“…Accumulation of anaerobic metabolites is another reason why oysters cannot keep their shells closed after persistent stressful environmental challenges (Zubkoff and Ho 1982), such as low salinity. When bivalve molluscs are closed they accumulate anaerobic metabolic by-products such as succinate and fatty acids (Wijsman 1976;Zubkoff and Ho 1982) from the incomplete oxidation of glycogen for adenosine triphosphate generation through the tricarboxylic acid pathway (de Zwaan 1977). To extend the period they can remain shut under anaerobic conditions (closed shell) bivalves decrease their rate of metabolism (de Zwaan and Wijsman 1976;Hawkins and Bayne 1992;Hochachka and Somero 2002).…”

This study described seasonal differences in the histopathological and hemolymph chemistry changes in different family lines of Pacific oysters, Crassostrea gigas, in response to the stress of an abrupt change to low salinity, and mechanical grading. The most significant changes in pallial cavity salinity, hemolymph chemistry and histopathological findings occurred in summer at low salinity. In summer (water temperature 18°C) at low salinity, 9 (25.7% of full salinity), the mean pallial cavity salinity in oysters at day 3 was 19.8±1.6 (SE) and day 10 was 22.8±1.6 (SE) lower than oysters at salinity 35. Associated with this fall in pallial cavity salinity, mean hemolymph sodium for oysters at salinity 9 on day 3 and 10 were 297.2mmol/L±20(SE) and 350.4mmol/L±21.3(SE) lower than oysters at salinity 35. Similarly mean hemolymph potassium in oysters held at salinity 9 at day 3 and 10 were 5.6mmol/L±0.6(SE) and 7.9mmol/L±0.6 (SE) lower than oysters at salinity 35. These oysters at low salinity had expanded intercellular spaces and significant intracytoplasmic vacuolation distending the cytoplasm of epithelial cells in the alimentary tract and kidney and hemocyte infiltrate (diapedesis) within the alimentary tract wall. In contrast, in winter (water temperature 8°C) oyster mean pallial cavity salinity only fell at day 10 and this was by 6.0±0.6 (SE) compared to that of oysters at salinity 35. There were limited histopathological changes (expanded intercellular spaces and moderate intracytoplasmic vacuolation of renal epithelial cells) in these oysters at day 10 in low salinity. Mechanical grading and family line did not influence the oyster response to sudden low salinity. These findings provide additional information for interpretation of non-lethal, histopathological changes associated with temperature and salinity variation.

“…Mytilus edulis is an ideal species with which to examine inducible responses to hypoxic stress associated with aerial exposure because their distribution spans a steep stress gradient from the mid-intertidal, where aerial exposure is encountered daily, to the subtidal, where aerial exposure is never encountered. Studies that compared subtidally cultured mussels with wild intertidal mussels from a different site revealed that intertidal mussels had a higher tolerance for aerial exposure than those from the subtidal, and that cultured mussels acclimated to intertidal conditions could acquire a higher tolerance (Wijsman 1976, Sukhotin & Portner 1999. However, it remains to be examined whether differences in hypoxic tolerance exist between subtidal and intertidal portions of a natural mussel population and whether higher hypoxia tolerance in intertidal mussels is both gained and lost when mussels are reciprocally transplanted between the subtidal and intertidal.…”

The distribution of the blue mussel Mytilus edulis spans a steep gradient of environmental stress between intertidal and subtidal habitats, and can provide insight into population-scale patterns and underlying processes of variation in physiological tolerances. I conducted a 7 wk reciprocal transplant of mussels between the upper intertidal and subtidal portion of their natural depth distribution, and then assayed their tolerance to either aerial exposure or submerged hypoxia in the laboratory. Intertidal mussels transplanted back to the intertidal had a tolerance to aerial exposure 50% higher than subtidal mussels that remained in the subtidal. That difference can be explained by changes in mussel physiology induced by ambient conditions, since the tolerance of mussels transplanted between the intertidal and subtidal became similar to mussels occurring naturally in each habitat. The tolerance of mussels to submergence in hypoxic water -an environmental stress exacerbated by anthropogenic factors that experimental mussels had not encountered in the fieldfollowed a pattern qualitatively similar to the aerial exposure assay: intertidal mussels had higher survivorship in hypoxic water than those from the subtidal, and an elevated tolerance was induced by transplanting subtidal individuals to the intertidal. These results suggest that the response of mussels to a change in environmental conditions could vary between the center and edge of their depth distribution as a function of stress previously encountered.
