Description
Appearance
- Golden trout are the most colourful of trout, with an olive-green back and bright red-to-gold sides and belly.
- In the spring spawning season, the colours are extremely intense.
Distribution
- Golden trout are native only to a few small lakes and streams at high elevations in the Sierra Nevada of California.
- In 1959, they were introduced into a few lakes in the mountains of southwestern Alberta.
Natural History
Habitat
- Golden trout are very specialized for their high mountain lake environment, and do not do well in lower-elevation streams and lakes.
Reproduction and Growth
Breeding Behaviour
- Spawning takes place from early June to the middle of July in southwestern Alberta, and from late June to late July in west-central parts of the province.
- Golden trout spawn in small mountain streams. Occasional lake spawning has occurred for this species, but this is rare.
- Female golden trout dig nests, also known as a redds, and deposit eggs there for the males to fertilize. Fertilized eggs are covered with gravel by the females.
- Eggs incubate in the nest for more than a month before hatching.
Growth Process
- The short growing season of the high mountain lakes does not allow this trout to grow fast, and so most golden trout are small.
