摘要

Most animal breeders are interested in selecting for several traits, but selecting one trait at a time is inefficient. A more efficient method of improving catfish breeding stock is to select individual males and females with traits this study showed to be heritable, but using an index developed from the heritability estimates weighted with dollar values assigned to the desired traits. Using results of this study for weight at 18 months and length at 90 days gives an index for the Tupelo strain of catfish. The length and weight used in calculating the index represents fingerlings for stocking and food fish.
