The sea urchin Paracentrotus lividus is one of the main herbivores of the Mediterranean coastal strip.
For the consumption of its gonads, much appreciated as a seafood speciality, the sea urchin is an important commercial resource, therefore it is a key species of the small local fishing and subject to sports and professional fishing in much of the Sardinian territory.
The monitoring of the Paracentrotus lividus carried out over the years has made it possible to contain the harvest in the MPA of Tavolara through specific regulatory indications both for professional and recreational pears.
