| description | Weight gain and morphometric growth of the genetically improved tambaqui (Colossoma macropomum) are evaluated. Current assay was carried out on the Fish Farm Experimental Station of the Federal University of Mato Grosso, in the municipality of Santo Antonio de Leverger - MT Brazil. Seven fish families from the breeding program and a control group (not genetically improved) were evaluated. All animals were individually identified with a transmitter-responder label (transponder). Weight gain, overall and standard length, head size, height, width and body perimeter were measured. A completely randomized design was used and comparisons among families and the control group were carried out by Dunnett test at 5% significance level. The genetically improved fish families showed a 14.8% higher weight gain when compared to that of control group. Five out of seven families showed greater weight gain when compared to control group, with the best family exhibiting a 24.8% higher rate. Four families had higher growth in all evaluated morphometric characteristics when compared to control group. Only one family did not differ in any of the evaluated characteristics with regard to the control group. |
