The age of a 20-inch rainbow trout can vary significantly based on environmental factors, growth rates, and habitat conditions. Generally, in favorable conditions, a rainbow trout may grow about 1 inch per year, suggesting that a 20-inch trout could be around 5 to 7 years old. However, in optimal environments, some may grow larger and faster, potentially making a 20-inch trout older than 7 years. Ultimately, age estimates can differ widely depending on local conditions and food availability.
They can mate at any time of the year but only when conditions are exactly right for them to do so.
