Integration of spatial distribution of genetic variability for aquaculture development and regulations, the European perch case

Original language description

Knowledge of spatial genetic variability (i.e. differentiation and diversity) patterns is key information for production and trade strategies of species. It allows improving conservation actions, translocation regulations, and farming productivity. By taking into account lessons from the past, we investigate the genetic variability of Perca fluviatilis, a fish species at a nascent stage of its aquaculture, in order to promote a more sustainable aquaculture. We characterise the genetic variability across 84 West-Palaearctic sampling sites using four mitochondrial sequences and eight microsatellites. By considering this variability, we aim to provide (i) a genetically-based population structure that could act as an impetus for further improvement of P. fluviatilis production and (ii) guidelines for efficient regulations of the translocations of the species within its natural range. Our analyses show an uneven distribution of the genetic variability across the species range. Based on genetic differentiation, we identify five large geographic scale clusters which are further divided into several subgroups. Mapping of genetic diversity highlights several hotspots across the species range. This spatial pattern of intraspecific diversity implies to develop specific and appropriate regulations of translocations. Moreover, we observe similarities between geographic differentiations in genetics and in zootechnical performances previously reported. We ultimately propose intraspecific regulations for further investigations of population-specific performances in aquaculture and potentially efficient regulations for policy-makers.
