Maximizing Offspring Production While Maintaining Genetic Diversity in Supplemental Breeding Programs of Highly Fecund Managed Species

Article Abstract:

Four supplemental breeding designs are assessed involving monogamous pairings and complete factorial designs, both with and without an additional stipulation that total reproductive output consists of equal contributions by all breeders. A complete factorial design has the potential to increase production in robust redhorse (Moxostoma robustum) fish by 19%.
