“…This result disagreed with most studies that related the body size or biomass with the filtration rates in the zebra mussel (Dreissena polymorpha) (e.g. Bij de Vaate, 1990, Berg et al, 1996) as well as in many bivalves (Bougrier et al, 1995). Such poor association in the case of the golden mussel has also been observed by Sylvester et al (2005), which was statistically significant only at 20ºC.…”

“…for oysters with a DTW of 1 g suggested by Cranford et al (2011); however, it is substantially lower than the rates of 5 l g -1 h -1 (Newell 1988) and 6.79 l g -1 h -1 (Riisgaard 1988) frequently cited for C. virginica, and 4.83 l g -1 h -1 cited for C. gigas (Bougrier et al 1995). While there has been significant interest in developing a generalized model for filtration by bivalve filter feeders (e.g., Powell et al 1992;Cranford et al 2011), which is useful in the absence of species-specific data, it is also clear that differences in FR between species may be substantial (Moehlenberg and Riisgaard 1979;Riisgaard 1988;Powell et al 1992).…”

“…In this case, we used the historic densities and areal extent of O. lurida beds, but applied the FR for C. virginica from zu Ermgassen et al 2012 and C. gigas from Bougrier et al (1995) and assumed a mean oyster SH of 60 mm, which is more reasonable for these larger, faster growing species, falling in the mid-range of 2-year-old C. virginica as reported in Rothschild et al (1994).…”

Quantifying the historic contribution of Olympia oysters to filtration in Pacific Coast (USA) estuaries and the implications for restoration objectives

The Olympia oyster, Ostrea lurida Carpenter, was formerly widespread in many US Pacific coast estuaries. Following dramatic declines in the late 1800s and early 1900s, this species is now the focus of renewed restoration efforts. Restoration is undertaken for brood stock rehabilitation as well as a range of ecosystem services such as filtration; however, these ecosystem services are as yet poorly quantified. We present the first laboratory measurements of filtration rates (FR) for O. lurida, to which we fit a model of FR as a function of dry tissue weight and water temperature. We find that O. lurida has a FR at optimum temperature similar to previously established means across oyster species at 1 g dry tissue weight (DTW), but lower than many Crassostrea species. We also find that the allometric exponent relating FR to DTW in O. lurida is lower than the previously published mean across oyster species. Based on our derived filtration rates and historical data, we estimate the historic impact of filtration by O. lurida in five Pacific coast estuaries. We find that historic O. lurida populations did not have the capacity to filter the full volume of the estuary within the estuary residence time in any of the estuaries examined. This result is primarily driven by the low water temperatures and the short estuary residence times that typify the Pacific coast. We conclude that, unlike Crassostrea virginica Gmelin on the Atlantic and Gulf coasts, the Olympia oyster was not historically a dominant force in regulating seston concentrations at large scales in Pacific coast estuaries. Given the differences in the ecological role and habitat structure of these two oyster species, we recommend that analogies between them be drawn with caution. We discuss the implications of our results for developing restoration objectives.

“…Wang et al (2012) reported synergic effects of heat stress and infection on scallop survival and attributed it to energetic stress. A similar mechanism may have played a role for the oyster mortality, because only heat stress, but not cold stress has been shown to increase energy consumption in Pacific oysters (Bougrier et al, 1995;Malham et al, 2009). Injection of the virulent Vibrio sp.…”

Hemolymph microbiome of Pacific oysters in response to temperature, temperature stress and infection

Microbiota provide their hosts with a range of beneficial services, including defense from external pathogens. However, host-associated microbial communities themselves can act as a source of opportunistic pathogens depending on the environment. Marine poikilotherms and their microbiota are strongly influenced by temperature, but experimental studies exploring how temperature affects the interactions between both parties are rare. To assess the effects of temperature, temperature stress and infection on diversity, composition and dynamics of the hemolymph microbiota of Pacific oysters (Crassostrea gigas), we conducted an experiment in a fully-crossed, three-factorial design, in which the temperature acclimated oysters (8 or 22 1C) were exposed to temperature stress and to experimental challenge with a virulent Vibrio sp. strain. We monitored oyster survival and repeatedly collected hemolymph of dead and alive animals to determine the microbiome composition by 16s rRNA gene amplicon pyrosequencing. We found that the microbial dynamics and composition of communities in healthy animals (including infection survivors) were significantly affected by temperature and temperature stress, but not by infection. The response was mediated by changes in the incidence and abundance of operational taxonomic units (OTUs) and accompanied by little change at higher taxonomic levels, indicating dynamic stability of the hemolymph microbiome. Dead and moribund oysters, on the contrary, displayed signs of community structure disruption, characterized by very low diversity and proliferation of few OTUs. We can therefore link short-term responses of host-associated microbial communities to abiotic and biotic factors and assess the potential feedback between microbiota dynamics and host survival during disease.
