20.500.12556/DiRROS-23826 Recruitment and controlled growth of juveniles of the critically endangered fan mussel Pinna nobilis in the Northern Adriatic The fan mussel Pinna nobilis is the largest bivalve species in the Mediterranean Sea and provides numerous ecosystem services. It is classified as critically endangered by IUCN (International Union for Conservation of Nature) due to severe mass mortality events throughout the Mediterranean. The aims of this work are as follows: (i) to assess the current recruitment potential of the species, (ii) to enhance recruitment by keeping juveniles in controlled conditions before releasing them back into the sea, and (iii) to assess the health status of recruits. In the period 2022–2023, larval collectors were set up in the Gulf of Trieste as part of the LIFE Pinna project. The collected individuals were kept in aquaria in two different facilities under different conditions: (a) a closed system with constant water temperature, live phytoplankton, and commercial food and (b) an open system with ambient seawater temperature and commercial food. A clear temporal and spatial variability in recruitment was observed: 13 recruits were found in 2022 and 50 recruits in 2023. The live specimens were between 0.5 and 8 cm in size upon collection and larger in 2023. The growth and survival rate did not differ significantly between the two systems, but the average monthly growth and survival rate were related to the initial size of the juveniles. pen shell ex situ maintenance in situ maintenance Haplosporidium pinnae Mycobacterium conservation marine biology veliki leščur vzdrževanje ex situ vzdrževanje in situ Haplosporidium pinnae Mycobacterium ohranjanje morska biologija true false true Angleški jezik Slovenski jezik Neznano 2025-10-08 12:08:15 2025-10-08 12:08:15 2025-10-24 03:55:08 0000-00-00 00:00:00 2025 0 0 Nasl. z nasl. zaslona; Opis vira z dne 6. 10. 2025; Soavtorji: Domen Trkov, Daniela Caracciolo, Saul Ciriaco, Marco Segarich, Edoardo Batistini, Martina Orlando-Bonaca, Lovrenc Lipej, Borut Mavrič, Manja Rogelja, Ilenia Azzena, Chiara Locci, Fabio Scarpa, Daria Sanna, Marco Casu, Chiara Manfrin, Alberto Pallavicini and Ana Fortič; 1-18 str. iss. 10, [article no.] 666 Vol. 17 Oct. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-09-23 574 1424-2818 10.3390/d17100666 251937795 https://doi.org/10.3390/d17100666 1 b7389d6c-a42e-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35329 RAZ_Pitacco_Valentina_2025.pdf RAZ_Pitacco_Valentina_2025.pdf 1 6662DE991BC6213D94B9B067B09B44C2 821f9e5c33ab61b900341094aa5bd63eaceb937f690002df96fcfdd2e3b86bb4 097cd5f7-a431-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35332 Nacionalni inštitut za biologijo 0 0 0
