• F I S H R E S P I R AT I O N Food was withheld for 48 h prior to conducting respirometry on fishes to ensure that the Ë™ MO 2 measurements were not influenced by specific dynamic action (SDA; the energy used in the digestion, absorption and assimilation of a meal; Clark et al., 2010; Chabot et al., 2016a). The respirometers were cleaned as detailed above and all recirculation pumps were switched on to assist with clearing air bubbles from the respirometers.

• Hypoxia, or the depletion of oxygen to relatively low concentrations (VaquerSunyer and Duarte, 2008) can occur naturally in aquatic systems. Due to changing climate and continued increasing anthropogenic nutrient loading, the number of hypoxic zones has increased worldwide and will likely continue to increase in the future (Diaz, 2001;Diaz and Rosenberg, 2008;Zhang et al., 2010). Hypoxic zones are most commonly defined by oxygen concentrations that cause lethality (often dissolved oxygen, DO, concentrations < 2.0 mg/L).

• Background respiration was calculated in empty chambers at the beginning of each session and then subtracted the overall oxygen consumption in each chamber. Standard metabolic rate (SMR) was calculated using the 0.10 quantile (Daoud et al., 2007;Dorcas et al., 2004). Differences in SMR, ETS, and CS among treatments for Group B2 lobsters were investigated using 1-way multiple analyses of variance (MANOVA) as they were measured on the same individuals.
