Eggs usually hatch about a month after they are deposited and fertilized in mounds of stream-bed gravel. However, cold temperatures can delay the hatch for as long as an additional month. Newly hatched fry stay in the gravel and live off their attached egg sac until it is totally consumed. This usually takes four to six weeks. They then swim up and out of the gravel as fully formed fish.
