Growth rate and maximum size of Mytilus edulis is much lower in the Baltic Sea (7 %o S) than in the North Sea (28 %O S). Reciprocally transplanted mussels grew at rates similar to those of native mussels at each site, indicating that this variation can largely be explained by physiological differences due to environmental salinity Initial sunrival of Baltic mussels was very high after transfer to the ma.rin.e environment both in 1984 and 1986, but was followed by very high mortality in the follow~ng late summer In contrast immediate mortality was over 90 O/O among North Sea mussels transferred to the Baltic Sea with only some of the smallest mussels surviving. These, however, suffered no further excessive mortality. These different survival rates probably have mainly genetic causes. Genetic factors also seem to explain morphological differences, since these were to a large extent maintained even more than 1 yr after transplantation. Native North Sea mussels had 24 % larger volume and 9 % greater shell hei9h.t than transplanted Baltic mussels of the same length (48 mm), while shell width differed little. Total dry weight and shell weight were about 2 times larger in North Sea than in transplanted mussels, and weights of meat and posterior adductor muscle were 1.6 times and 3.3 times larger, respectively. However, in mussels of Baltic origin more biomass was allocated to meat (14.7 O/o of total dry wt) relative to shell and adductor muscle, than in North Sea mussels (11.2 %). Predation experiments with Asterias rubens showed that Baltic mussels grown for 12 mo in the North Sea were more readily attacked and more easily opened than equal-sized North Sea mussels. We suggest that the lack of thck shells and large adductor muscles is caused by low predation pressure in the Baltic which does not select for such protective characters. Relatively more of the available energy instead seems to be allocated to reproduction.

“…Temperature, however, seems to have a negative effect on calcification starting already at the early stages in this study. Malone and Dodd [105] reported a positive effect of temperature on calcification rates of adult M. edulis, but also that variability among individuals increased strongly with increasing temperature. This variation was partly explained by some individuals that did not calcify during the 24-h experimental period.…”

Larval stages are among those most vulnerable to ocean acidification (OA). Projected atmospheric CO 2 levels for the end of this century may lead to negative impacts on communities dominated by calcifying taxa with planktonic life stages. We exposed Mediterranean mussel (Mytilus galloprovincialis) sperm and early life stages to pH T levels of 8.0 (current pH) and 7.6 (2100 level) by manipulating pCO 2 level (380 and 1000 ppm). Sperm activity was examined at ambient temperatures (16-17• C) using individual males as replicates. We also assessed the effects of temperature (ambient and ≈20• C) and pH on larval size, survival, respiration and calcification of late trochophore/early D-veliger stages using a cross-factorial design. Increased pCO 2 had a negative effect on the percentage of motile sperm (mean response ratioR = 71%) and sperm swimming speed (R = 74%),Water 2013, 5 1891 possibly indicating reduced fertilization capacity of sperm in low concentrations. Increased temperature had a more prominent effect on larval stages than pCO 2 , reducing performance (R Size = 90% andR Survival = 70%) and increasing energy demand (R Respiration = 429%). We observed no significant interactions between pCO 2 and temperature. Our results suggest that increasing temperature might have a larger impact on very early larval stages of M. galloprovincialis than OA at levels predicted for the end of the century.

“…As with many other physiological processes, shell production is significantly influenced by temperature, with numerous reports showing higher shell growth rates with increasing temperatures (e.g. Malone and Dodd 1967), optimal temperature levels (Almada-Villela et al 1982) and opposite The calcification of the growing shell takes place at the distal border of the shell, in a compartment-the extrapallial space containing the extrapallial fluid-enclosed by the calcifying epithelium, the periostracum and the shell itself Mar Biol effects of acute versus chronic exposure to higher temperatures (e.g. Nielsen 1988).…”

“…Among these other factors, salinity has received considerably less attention with some reports of increased shell growth with increases in salinity over short incubation periods (e.g. Malone and Dodd 1967), the capacity to acclimate over several weeks to abrupt changes in salinity (Almada-Villela 1984) and combined effects of food availability, temperature and salinity on the survival and growth of larvae (Davis and Calabrese 1964).…”

Impacts of ocean acidification on marine shelled molluscs

Over the next century, elevated quantities of atmospheric CO 2 are expected to penetrate into the oceans, causing a reduction in pH (-0.3/-0.4 pH unit in the surface ocean) and in the concentration of carbonate ions (so-called ocean acidification). Of growing concern are the impacts that this will have on marine and estuarine organisms and ecosystems. Marine shelled molluscs, which colonized a large latitudinal gradient and can be found from intertidal to deep-sea habitats, are economically and ecologically important species providing essential ecosystem services including habitat structure for benthic organisms, water purification and a food source for other organisms. The effects of ocean acidification on the growth and shell production by juvenile and adult shelled molluscs are variable among species and even within the same species, precluding the drawing of a general picture. This is, however, not the case for pteropods, with all species tested so far, being negatively impacted by ocean acidification. The blood of shelled molluscs may exhibit lower pH with consequences for several physiological processes (e.g. respiration, excretion, etc.) and, in some cases, increased mortality in the long term. While fertilization may remain unaffected by elevated pCO 2 , embryonic and larval development will be highly sensitive with important reductions in size and decreased survival of larvae, increases in the number of abnormal larvae and an increase in the developmental time.
