“…Some local populations of T. liratum experience sharp fluctuations in salinity (>20 psu; Table 1) in a year, and this also suggests its high potential to tolerate decreases in salinity. Similar tolerance to decreased salinity has been reported in bivalve species inhabiting shallow seas and estuaries: Mytella charruana (Yuan et al 2010), Macoma balthica (Jansen et al 2009), Austrovenus stutchburyi, Paphies australis (McLeod & Wing 2008), and Corbula gibba (Holmes & Miller 2006).…”

“…In an intertidal habitat in the Ariake Sea, the environmental salinity decreases at various rates: from 31 to 1 psu seasonally (Table 1); from >25 psu to <5 psu within a day (Fisheries Research Agency & Saga University 2012); and presumably from ≈30 psu to ≈0 psu within several hours owing to rain. Mytella charruana, an estuarine bivalve species, are also found to survive well, regardless of the rates of salinity decreases (Yuan et al 2010): its survival rates were >90%, 5 d after salinity had been decreased either gradually or rapidly from 10-31 psu to 5 psu.…”

Abstract:Laboratory experiments were conducted to examine how the bivalve Trapezium liratum, originating from a population in the Ariake Sea, responds to decreases in salinity in cold and warm waters. After the ambient salinity had been decreased from ≈34 psu to 0-27 psu, 90 to 96% of the specimens survived for >120 h at both 12 and 24°C. When the ambient salinity was decreased to <5 psu the specimens continued to close their valves for 140 h at both temperatures. The percentages of specimens closing their valves, together with clearance and respiration rates, were in general lower for specimens with the ambient salinity more sharply decreased, regardless of water temperature. These results suggest that T. liratum can tolerate a rapid decrease in salinity by closing their valves to decrease water intake.

“…A wider salinity tolerance was also seen for S. cylindraceus when gradually increased/decreased to test conditions (Nel et al, 2011). Numerous studies have illustrated an increase in the salinity tolerance of bivalve species when slowly adjusted to test salinities (Yuan et al, 2010). Additionally, the historical fluctuations observed within False …”

During drought periods, the razor clam Solen cylindraceus is the dominant bivalve in the St Lucia estuarine system, although restricted to its South Lake region. However, with the recent onset of a wet phase, the mussel Brachidontes virgiliae has become widespread and overwhelmingly dominant throughout the system. The salinity tolerance of B. virgiliae is here determined using both rapid and gradual changes in salinity. Mussels were collected at Esengeni in the Narrows (salinity ≈ 0) and Lister's Point in False Bay (salinity ≈ 20). Mortalities were recorded for animals exposed to a sudden change in salinity using 8 different treatments, ranging from 0 to 70. Additionally, animals were exposed to a gradual change in salinity, using treatments that exceeded the minimum and maximum salinities mussels were previously able to tolerate. In all four experiments, animals were able to tolerate salinity levels up to 20. However, a wider salinity tolerance, up to 50, was shown by animals collected from Lister's Point and those gradually acclimated to test conditions. With an increase in flood events predicted for this region, it is imperative to understand how key species may be affected. During wet phases B. virgiliae becomes ubiquitious throughout Lake St Lucia and it is unlikely that the species will disappear from the system, even if floods escalate in the future, as it has an ability to withstand near-freshwater conditions. During dry periods, however, the mussel will be concentrated in the Narrows (oligohaline to limnetic conditions), especially if an inverse salinity gradient with hypersaline conditions prevails within the system.
