ABSTRACT Following the increased mass mortality of Pinna nobilis populations in Mediterranean, reliable protocols for transport, maintenance, and controlled reproduction this highly endangered species were drawn up within European Life project. To test these protocols, large Pinnidae Atrina fragilis , which shares similar habits to P. has been used. In December 2022, a transport trial nine specimens A. from Trieste (NE Italy) Camogli (NW was carried out.

Abstract The Pinna nobilis , a Mediterranean mollusc, has suffered population declines due to massive mortality event associated with various factors including the parasite Haplosporidium pinnae . Some populations show resilience, possibly local environmental conditions. In this study, molecular multiplex PCR method was developed using species‐specific primers targeting Internal Transcribed Spacer (ITS) regions of P. and rudis allowing accurate species identification hybrid detection. Samples from areas were analysed, putative hybrids individuals five other bivalve species. DNA isolated, ITS amplified sequenced, phylogenetic analyses confirmed differentiation primer specificity. multiplex‐PCR successfully identified their based on distinct amplicon patterns. This study highlights value tools in conservation, especially for monitoring managing hybridization, supporting effective biodiversity conservation strategies.

Pinna nobilis, endemic to the Mediterranean Sea, has been experiencing a gradual population decline over recent decades due anthropogenic pressures on its ecosystems. However, since 2016, populations have suffered significant reductions because of pathological issues affecting species across all habitats. Aquaculture techniques support limited natural recruitment P. nobilis efforts is examined. Artificial substrates for larval attachments in aquaculture infrastructures promote survival juveniles that further enhanced through protected pre-growing “nursery” farming conditions. Specific spat collectors were placed 2 cage-fish farms SW Amvrakikos Gulf. The harvested spats from transferred pre-grow trays hanged long line farm mussel acting as “nursery”, avoiding predation and any human accidentally disturbance. growth 12 (shell length 38.1 ± 9.2 mm) captivity (31 October 2023–15 March2023) was investigated.
