Pen shell video on larvae collectors promoted through the Croatian Marine Protected Areas Network (CROMPA)

Given the recorded mass mortalities of the noble pen shell in the Med, including in the Adriatic Sea, several enthusiasts of the scientific and professional community gathered in a joint initiative PinnAdriaNet.

Given the recorded mass mortalities of the noble pen shell in the Mediterranean sea, including in the Adriatic Sea, several enthusiasts of the scientific and professional community gathered in a joint initiative PinnAdriaNet with the aim of rescuing a strictly protected and now critically endangered species.

Collectors have been set up throughout the Adriatic to collect the larvae, which would then be planted in controlled growth conditions, thus increasing the probability of the species' survival. The eventual recovery of affected populations will depend largely on the existence of intact populations, resilient individuals, and recruitment. Therefore, it is extremely important in the medium and long term to monitor the recruitment of juvenile noble periwinkles to assess whether there are intact or even resistant individuals or populations.

With the aim of disseminating knowledge, CroMPA organised a presentation of a new video on the construction of larvae collectors on a permanent mooring line. The video was produced by the Natural History Museum from Split in cooperation with the Public Institution Sea and Karst within the project of preserving the Noble pen shell (Pinna nobilis) in the Adriatic Sea.
