Rainbow Trout

At FML, we specialize in stocking Rainbow Trout that are prized for their vibrant colors, athletic fighting spirit, and remarkable adaptability. When FML stocks these high-performance fish, we provide a dynamic experience for anglers of all skill levels; they are famously surface-active, frequently rising to flies and jumping when hooked. As one of the hardiest species available, our FML-sourced Rainbows are capable of thriving in a wide range of water conditions—from high-altitude mountain streams to managed Great Plains ponds. Because of their widespread availability and natural resilience, Rainbows are an affordable and budget-friendly species to stock, allowing property owners to establish a high-quality, high-action fishery that remains well within a sustainable management budget.

Native to the cold-water tributaries of the Pacific Rim in North America and Asia, the Rainbow Trout (Oncorhynchus mykiss) is a highly adaptable salmonid that exists in both landlocked and migratory (Steelhead) forms. Though first described by naturalists in 1792, its global history changed forever in the 1870s when the first successful captive spawning occurred at California’s McCloud River. These hardy "McCloud rainbows" proved so resilient that they were soon transported via rail and steamship to every continent except Antarctica. Today, following a 1989 genetic reclassification that moved them from the Salmo (Atlantic) genus to Oncorhynchus (Pacific), they remain the most widely introduced and economically significant game fish in the world.
