Golden Trout

The golden trout (Oncorhynchus aguabonita), is a species of freshwater fish in the salmon family (family Salmonidae) of order Salmoniformes. It is one of the trouts. These fish are commonly found at elevations of 10,000 feet (3,000 m) above sea level. Some evolutionary biologists consider the golden trout to be a subspecies of the rainbow trout, Oncorhynchus mykiss.  It is easy to understand, given the similarity of the golden trout to the redband trout, Oncorhynchus mykiss ssp.

The golden trout has brilliant gold sides wih a red horizontal band and 10 dark oval marks called "parr marks" their fins have white edges. A typical adult will be up to 14 inches in length and averages 1 pound in streams, up to 11 pounds in weight in lakes, according to the world record fish caught by Charles S. Reed, on August 5, 1948, from Cook Lakes in the Wind River Range. Preferred water temperature is between 58 and 62 Degrees Fahrenheit. The brilliant colors of the Golden Trout disappear if they are stocked at altitudes lower than 6,000 feet. Contrary to common belief that golden trout parr marks persist throughout their adult life, golden trout lose parr marks at 17 inches.

Golden trout inhabit high altitude lakes due to their inability to compete with the other trout species. Once brook trout are introduced into golden trout water the golden trout populace will decline rapidly. The introduction of rainbow and or cutthroat creates hybridization as they both spawn in the spring.

The golden trout was designated as the state fish of California in 1947. Populations have been in steady decline for decades. As a result, the California department of fish and game signed an agreement with federal agencies in September 2004 to work on restoring back country habitat. Conservationists have also been attempting to introduce golden trout to other bodies of water, such as Mohave Lake in Nevada/Arizona.
