First assessment of restocking efficacy of the depleted sea urchin Paracentrotus lividus populations in two contrasted sites.

The removal of wild sea urchins from S2 ( I N i ~ 150) was carried out before the beginning of the trial to avoid a mixing effect with the reared urchins. These results indicate that reared sea urchins were able to forage once seeded into the wild confirming that sea urchins used the available seaweeds and animal proteins as source of food (Prato et al., 2018).
