The Recruitment of the Endangered Fan Mussel Pinna nobilis (Linnaeus, 1758) on the Ropes of a Mediterranean Mussel Long Line Farm

ABSTRACT The fan mussel Pinna nobilis (Linnaeus, 1758) is an endangered bivalve species and is endemic to the Mediterranean Sea. Juvenile animals have been found growing on mussels Mytilus galloprovincialis (Lamarck, 1819) long line aquaculture bounces and ropes within the Maliakos Gulf (Aegean Sea). Animals were sampled from the harvested mussel lines. The results show twelve juvenile P. nobilis per ton of harvested M. galloprovincialis.
