[font "Arial"][size 4]Like other cutthroat trout, the Bonneville cutthroat spawns in the spring. Spawning usually takes place when the water is between 43-59 degrees F. Trout change color when they are about to spawn. A female will seek out a slowly moving stretch of water. It is here that she will begin to build the redd, a nest for the eggs. She begins by lying on her side. She starts moving her tail back and forth causing gravel and other material to be moved out of the way. She keeps doing this until she has a redd that is four to six inches deep.

[font "Arial"][size 4]After the redd is finished the female swims over the top of the redd and waits for a male to join her. They deposit eggs and milt into the redd she has built, where fertilization will occur. The male swims off to the side and the female goes slightly downstream where she lays on her side and covers the redd with gravel, thus creating a new redd. The female may or may not use this new redd. A male and female are capable of repeating this process many times.

[font "Arial"][size 4]The eggs hatch in about three weeks at a temperature of about 54 degrees F. The newly hatched trout depend on their yolk sac for nourishment and as they grow the yolk sac slowly disappears.
[/size][/font]
[font "Arial"][size 4]The process of spawning is virtually the same for the Rainbow trout. Spawning is triggered by warmer water temperatures, which occur in spring from February to June. The amount of eggs a female lays is directly related to her size. Eggs should be incubated between 41 and 59 degrees F.[/size][/font]
