Title: Restocking and stock enhancement of a commercially harvested sea urchin in Northern Spain : Genetic repercussions
Speaker: María Segovia Viadero
(University of Alicante, Spain)
Abstract: Human exploitation has drastically reduced the abundance and distribution of several invertebrates through overfishing and habitat destruction. Restocking can potentially mitigate these impacts and help to reconstitute depleted stocks but genetic repercussions must be considered. We studied the degree of genetic similarity between hatchery-reared sea urchins (Paracentrotus lividus, Lamarck 1816) for restocking purpose and the receiving populations in North of Spain using 9 microsatellites. Our findings indicate a low degree of genetic similarity between them, therefore this restocking initiative is not advisable. It is recommended to utilize broods from the same population for restocking purposes to provide a better genetic match to the wild populations.
