The long-tail hake Macruronus magellanicus is a demersal pelagic species that constitutes the most abundant fish resource in the southwestern Atlantic (Prenski et al. 1996). However, the fisheries have only recently developed and stock identification is required before large-scale exploita- tion occurs. However, ecological (R. Gonzalez, B. Prenski, personal communication) and morphological (A. Giussi,personal communication) data suggest stock differentiation in Patagonian gulfs. Mitochondrial DNA (mtDNA) restriction fragment length polymorphism (RFLP), the only genetic data available, detected no differentiation among coastal and off- shore samples (M. E. D’Amato & G. R. Carvalho, unpublished), indicating a need to develop more polymorphic markers such as microsatellites.
