The effect of temperature and salinity on the physiological rates of the mussel Perna perna (Linnaeus 1758)

Abstract

ABSTRACT

Interactive effects of temperature and salinity on shell formation and general condition in Baltic Sea Mytilus edulis and Arctica islandica

“…Any departure from optimal salinity conditions (24 in M. edulis; Kossak 2006) requires osmoregulation (regulation of intracellular ion concentrations and organic osmolytes, especially free amino acids; Silva & Wright 1994, Deaton 2001, Kube et al 2006). This can require energy allocation away from antioxidant defence and cellular repair mechanisms, and may cause a further increase in metabolic rate, both mechanisms increasing lipofuscin accumulation (Resgalla et al 2007). The up-regulation of intracellular or ganic osmolytes in response to increasing salinity can consist of breaking down of endogenous proteins, dietary assimilation, de novo synthesis, or uptake from the external media (Hawkins & Hilbish 1992, Deaton 2001.…”

The effect of seasonal temperature variation on behaviour and metabolism in the freshwater mussel (Unio tumidus)

“…Thus, the compensation of oxygen consumption occurred immediately upon temperature change and not as a result of acclimation. Data from other marine and freshwater bivalves such as Perna perna (Resgalla et al, 2007) , Dreissena polymorpha (Alexander and McMahon, 2004), Amblema sp. (Baker and Hornbach, 2001), clearly indicate that oxygen consumption can be partially compensated following acclimation/acclimatization to intermediate temperatures, but not to extreme temperatures.…”

“…In general, oxygen consumption in a range of marine and freshwater bivalves exhibits no thermal compensation at low to intermediate temperatures and only minimal evidence of compensation at intermediate to high temperatures characteristic of their natural thermal range (Alexander and McMahon, 2004;Baker and Hornbach, 2001;Hornbach et al, 1983;Huebner, 1982;Newell et al, 1977;Newell and Pye, 1970;Pernet et al, 2007Pernet et al, , 2008Resgalla et al, 2007;Riascos et al, 2012;Tankersley and Dimock, 1993;Widdows, 1973).…”

Bioaccumulation and persistence of faecal bacterial and viral indicators in Mytilus edulis and Crassostrea gigas

“…exhibited inhibition at extreme salinities of 15 and 40 ppt 19 . In this study, the clearance rate of E. coli, faecal coliforms, intestinal enterococci, somatic coliphage, F-RNA coliphages and bacteriophages infecting B. fragilis GB124 in mussels and oysters after 96 hrs exposure period varied.…”
