Resumo: | 1 PROBLEMA The relation between body weight and body length can be used to calculate the condition factor in fish. This factor express the grade of development of the fish. A sample of 253 fish from a hierarchial mating (5 females and 10 males) were used. Fishes were kept in net cages until, 150 days of age, and then marked and transferred to three tanks of I00m2/each; where they stayed until 330 days of age. The fishes were fed with a 30% crude protein and 2800 kcal/kg of metabolizable energy ration. Heritabilities of the alometric condition factor, from ages 90 to 300 days, were estimated using a model including female and mate within female. Heritabilities calculated from sire components of variance were: 0,28 ± 0,20; 0,11 ± 0,16; 0,24 ± 0,22: 0.20 ±0,19: 0,19 ± 0,19. respectively to 90, 150, 210. 270 and 330 days of age. These values suggest a small expected genetic gain from selection for this trait. |

A amostra era constituída de 253peixes, oriundos de acasalamento hierárquico (5 fêmeas e 10 machos), criados até a idade de 150 dias em tanques rede, e posteriormente marcados (conforme a família) e criados em 3 viveiros de 100m2 até a idade de 330 dias, com uma alimentação constituída de uma ração com 30% de proteína bruta e 2300 kcal de energia metabolízável. A determinação da herdabilidade do fator de condição alométrico, com idades entre 90 e 330 dias, foi feito pelo modelo que incluiu as variáveis; reprodutoras e reprodutores dentro de reprodutoras. Os valores de herdabilidade calculados através de componentes de variância paterno, foram; 0,28 ± 0.20; 0,11 ± 0,16, 0.24 ± 0,22; 0.20 ± 0,19; 0,19 ± 0,19, nas idades de 90, 150, 210, 270 e 330 dias, respectivamente. Os valores encontrados sugerem que a seleção para esta característica nas várias idades, deve proporcionar um valor baixo para o ganho genético.
