Pinna nobilis is a sensitive and vulnerable species and is hence considered a good indicator of anthropogenic pressures on marine ecosystems.

This study provides data on the density and distribution of P. nobilis on the coasts of Turkey, and assessed threats and the general awareness of people about the endangered status of fan mussels.

The results show that the density of fan mussels is highest around western coasts in comparison with the southern ones. The study also found that the number of damaged individuals was lowest in the areas that were distant from human influences such as ports and tourist beaches.

The authors state that fishers and divers indicated that the population of this species has decreased during the last decade. The main causes of this decline were suggested to be the impacts of fishing gear, poaching, pollution, and boat anchoring. The authors highlight that in general, the knowledge and local awareness of the conservation importance and status of fan mussels was poor.

It is highlighted that societal concern would benefit from educational activities to raise awareness of the ecological importance and conservation needs for fan mussels in Turkey.
