An unprecedented mass mortality event is impacting Pinna nobilis populations throughout the Mediterranean Sea. Therefore, it is extremely important to assess larval recruitment to evaluate if larvae coming from unaffected sites or resistant individuals are reaching the impacted areas, thus potentially contributing to eventual recoveries.

Larval collectors have been successfully used to assess P. nobilis recruitment in different contexts and areas. Additionally, if needed, this methodology might eventually be used to provide juveniles to restock populations.
