Parental contribution in a cultivated stock for the spotted rose snapper Lutjanus guttatus (Steindachner, 1869) estimated by newly developed microsatellite markers

ABSTRACT The spotted rose snapper Lutjanus guttatus is a fishery relevant species from the eastern Pacific Ocean, with aquaculture potential. Species-specific genetic markers are needed for the genetic characterization of wild and cultivated populations to help management strategies. Eighteen hyperv...
