“…Even though the results of this study were surprising, with increased growth at ρCO 2 levels predicted for the RCP 6.0 scenario, growth decreased at levels predicted for the RCP 8.5 scenario. Results of an experiment with juveniles of this subspecies indicate a similar hormetic response to that of larvae in our study (Pousse et al, 2020). Pousse et al (2020) found metabolic depression in juvenile Atlantic surfclam exposed to ρCO 2 levels of 1350 µatm, making them more susceptible than Pacific oyster (Lannig et al, 2010) and blue mussel (Thomsen and Melzner, 2010).…”

“…A synthesis of available reports on ecological consequences of ocean and coastal acidification for species in the Northeast U.S. continental shelf large marine ecosystem has identified that to date little is known on how coastal bivalve species will respond to OA (Hare et al, 2016). Recently, juvenile Atlantic surfclam (Spisula solidissima) were found to have modified physiological processes at CO 2 levels of RCP 8.5 scenario during a 12-week exposure, with them being more sensitive than previously studied estuarine bivalves (i.e., oyster species and the blue mussel, Mytilus edulis) to increasing ρCO 2 levels (Pousse et al, 2020). The results of that study highlight the need to understand how larval Atlantic surfclam will respond to OA conditions.…”

“…However, no effects at ρCO 2 concentrations of the RCP 8.5 scenario have been reported for the Olympia oyster (Ostrea lurida) (Waldbusser et al, 2016), Antarctic bivalve (Laternula elliptica) (Bylenga et al, 2015), or blue mussel (Gazeau et al, 2013). A hormetic response to OA exposure in bivalves, although not often reported, was recently reported for juvenile Atlantic surfclam (Pousse et al 2020) and has been noted in other marine species, including copepod (Li and Gao, 2012;Thor and Oliva, 2015) and finfish (Miller et al, 2013(Miller et al, , 2016 species.…”

The Atlantic surfclam (Spisula solidissima) supports a $29.2-million fishery on the northeastern coast of the United States. Increasing global carbon dioxide (CO 2 ) in the atmosphere has resulted in a decrease in ocean pH, known as ocean acidification (OA), in Atlantic surfclam habitat. The effects of OA on larval Atlantic surfclam were investigated for 28 d by using 3 different levels of partial pressure of CO 2 (ρCO 2 ): low (344 µatm), medium (821 µatm), and high (1243 µatm). Samples were taken to examine growth, shell height, time to metamorphosis, survival, and lipid concentration. Larvae exposed to a medium ρCO 2 level had a hormetic response with significantly greater shell height and growth rates and a higher percentage that metamorphosed by day 28 than larvae exposed to the high-and low-level treatments. No significant difference in survival was observed between treatments. Although no significant difference was found in lipid concentration, Atlantic surfclam did have a similar hormetic response for concentrations of phospholipids, sterols, and triacylglycerols and for the ratio of sterols to phospholipids, indicating that larvae may have a homeoviscous adaptation to OA at medium ρCO 2 levels. Our results indicate that larval Atlantic surfclam have some tolerance to slightly elevated ρCO 2 concentrations but that, at high ρCO 2 levels, they may be susceptible to OA.

“…Multiple aspects of the carbonate system have been shown to have impacts on marine biota. Reductions in CO 3 2availability and O a below critical thresholds have been shown to represent a stressor to a variety of shelled marine invertebrates (e.g., Clements et al, 2017Clements et al, , 2018Rheuban et al, 2018;Young and Gobler, 2018;Pousse et al, 2020) including crabs, lobsters, oysters, scallops, and mussels in the GOM (Tables S1 and S2). The pH can impact physiological processes that rely on the transfer of [Hþ], including olfactory senses in fish (e.g., Dixson et al, 2015) and crab megalopae (Miller et al, 2016).…”

“…These projections and the high revenue underscore an urgent need for laboratory and field research on how sea scallops respond to OA and increased water temperature, so that the industry and managers can respond accordingly to maintain sustainable stocks. Similarly, the Atlantic surfclam is another commercially prized species, with ample distribution from Canada's Gulf of St. Lawrence to North Carolina in the United States, that has already shifted northward in its distribution (Timbs et al, 2019), but studies of its response to OA have begun only recently (Pousse et al, 2020;Meseck et al, 2021; Table S1).…”

Ocean acidification (OA) is increasing predictably in the global ocean as rising levels of atmospheric carbon dioxide lead to higher oceanic concentrations of inorganic carbon. The Gulf of Maine (GOM) is a seasonally varying region of confluence for many processes that further affect the carbonate system including freshwater influences and high productivity, particularly near the coast where local processes impart a strong influence. Two main regions within the GOM currently experience carbonate conditions that are suboptimal for many organisms—the nearshore and subsurface deep shelf. OA trends over the past 15 years have been masked in the GOM by recent warming and changes to the regional circulation that locally supply more Gulf Stream waters. The region is home to many commercially important shellfish that are vulnerable to OA conditions, as well as to the human populations whose dependence on shellfish species in the fishery has continued to increase over the past decade. Through a review of the sensitivity of the regional marine ecosystem inhabitants, we identified a critical threshold of 1.5 for the aragonite saturation state (Ωa). A combination of regional high-resolution simulations that include coastal processes were used to project OA conditions for the GOM into 2050. By 2050, the Ωa declines everywhere in the GOM with most pronounced impacts near the coast, in subsurface waters, and associated with freshening. Under the RCP 8.5 projected climate scenario, the entire GOM will experience conditions below the critical Ωa threshold of 1.5 for most of the year by 2050. Despite these declines, the projected warming in the GOM imparts a partial compensatory effect to Ωa by elevating saturation states considerably above what would result from acidification alone and preserving some important fisheries locations, including much of Georges Bank, above the critical threshold.
