Abstract
Five generations of mass selection for length and condition factor were undertaken with a Cuban commercial strain of Oreochromis aureus known as LK from 1985 to 1990. Genetic gains were assessed against a large unselected control population drawn at random from the original founder population. The control and selected line were grown in separate but replicated ponds under identical husbandry and feeding regimes. The average genetic gain per generation were 25.6 g, 11.2 g and 17.7 g for males, females and combined sexes respectively. Realised heritabilities over five generations were h2 = 0.126 for males, hZ = 0.13 for females and h* = 0.19 for the combined sexes.
