AB In this study, we quantified the three key biological processes, growth, recruitment, anddispersal pattern, which are necessary for a better understanding of the population dynamics ofthe blue and red shrimp Aristeus antennatus. This marine exploited crustacean shows sex-relateddistribution along the water column, being females predominate in the middle slope. The presentstudy attempts to fill the existing gap in the females’ genetic demography, as scarce knowledge isavailable despite being the most abundant sex in catches. We analyzed morphometric data andgenotyped 12 microsatellite loci in 665 A. antennatus females collected in two consecutive seasons,winter and summer 2016, at the main Mediterranean fishing ground as a model. Almost every femalein summer was inseminated. Five modal groups were observed in both seasons, from 0+ to 4+ inwinter and from 1+ to 5+ in summer. Commercial-sized sorting based on fishermen’s experienceresulted in a moderate-to-high assertive method concerning cohort determination. Genetic datapointed out females’ horizontal movement between neighboring fishing grounds, explaining the lowgenetic divergence detected among western Mediterranean grounds. Our results could representcritical information for the future implementation of management measures to ensure long-timeconservation of the A. antennatus populations
