout grow up to 28 inches long. One of the smallest subspecies is the Little Kern golden trout, which barely grows past 10 inches. A Little Kern golden trout larger than 10 inches long, is considered a large catch. Freshwater rainbow trout typically weigh between 1 to 5 pounds. Another popular rainbow trout subspecies for anglers is the Eagle Lake rainbow trout. On average, it weighs 2 pounds.

Rainbow trout have blue-green or olive-green skin with spots throughout their bodies. However, some subspecies are lighter, while others are darker. Most adult rainbow trout also have a broad reddish stripe along the lateral line. This line runs from their gills to their tails. Lake-dwelling rainbow trout fish are typically more silvery. This coloring helps them blend in and hide from predators. Other subspecies have pink or reddish markings, like the cutthroat trout, with silver. One of the most unique rainbow trout subspecies is the golden trout. They are native to California and are easy to spot. Golden trout have golden flanks with bright red horizontal bands and about 10 dark oval marks on each side. Golden trout fish are beautiful, vibrant, and small, rarely growing past 10 inches long.

Rainbow trout are carnivorous predators, but they aren’t overtly aggressive. They have a varied diet and aren’t picky. Most rainbow trout consume aquatic insects like larval, pupal, mayflies, stoneflies, and caddisflies. Rainbow trout also eat land insects like ants if they fall into the water. Other than insects, rainbow trout fish eat algae, fish eggs, small fish, snake hatchlings, and crustaceans. Adult coastal rainbow trout eat squids, fish, and amphipods.
