Microsatellite markers for the hake Macruronus magellanicus amplify other gadoid fish

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 exploitation occur...

Description
Summary: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 exploitation 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genetic data available, detected no differentiation among coastal and offshore samples (M. E. D'Amato & G. R. Carvalho, unpublished), indicating a need to develop more polymorphic markers such as microsatellites.
