Paracentrotus lividus is a widely distributed species in the Mediterranean Sea and North-East Atlantic Ocean, where it plays an important ecological commercial role. The growing demand for its delicious gonads has rapidly led to overexploitation of natural populations around Sardinia (western Mediterranean). present research aimed at understanding population genetics within area, gathering data on juveniles produced experimental 'conservation hatchery' facility. A multilocus approach was used, combining mitochondrial genes (COI Cytb) microsatellite markers. Overall, both microsatellites results indicate that hatchery-produced were less genetically diverse significantly divergent from wild populations, most likely because bottleneck effect due insufficient number parental breeders used. As concerns despite high harvesting pressure, they still have good quantity genetic variation. weak overall differentiation found, suggesting extensive gene flow among sites. However, pairwise comparisons between Sardinian samples found be significant with regard sequences, further investigated additional studies. These provide scientific knowledge necessary inform future management actions improve aquaculture protocols.
