The result of genetic variation is obvious to every channel catfish farmer. Differences in growth, body shape, and color can be seen even in fish from the same spawn and reared in the same environment. In nature, genetic variation is important because it enables populations to adapt to changing environments and survive. Genetic variation is important in channel catfish farming because the heritable component of variation can be exploited through breeding programs to improve commercially important traits.
