“…Elevated nitrogen excretion, indicative of protein breakdown expected during negative growth, was also found under low pH conditions (pH ~ 7.3) in the mussel Mytilus edulis (Michaelidis et al, 2005b). Notably, negative growth in juvenile oysters at low salinity and/or high P CO2 was associated with elevated mortality, indicating energy deficiency and supporting the notion that salinity and pH are among the key determinants of bivalve performance (including growth and survival) (Ringwood and Keppler, 2002;Heilmayer et al, 2008;Chapman et al, 2011).…”

“…Reduced salinity also lowers water CaCO 3 saturation levels (Cai and Wang, 1998;Miller et al, 2009) and has been shown to lead to decreased growth rates in C. virginica and other mollusks (Almada-Villela, 1984;Paynter and Burreson, 1991;Nagarajan et al, 2006;Heilmayer et al, 2008). In addition, negative effects of low pH and/or salinity on the organism's energy budget may also contribute to diminished shell deposition rates (Almada-Villela, 1984;Michaelidis et al, 2005b;Nagarajan et al, 2006;Heilmayer et al, 2008;Beniash et al, 2010).…”

“…Shell deposition rates decrease with increasing P CO2 in mollusks, and this change has been attributed to lower CaCO 3 saturation levels at the calcification site, which decreases the driving force for shell deposition and increases the dissolution of existing shell (Gazeau et al, 2007;Miller et al, 2009;Ries et al, 2009;Talmage and Gobler, 2009;Beniash et al, 2010;Talmage and Gobler, 2010).

SUMMARYRising levels of atmospheric CO 2 lead to acidification of the ocean and alter seawater carbonate chemistry, which can negatively impact calcifying organisms, including mollusks. In estuaries, exposure to elevated CO 2 levels often co-occurs with other stressors, such as reduced salinity, which enhances the acidification trend, affects ion and acid-base regulation of estuarine calcifiers and modifies their response to ocean acidification. We studied the interactive effects of salinity and partial pressure of CO 2 (P CO2 ) on biomineralization and energy homeostasis in juveniles of the eastern oyster, Crassostrea virginica, a common estuarine bivalve. Juveniles were exposed for 11weeks to one of two environmentally relevant salinities (30 or 15PSU) either at current atmospheric P CO2 (~400atm, normocapnia) or P CO2 projected by moderate IPCC scenarios for the year 2100 (~700-800atm, hypercapnia). Exposure of the juvenile oysters to elevated P CO2 and/or low salinity led to a significant increase in mortality, reduction of tissue energy stores (glycogen and lipid) and negative soft tissue growth, indicating energy deficiency. Interestingly, tissue ATP levels were not affected by exposure to changing salinity and P CO2, suggesting that juvenile oysters maintain their cellular energy status at the expense of lipid and glycogen stores. At the same time, no compensatory upregulation of carbonic anhydrase activity was found under the conditions of low salinity and high P CO2 . Metabolic profiling using magnetic resonance spectroscopy revealed altered metabolite status following low salinity exposure; specifically, acetate levels were lower in hypercapnic than in normocapnic individuals at low salinity. Combined exposure to hypercapnia and low salinity negatively affected mechanical properties of shells of the juveniles, resulting in reduced hardness and fracture resistance. Thus, our data suggest that the combined effects of elevated P CO2 and fluctuating salinity may jeopardize the survival of eastern oysters because of weakening of their shells and increased energy consumption.

“…The present study investigated the condition index (CI) as being an indicator of general oyster health as reported by Heilmayer, Digialleonardo, Qian, & Roesijadi, (2008). Furthermore, CI is a rapid measure of ecophysicological state (Lucas & Beninger, 1985;Yıldız & Lök, 2005) and considered as an economic indicator of market products (Orban et al, 2002).…”

Background: Salinity is one of the most consequential environmental stressors affecting marine organisms. Knowledge of salinity tolerance is of particular value to aquaculture. However, little is known explicitly about the salinity tolerance of oyster adult stage. The present study was designed to elucidate the salinity tolerance range of Pinctada imbricata radiata in order to determine the appropriate locations for grow out phase of pearl oyster culture and to assess the possibility of applying new "low salinity post-operative care" method that greatly enhance the pearl quality after implantation. The effects of extremely low and high salinities were quantified on the adult oyster survival and the ecophysiological state. Oysters were experimented in acclimated and non-acclimated sets in salinities ranged from 10 to 55 ppt (part per thousand). Results: It was found that the pearl oyster has a wide tolerance range of salinity. Within the optimal salinity range (25-38 ppt), no mortality was recorded. The mortality was significantly decreased and ceased in acclimated group as compared to non-acclimated in different ranges of salinities. Condition index (CI) of oysters reared in different salinities after acclimation and without acclimation showed considerable variations in particular, at low salinities. Conclusions: It is concluded that P. imbricata radiata can be reared in salinities up to 50 ppt during the growth phase. Low salinity post-operative care method can be applied on P. imbricata radiata after implantation by immersion in low salinities ranged between 20 and 25 ppt.

“…Temperature may also be considered one of the main abiotic factors affecting larvae, because it influences larval growth (Tettelbach & Rhodes 1981, Devakie & Ali 2000. Increases in temperature can intensify metabolic processes, as long as the critical upper temperature limit is not exceeded (Heilmayer et al 2008). Thus, larvae of different species require different optimal temperature conditions for maximal growth.…”
