ANTÃO n= 17; n=20 The stock concept is fundamental as a baseline information in fisheries management, whose applicable definition depends on the specific issues that want to be resolved.
One of the most accepted definition is referred as an intraspecific group of randomly mating individuals with spatial and temporal integrity (Ihssen et al.
1981).
Nevertheless, the genetic stock concept is based on a reproductively isolated unit, which is genetically different from others stocks (Ovenden 1990).
Those two definitions share an important concept: random mating unit.
Thereby, population genetic analyses allow detecting the spatial scale at which evolutionary processes explain significant departures of admixture to test biogeographic hypothesis that elucidate the extent of genetic drift effect that enhance reproductive isolation.
The African Hind Cephalopholis taeniops is mainly distributed at the Eastern Atlantic, from Marroc to Angola, including Cape Verd, São Tomé and Principe islands (Pastor 2002, fishbase 2014, but see Brito et al.
2011 and Guidetti et al. 2010).
This species is one of the most important commercial demersal species in the Cape Verde archipelago and the consequences of population reductions due to an intensive fishing effort and the unknown geographic distribution of the stocks (Pastor 2002) are the main concerns towards fishery’s sustainability. Hence, the aim of the present study was to estimate island genetic diversity and to identify the genetic stocks across the archipelago to delimit discrete genetic units to contribute to an effective...
