“…In M. galloprovincialis , heatwave exposure above 27°C was also reported to be associated with an increased mortality risk (Olabarrial et al, 2016). Conflicting results were reported for the effect of an increased number of aerial thermal stresses, with studies showing an increased mortality risk in M. edulis (Jones et al, 2009; Jones et al, 2010), a decreased mortality risk when the mussels had previously been exposed to chronic chemical contamination (Peden et al, 2018) or no effect in M. galloprovincialis (Dowd & Somero, 2013). In M. galloprovincialis , the thermal range between air and water temperature exposures showed inconsistent effects on the mortality risk between the laboratory studies (Schneider, 2008; Anestis et al, 2010; Dowd & Somero, 2013), probably because of the heterogeneity of the ranges investigated, varying from 2 to 20°C.…”

“…Another study reported the effect of hypoxia‐induced stress on mussel mortality to be size‐specific, with larger mussels having an increased mortality risk under hypoxia conditions than smaller ones (Altieri & Witman, 2006). Gradual acclimation of the mussels to warmer temperatures modulated the effect on M. edulis mortality of the combined exposure of mussels to chronic chemical contamination and acute heat stress (Peden et al, 2018). The effect of the initial farming density on the mortality risk was modulated by mussel size, with mortality of small seed generally increasing with increasing initial density, while mortality of large seed was not affected by initial farming density (Lauzon‐Guay et al, 2005).…”

The aim of this study was to summarise the literature reporting the risk factors for mortality in the mussel species Mytilus edulis and Mytilus galloprovincialis in order to identify potential science-based solutions to prevent or mitigate mussel mortality outbreaks. We followed the PRISMA methodology: Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The studied corpus of 91 publications (114 studies) was highly heterogeneous with respect to the methodological approaches used to define or estimate mussel mortality and the related putative risk factors. Results showed that the mortality risk of both mussel species M. edulis and M. galloprovincialis varied across the seasons, increased with an elevated seawater temperature above a thermal threshold of 20 and 24°C, respectively, decreased by protecting mussels from predation, and was associated with the presence of pathogens in M. edulis. For M. galloprovincialis, using mussel spat from the same area where the farming is carried out and farming them together with another mussel species appears to reduce the mortality risk. However, for M. edulis, this could be achieved by using pure crosses and in particular mussel spat having a selected genotype. For wild bed conservation, sand accumulation and anthropogenic sedimentation should be minimised. Our analysis showed that current approaches to this research topic are limited and are unlikely to yield actionable evidence to identify mussel mortality prevention or mitigation strategies. Therefore, recommendations are offered to increase the ability of future eco-epidemiological research to identify multiple exposures associated with mussel mortality, underpinned by standardised efforts and cooperative initiatives.

Aquaculture production as an important source of protein for our diet is sure to continue in the coming years. However, marine pollution will also likely give rise to serious problems for the food safety of molluscs. Seafood is widely recognized for its high nutritional value in our diet, leading to major health benefits. However, the threat of marine pollution including heavy metals, persistent organic pollutants and other emerging pollutants is of ever-growing importance and seafood safety may not be guaranteed. New approaches for the search of biomarkers would help us to monitor pollutants and move towards a more global point of view; protocols for the aquaculture industry would also be improved. Rapid and accurate detection of food safety problems in bivalves could be carried out easily by protein biomarkers. Hence, proteomic technologies could be considered as a useful tool for the discovery of protein biomarkers as a first step to improve the protocols of seafood safety. It has been demonstrated that marine pollutants are altering the bivalve proteome, affecting many biological processes and molecular functions. The main response mechanism of bivalves in a polluted marine environment is based on the antioxidant defense system against oxidative stress. All these proteomic data provided from the literature suggest that alterations in oxidative stress due to marine pollution are closely linked to robust and confident biomarkers for seafood safety.

“…In ecotoxicology, 2DE has been widely used to study Mytilus species responses to various stresses including temperature, mainly in M. galloprovincialis, M. californianus or M. trossulus (Tomanek and Zuzow, 2010;Ji et al, 2013;Gomes et al, 2014;Xu et al, 2016) but also in M. edulis (Apraiz et al, 2006;Sheehan and McDonagh, 2008;Letendre et al, 2011;Hu et al, 2014;Péden et al, 2016;Péden et al, 2018). We thus conducted a 2DE proteomic analysis of gills collected from mussels maintained at 7.5°C and 20°C.…”
