“…The fact that there is a large community of bivalve aquaculture in this area may limit the ability of the fan shell to attach to the long line, and once attached, they may be outcompeted for the limited space on the lines themselves. This interesting outcome does give a glimpse into the prospect of aquaculture of this species, presently under investigation worldwide (Beer & Southgate 2006, Leal-Soto et al 2011, Mendo et al 2011, in the future with existing aquaculture facilities and equipment such as on trays/cages (Acarli et al 2011b, Kozul et al 2013).…”

“…The culture of fan mussels in captivity has complications related to the small number of individuals to work with, their large size, which reduces the number of individuals that can be maintained in tanks, and the impossibility of growing collected seed in suspended culture in the open sea, as had been done priors to the mortality event (Kozul et al, 2012; Acarli, 2021). These circumstances make it necessary to find alternative solutions to obtain gametes and work on larval settlement as a key objective to close the life cycle in captivity.…”

A mass mortality event that started in 2016 has put the fan mussel Pinna nobilis close to the brink of extinction, leading to the species being classified as Critically Endangered in the Red List of the International Union for Conservation of Nature. Under current circumstances, with the persistence of the disease caused by Haplosporidium pinnae in the open sea, isolated populations in coastal lagoons and estuarine bays appear to be the main chance for the survival of the species. The low resilience of those populations highlights the importance of implementing additional measures to avoid the extinction of the fan mussel. One of these measures relies on completing its reproductive cycle in captivity. The reproductive window of the remaining fan mussel population in Alfacs Bay was explored to obtain gametes and to understand possible limitations in the reproductive activity in wild populations. For this purpose, during the reproductive season, several groups of individuals were relocated for short periods (~2 weeks) into the vivarium to obtain gametes under controlled conditions. Simultaneously, controlled temperature treatments and adapted food dosage for conditioning adult fan mussels out of their reproductive season in the wild were conducted in a recirculating aquaculture system. The reproduction of natural populations was mostly restricted to May, featuring temperatures around 20°C. A low success of spawning was obtained in the vivarium, with a 0% success in 11 out of 20 of the trials (six to nine individuals each) and an overall success of 16% (25 out of 156 individuals). A 100% success (14 out of 14) was obtained with individuals conditioned for ~2 months in the recirculating aquaculture system. A second conditioning of six of those individuals was attempted after a ~3‐month period, with a 33.3% success of spawning.

“…The target species of the present study, P. nobilis is the largest marine bivalve in the Mediterranean Sea (Vicente, 1990;Zavodnik et al, 1991) and is characterized by rapid shell growth during early ontogeny. It attains a shell height of 20-30 cm during first 2 years of life (Richardson et al, 2004;Kožul et al, 2012;García-March et al, 2020). In this study, average temporal resolution of δ 15 N CBOM from the external shell samples was 10 days, and this was obtained by milling ∼20-30 mg of carbonate material.…”

Pinna nobilis is a large bivalve endemic to the Mediterranean Sea that lives in shallow coastal areas. Due to its size and relatively fast shell growth rates, it is an interesting taxon for high-resolution study of nitrogen isotopes of carbonate bound organic matter (δ15NCBOM). In this study we tested if P. nobilis shells can be used as an indicator of the nitrogen isotope baseline of the system, if it can provide high-resolution data on environmental δ15N variability, and if the chemical properties of the shell and biomineralization process change in response to mass mortality events spreading in the Mediterranean. Shells were opportunistically collected during 2019 and 2020 by skin diving, as a part of a project on mortality monitoring, from four shallow coastal localities in the eastern Adriatic. Shell powder for δ15NCBOM analysis was collected by milling sample swaths from the internal (low-resolution) and external (high resolution) shell surface. Significant differences in δ15NCBOM, obtained from the internal shell surface, were observed between sampling localities with different anthropogenic influences, with lowest values (∼3–4‰) recorded for shells obtained from Pag Bay, and highest (∼6–8‰) for shells sampled in Lim and Kaštela Bays. High-resolution samples from the external shell surface of Pinna nobilis showed spatial and temporal variations in δ15NCBOM values, with temporal resolution of 1–3 weeks. High-resolution δ15NCBOM data obtained from the shell Kas1 corresponded to a time interval from spring 2018 to summer 2019 and had a pronounced increase of δ15NCBOM values closest to the shell margin coupled with a decrease in δ13Cshell values, indicating that this animal was experiencing stressful conditions several months prior to its death. According to our findings, δ15NCBOM values from P. nobilis shells can serve as an indicator of the isotopic baseline of the ecosystem potentially as a powerful tool to study bivalve physiology.
