20.500.12556/DiRROS-24900 Growth rates of the critically endangered fan mussel Pinna nobilis in the Slovenian sea (northern Adriatic) The fan mussel Pinna nobilis is a bivalve endemic to the Mediterranean Sea that is listed as Critically Endangered on the IUCN Red List. Its decline is due to a disease that has led to mass mortalities throughout the Mediterranean. The Gulf of Trieste (northern Adriatic) used to harbour one of the densest populations of P. nobilis, but since 2019, it has also been affected by this disease. The aim of this work was to analyse the growth of P. nobilis in the Slovenian part of the Gulf, with 3 case studies: (1) in situ measurement of adults before the mass mortality event (MME), (2) in situ measurement of juveniles after the MME and (3) ex situ measurement of juveniles kept in the laboratory. The pre-MME growth rate was comparable to that in other areas of the Gulf. In the first years of life, the growth rate of P. nobilis is higher than the growth rate reported in the southern Adriatic, and comparable to the growth rate in the Spanish lagoons. This is probably related to the physico-chemical conditions and confirms the potential of the area for restoration actions. Captive growth of juveniles could be an effective conservation measure, although juveniles kept in the laboratory grow more slowly than those in the sea, probably because of their lower immune response. Temperature plays an ambivalent role, as it increases the growth rate but also triggers the parasites responsible for the MME, which is of concern, given the recent rise of seawater temperatures and heatwaves. fan mussel model growth temperature conservation northern Adriatic sea veliki leščur temperatura rast modelov ohranjanje vrst severno Jadransko morje Pinna nobilis true false true Angleški jezik Slovenski jezik Neznano 2025-12-23 15:35:12 2025-12-23 15:35:12 2025-12-24 04:01:26 0000-00-00 00:00:00 2025 0 0 Soavtorji: Ana Fortič, Domen Trkov, Borut Mavrič, Ciril Mlinar, Lovrenc Lipej; str. 381-391 Vol. 58 2025 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 2025-12-04 502/504 1863-5407 10.3354/esr01455 261427971 https://doi.org/10.3354/esr01455 1 99156580-e00c-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=37270 RAZ_Pitacco_Valentina_2025.pdf RAZ_Pitacco_Valentina_2025.pdf 1 8292FE73812D91F2528B9303CBC285CD b3e2763e9a2ab2c71c108ac9d52f9ace584dba8ec9f0571922347623060617b5 3986c519-e00d-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=37271 Nacionalni inštitut za biologijo 0 0 0
