| Abstract: | The patterns of genetic variation in a fragment of the cytochrome b mtDNA gene in 130 individuals of the fat snook (Centropomus parallelus) did not show evidence of genetic differentiation along the Brazilian coast as shown in F‐statistics and AMOVA analyses, indicating the existence of high gene flow among the studied populations. In addition, the study of the evolutionary demography of the species using mismatch distribution analysis and statistical tests such as Tajima’s D and Fu’s F indicate that it experienced a pattern of population expansion during its recent evolutionary history. |
