The offspring of two steelhead parents may become a purely freshwater form of rainbow trout, while the offspring of two resident freshwater rainbow trout might evolve into an anadromous steelhead trout. YA/#,jai&,gT+f=c b3. However, current research and development is continually attempting to increase production efficiency and sales by increasing rearing densities, improving recirculation technology, developing genetically superior strains of fish for improved growth, controlling maturation and gender, improving diets, reducing phosphorous concentrations of effluents, and developing better marketing.
