Eggs are incubated undisturbed until the eyed stage is reached, in hatching troughs, vertical flow incubators or hatching jars. The oldest steelhead trout ever captured was 11 years old, and there have been reports of steelhead weighing up to 55 pounds! Superior characteristic selection is also achieved by cross breeding, increasing growth rates, resistance to disease, and profligacy, and improving meat quality and taste. But as the sportfishing industry began to lag, due to the distractions of technology and regulations, Bartosh has looked to diversify.

One advantage of this technique is that only the broodstock is sex-reversed, and they can be grown separately, while the marketed fish are not exposed to hormonal treatment. Rainbow trout can remain in freshwater their entire lives, or they can migrate to the ocean and then return to freshwater to spawn. Migratory forms of rainbow trout are generally slimmer than finally to 80C for 3/4 hour to 1 hour until the fish are cooked. Broodstock are selected for fast growth and early maturation (usually after 2 years).
