“…Nevertheless, extreme fluctuations in salinity can defeat the defences and cause varying degrees of damage to marine molluscs, even may lead to heavy mortalities and economic losses Gagnaire et al, 2006;Gajbhiye & Khandeparker, 2017). Among marine molluscs, previous studies are mostly concerned with the effects of salinity on behavioural response (Vasquez et al, 2021;Woodin et al, 2020), haemolymph chemistry and histopathological changes (Knowles et al, 2014), immune response (Casas et al, 2018;Gharbi et al, 2016;Zhang, Li, et al, 2020), gene expression (Gong et al, 2020;Nie et al, 2017) and molecular response (Li et al, 2021;Ni et al, 2021) in species such as Crassostrea gigas, C. nippona, C. virginica, Ruditapes philippinarum, R. decussatus, Cyclina sinensis, Sinonovacula constricta, Pteria penguin and Venerupis corrugate. Therefore, more knowledge is needed to understand the effects of acute salinity stress on the physiological and biochemical factors of other marine bivalve molluscs.…”

Salinity change is a frequently occurring abiotic stress that dramatically affects the physiological and biochemical factors of marine bivalve molluscs. In this study, a total of 140 individuals of Pinctada maxima were collected from Weizhou Island (Beihai, China) for 48‐h acute salinity stress. Immune enzymes (phenoloxidase [POX], lysozyme [LZM] and alkaline phosphatase [ALP]), antioxidant enzymes and substances (superoxide dismutase [SOD] and reduced glutathione [GSH]) were measured at different times after acute low‐salinity (salinity 20) and high‐salinity (salinity 40) stress with a salinity of 30 as the control group to assess the effects of acute salinity stress on immune and antioxidant responses of P. maxima. The results showed that the total protein (TP), GSH, SOD, POX, LZM and ALP of silver‐lipped pearl oyster P. maxima were significantly influenced by the different salinity gradients and duration of salinity stress (p < 0.05). The TP, SOD, LZM and GSH of P. maxima recovered to the same level of the control group at 48 h after acute high‐salinity stress (salinity 40, p > 0.05), while only TP and LZM in the low‐salinity group (salinity 20) recovered to the same level of the control group at 48 h (p > 0.05), indicating that P. maxima has a stronger tolerance to high salinity (40) than low salinity (20). The study provides references for exploring the antioxidant and immune response mechanism to salinity stress in P. maxima and its cultivation.

“…Temperature and salinity are two of the most important physical factors affecting intertidal organisms, such as bivalves, playing an important role on their abundance and distribution (Gosling, 2004;Booij, 2005;Gharbi et al, 2016). While temperature is considered to affect energy balance and level of activity (Sobral and Widdows, 1997), salinity has an influence on physiological processes (Navarro and Gonzalez, 1998;Carregosa et al, 2014).…”

The Impact of Climate Change on Bivalve Farming: Combined Effect of Temperature and Salinity on Survival and Feeding Behavior of Clams Ruditapes decussatus

et al. 2022

European clam (Ruditapes decussatus) is one of the most relevant emergent bivalve species from the aquaculture sector in Europe with high economic value. Climate changes represent a potential limiting factor to this activity, directly interfering with the survival and behavior of bivalves. Severe fluctuations in temperature along with periods of heavy rainfall or periods of drought that significantly change the salinity can promote physiological stress in bivalves, resulting in changes in physiological and behavioral responses and, in extreme cases, leading to high mortalities. This study aimed to evaluate the combined effect of temperature and salinity on mortality and feeding behavior of R. decussatus. Juveniles and adults were exposed to combined ranges of temperature (5°C–35°C) and salinity (0–40). Mortality and feeding behavior were registered every 24 h of each 120-h trial. A control temperature range was set between 15°C and 23°C, where mortality and feeding behavior were considered as the normal scenario. Our data suggested salinity 15 as a “turning point,” a point from which occurred distinct patterns in mortality and feeding behavior. The results evidently indicate that abrupt reductions in salinity and sharp increases in temperature will lead to high mortality of R. decussatus. Juveniles were revealed to be more sensitive to the increase of temperature in a less saline environment, to suffer greater and faster mortalities, and to be more resistant to extremely high temperatures under more saline conditions. The high temperatures and sporadic heavy rainfall that are predicted to occur in the south of Europe due to climate changes will contribute to compromise the recruitment of European clam, thus threatening the production of this species and consequently impacting the economic sector.

“…Major factors limiting the reproduction, settlement and growth are: temperature (maximum survival 31°C), food availability (mainly diatoms), sediment grain size (optimum 70-80% of sand), turbidity, dissolved oxygen (optimum 6-8 mg l -1 , minimum 3.5 mg l -1 ) (PAESANTI & PELLIZZATO, 2000). Although Ruditapes philip-pinarum show high adaptability and resistance compared to R. decussatus (GHARBI et al, 2016), the deterioration of the environment due to several anthropic disturbance sources and the overfishing threaten the wild populations.…”

The Manila clam, Ruditapes philippinarum, introduced in the Venice lagoons in 1983 and rapidly spread to the nearby coastal lagoons represents one of the most important commercially-exploited resources of this area. Abundance, size-class and biomass distribution of the wild population living in the Pialassa Baiona lagoon were assessed and related to the hydrological and sediment characteristics. Despite the lagoon being affected by eutrophication, chemical and thermal pollution, the clams were harvested by about thirty professional fishermen until 2003. The commercially available stock was estimated at 36.8 10 3 kg in July 2002, 29.3 10 3 kg in April 2003, and 10.3 10 3 kg in October 2003. Stock estimations and observed mortality were in good accordance with the fishermen data. The decline of the available stock could be due to both overfishing and the extraordinary summer heat wave occurred in 2003, which may have reduced larval recruitment and increased the mortality. Overall, the juvenile recruitment appeared insufficient to annually restore the natural stock. Although the national and regional high relevance of clams market, local harvesting of wild populations appeared marginal and inadequate to support a remunerative commercial activity, due to the variability and unpredictability of the annual yield and the lack of a sustainable management based on a production chain’s approach.

Response of the carpet shell clam (Ruditapes decussatus) and the Manila clam (Ruditapes philippinarum) to salinity stress

Abstract: Environmental stressors are known to play an important role in determining the distribution and abundance of intertidal species. Marine molluscs are particularly susceptible to changes in water temperature and salinity in inter-tidal zones.
