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

Abstract: 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 … Show more

“…For example, Gray et al (2019) estimated native Olympia oysters to filter 28% of Yaquina Bay, OR within a single residence time after accounting for hydrodynamics. This estimate is substantially larger than that of an earlier study (1% per residence time) by zu Ermgassen et al (2013) who used a much simpler method when accounting for hydrodynamics (tidal prism method), which likely underestimated the residence time of the ecosystem (Lemagie and Lerczak 2015). Aside from residence time, the frequency at which a parcel of water was exposed to filterfeeding activity of oysters before exiting the estuary, termed encounter rate by Gray et al (2019), was also considered to be important when estimating oyster FS but was not quantified.…”

“…The Olympia oyster ( Ostrea lurida , Carpenter 1864) is a native estuarine bivalve found from Baja California to the central coast of Canada, patchily distributed over strong environmental gradients (Chan et al, 2017; Schoch et al, 2006). Oysters are ecosystem engineers in estuaries, providing structured habitat and removing suspended sediments (zu Ermgassen et al, 2013; Coen et al, 2011). Unlike other oysters where both males and females spawn gametes (e.g., Crassostrea ), the females fertilize eggs with sperm from the water column and initially brood larvae in the mantle cavity.…”

“…Even within species, there can be substantial differences in ecosystem service delivery between geographies, as evidenced by the regional differences in fish and mobile invertebrate production from C. virginica reefs in the Gulf of Mexico relative to the South and Mid‐Atlantic USA (zu Ermgassen, Grabowski, Gair, & Powers, 2016). The environmental setting can also play a critical role in the degree of service delivery; for example, oysters are unlikely to have played as important a role in water quality on the Pacific coast of the USA relative to the Atlantic coast, not only because the native species of oyster, O. lurida , has slower clearance rates, but also because Pacific coast estuaries tend to have lower residence times (zu Ermgassen, Gray, Langdon, Spalding, & Brumbaugh, 2013). As such, there is a strong case for building a greater quantitative knowledge for each species, despite having confidence that certain ecosystem services are likely to arise from universal ecosystem engineering properties.…”
