Resumen
Growth and longevity parameters of males and females of Macrobrachium brasiliense were analyzed. Samplingwas carried out monthly from July 2012 to June 2013 in Triângulo Mineiro region, Minas Gerais, Brazil. A total of199 adult prawns (97 males and 102 females) were analyzed and measured according to the carapace length (CL, mm). Males (9.64 ± 4.17 mm, CL) were larger than females (7.7 ± 3.39 mm, CL). CL growth curves by the von Bertalanffy model are described by the equations CL = 21.0 [1 - e -0.00446 (t)] for males and CL = 20.0 [1 - e -0.00454 (t)] for females. Comparison of the growth curves by performing the F-type test, showed that there was no differencebetween the growth coefficients (K) of males and females (GL22; F3.16 = 2.476; p = 0.088). Longevity was estimated as 2.83 years for males and 2.78 years for females. In general, the observed longevity is similar to that of other Macrobrachium species.|Growth and longevity parameters of males and females of Macrobrachium brasiliense were analyzed.
