Pinna nobilis, whose common name is the noble pen shell or fan mussel, is a large species of Mediterranean clam, a marine bivalve mollusc in the family Pinnidae, the pen shells. It reaches up to 120 cm (4 ft) of shell length. It produces a rare manganese-containing porphyrin protein known as pinnaglobin. Parasite causing massive outbreak of Mediterranean penshell Pinna nobilis continues to extend rapidly, revealing need for further and urgent action.Following a first outbreak in 2016, which caused the mortality of around 99% of the population in Spain, the spread of a disease caused by an haplosporidian parasit and perhaps other mycobacteria is.

A newly described Haplosporidian endoparasite ( Haplosporidium pinnae) is the most probable cause of this ecological catastrophe placing one of the largest bivalves of the world on the brink of. Abstract The fan mussel, Pinna nobilis, endemic to the Mediterranean Sea, is a critically endangered species facing mass mortality events in almost all of its populations, following the. Open access Published: 17 November 2022 Population status, distribution and trophic implications of Pinna nobilis along the South-eastern Italian coast Davide Pensa, Alessandra Fianchini, Luca. 1. Introduction. The pen shell Pinna nobilis (Linnaeus, 1758), reaching a size of up to 120 cm (Zavodnik et al., 1991), is the largest bivalve of the Mediterranean Sea (where it is endemic), and ranks amongst the largest in the world.It occurs at depths between 0.5 and 60 m, mostly on soft-bottom areas overgrown by seagrass meadows, but also occasionally on bare sandy substrate and maërl beds.

The case. The fan mussel Pinna nobilis (Linnaeus, 1758), an endemic and protected bivalve of the Mediterranean Sea, is affected by a Mass Mortality Event (MME) provoked by the parasitic protozoan Haplosporidium pinnae started in 2016 in Spanish waters. The populations of Pinna nobilis in the open sea have almost completely disappeared from the Mediterranean coasts, with a mortality rate close. The pen shell Pinna nobilis (Linnaeus, 1758) is the largest endemic bivalve mollusc of the Mediterranean Sea, listed as an endangered species in the European Union. The fan mussel, Pinna nobilis, represents the largest bivalve endemic to the Mediterranean Sea.Since 2016, dramatic mass mortality of this species has been observed in several areas. The first surveys suggested that Haplosporidium pinnae (currently considered species-specific) was the main etiological agent, but recent studies have indicated that a multifactorial disease may be responsible for. 33 researchers and representatives from the public administrations from 13 Mediterranean countries engaged in an online meeting facilitated by IUCN-Med, to present the latest mortality data and progress to recover the Critically Endangered (CR) populations of Pinna nobilis, now included on the IUCN Red List of Threatened Species™.

Introduction. The pen shell, Pinna nobilis Linnaeus, 1758, is one of the most imposing endemic bivalves in the Mediterranean (MacDonald and Barrett, 2008). It reaches up to 120 cm in size (García-March et al., 2007) with a suggested age of up to 45 years (Rouanet et al., 2015) and can be found in coastal areas at depths of 0.5 - 60 m (Templado et al., 2004). A European Union-supported project to protect the Pinna Nobilis, known as the 'noble pen shell' or 'fan mussel,' a species formed 20 million years ago and now at risk of extinction due to climate change, is underway in Italian and Slovenian waters.
Recently, Pinna nobilis pen shells population in Mediterranean Sea has plummeted due to a Mass Mortality Event caused by an haplosporidian parasite. In consequence, this bivalve species has been included in the IUCN Red List as "Critically Endangered". In the current scenario, several works are in progress to protect P. nobilis from extinction, being identification of hybrids (P. nobilis x. Pinna nobilis is a protected Mediterranean species and is particularly endangered because, in addition to direct threats from collection and predation, its populations are declining as a result of the widespread decline of P. oceanica across the western Mediterranean.

From May to October 2019, multiple mass mortality events (MMEs) of Pinna nobilis were observed along Croatian coastline starting from the south-east and rapidly progressing in north-western direction. Time dynamics of the MMEs closely followed general speed and direction patterns of surface sea-currents, advancing approximately 350 km in less than 3 months. Surveillance, clinical evaluation. The noble pen shell Pinna nobilis is a Mediterranean endemic and emblematic giant bivalve. Already considered by the late 20th century to be an endangered species, it is facing a dramatic and rapidly expanding epizooty that has decimated populations since mid-2016.
