“…The reported effects of an increase in temperature include changes in growth [10,11], behavior [12,13], metabolism [14,15], and mortality [12,16]. Salinity effects include abnormal endogenous rhythms [17], changes in behavior [18][19][20], decreased condition index [21,22], and increased mortality [23]. Short-term temperature and salinity stressors, such as heatwaves and heavy rainfall, can threaten growth, recruitment, and survival at the population level [24,25].…”

This article investigates the response of the Manila clam Venerupis philippinarum to possible temperature and salinity changes in a holding facility. First, clams are exposed to four temperatures for 15 days. Valve closure and survival of clams exposed to seawater at 18 °C are higher than those exposed to seawater at 24 °C. Second, clams are exposed to six salinities for 15 days. Survival of clams exposed to two salinity fluctuation conditions (24–30 and 27–24 psu) is lower than that of clams exposed to constant 30 psu conditions. Valve closures of clams exposed to constant low salinity conditions (24 psu) and two salinity fluctuation conditions (24–30 and 27–24 psu) are higher than those exposed to constant 30 psu conditions. Lastly, clams are exposed to two different temperatures and three different salinities conditions for eight days. Valve closure and survival decreased significantly under the combination of 24 °C and 18 psu. These results suggest that an increase in temperature or a wider range of salinity fluctuations are detrimental to the survival of the Manila clam. The synergistic effect of temperature and salinity stressors may decrease the survival period of clams compared to the effect of a single stressor.
