Seawater carbonate chemistry and standard metabolic rate, clearance rate, survivorship and growth of Argopecten irradians

In this study, juvenile northern bay scallops Argopecten irradians (Lamarck) that had been reared since 4 h post-fertilization under one of 2 OA conditions (~500–600 or ~750–850 μatm pCO2; ~1.37–1.5 or ~1.0–1.2 Ωaragonite), were subjected to 2 food levels for 42 d (low food: ~400, high food: ~1400 chlorophyll cells ml–1). Standard metabolic rate (SMR) and clearance rate (CR) were measured on Day 0, and SMR, CR, growth, and survivorship were measured at 14 and 42 days of exposure to 2 food levels for each of the OA treatments.
