“…Temperature has also been observed to influence the filtration rate and assimilation efficiency of bivalves (Widdows & Bayne ). To date, there have been many studies on the effects of temperature on the metabolic responses in marine bivalve molluscs, for example, Chlamys farreri (Yang, Zhang, Wang, He & Zhang ), Meretrix meretrix (Tang, Liu, Yang & Xiang ), Pinctada mazatlanica (Saucedo, Ocampo, Monteforte & Bervera ), Corbicula fluminea (Xiao, Li, Du, Jiang, Chen & Yu ) and Pinna nobilis (Trigos, Rafael Garcia‐March, Vicente, Tena & Torres ).…”

The metabolic responses of different colour strains of Ruditapes philippinarum in terms of oxygen consumption and ammonia excretion to changes in temperature (15-35°C) and salinity (20-40) were investigated. In our range of temperatures (15-35°C), oxygen consumption rate (OCR) increases in cultivated strains (White and Zebra) in opposition to the effect in the wild strain which reach a maximum at 25°C. The highest Q 10 coefficients were 2.741 for zebra strain, 4.326 for white strain, and 1.944 for wild at temperatures of 25-30, 30-35 and 20-25°C respectively. In our range of salinity (20-40°C), OCRs of white strain and zebra strain firstly decreased to lowest level at 25 and 30, and then increased to highest level at 35 and 40 respectively. When the salinity is beyond 35, the OCR decreased and the turning point was found in the white strain and wild, but the zebra strain OCR still increased to a highest level (1.906 mg g À1 h À1 ) at 40 (P < 0.05). These results show that the cultivated colour strains of R. philippinarum were different from wild in terms of metabolic responses, and information on its response to different temperature and salinity have implications in the aquaculture industry.

“…These conditions induce extended physiological stress, which reduces the resistance of the host organisms to proliferating pathogens (Cerrano et al 2000). Similarly, high seawater temperatures during the summer months may have lowered the physiological capacity of P. nobilis to resist parasite infections due to a high respiratory demand at increased temperatures (Trigos et al 2015), which subsequently enhanced parasite manifestation. Unfortunately, the environmental cues that have triggered H. pinnae proliferation and virulence are currently unknown, and cannot be easily inferred from closely related parasite species, as haplosporidans flourish under contrasting environmental conditions (Arzul and Carnegie 2015).…”

The cryptogenic parasite Haplosporidium pinnae has caused mass mortality of the protected endemic Mediterranean bivalve Pinna nobilis in the western Mediterranean, since the autumn of 2016. Herein, we confirm the spread of the parasite in the eastern Mediterranean, and report a mass mortality event, with > 93% average mortalities, in the coastal waters of Lesvos Island (Greece, Aegean Sea). Histopathological study of collected specimens revealed the presence of a haplosporian-like protozoon in different life cycle stages, mainly within the digestive gland of the infected Pinna nobilis, with many uni-and bi-nucleate parasite cells, plasmodia and sporocysts in the wide lumen of digestive tubules causing the collapse of epithelial cells, and apparently low host haemocyte reaction. The parasite was identified as H. pinnae by molecular methods (PCR amplification and sequencing of a part of small subunit ribosomal DNA gene, and comparison with available records in Genbank). In many sites, 100% mortality was recorded, whereas in a single site (among 13 surveyed sites) mortality was relatively low (36%), successful recruitment was observed and the parasite was not detected. The latter observation stresses the importance of possible parasite-free refugia sites. We call for continuous monitoring of the spread of the parasite and its impacts, and for urgent targeted research and actions to identify the factors affecting the parasite's virulence, investigate biotic and abiotic conditions that characterize refugia sites, and strictly protect the remaining P. nobilis populations to increase the chances for the survival of the species.

“…Small groups of 4-6 individuals were placed in two 120 L tanks within controlled temperature facilities (20-21 °C) with filtered (1 μm) and treated (UV) seawater for a maximum of 24 h. A ≈ 10 °C gradient is necessary to induce a thermal shock causing gametes release in bi-valves (Helm et al, 2006) which takes place at various temperature thresholds, depending on the species (Drent, 2004). Herein, in order to keep this temperature gradient two induction tanks were prepared; one tank was maintained at 15 °C while a second tank was heated to 25 °C thus respecting the conformability range of temperatures described for P. nobilis (Trigos et al, 2015).…”

The development of aquaculture activities has posed an alternative solution for the preservation of some overexploited shellfish fisheries worldwide. In the same way, endemic Mediterranean bivalves such as Pinna nobilis, highly threatened by habitat loss and coastal pollution, could found in aquaculture a solution for preserving the continuity of the species. Given the endangered status of the species, the biological and ecological processes regulating natural populations have been well studied, but there are still important knowledge gaps preventing the development of viable artificial cultures. This study describes for the first time the larval development of P. nobilis (from fertilization until pediveliger larval stages) in captivity conditions. Moreover, different rearing tanks of 5, 16 and 80 L, larvae density from 1 to 600 larvae mL −1 , light conditions, food doses, were tested in order to establish the bases for the optimal rearing of the species and provide a source of individuals for restoring field populations. Results showed that 16 L tanks with a concentration of 2 larvae mL −1 , constant temperature of 21 °C, 12/12 h photoperiod and fed with an "optimal" mixture of 25 cells per μL of Chaetoceros calcitrans + 33.3 cells per μL ofPavlova lutheri + 100 cells per μL of Isochrysis galbana" appear to be the best conditions to rear larvae of P. nobilis. Different captivity conditions such as lower or higher tank volume, larvae density, or food doses; light privation did not report better results for larval development.
