That said, there is a considerable consensus that all three major trout species (brook, brown and rainbow) begin to experience some level of stress at around 68Â°F (20Â°C), with that stress increasing rapidly as the temperature rises further.
The Golden Rainbow Trout is a different species than the Golden Trout (Oncorhynchus aguabonita) of some California streams. In fish hatcheries, the Rainbow Trout has occasionally produced other unusual genetic mutations, such as the Blue Rainbow Trout, whose body color is sky-blue.he Golden Rainbow Trout is a different species than the Golden Trout (Oncorhynchus aguabonita) of some California streams.
