Genetic analyses reveal temporal stability and connectivity pattern in blue and red shrimp Aristeus antennatus populations

Abstract Temporal variability of the genetic structure and connectivity patterns of the blue and red shrimp Aristeus antennatus in the seven most important fishing grounds of the Western Mediterranean Sea, were assessed using twelve microsatellite loci during 2 consecutive years (2016 and 2017), in...
