Data from experiments testing the effects of hypoxia on behavior and physiology of two species of rockfish from from 2015-2016

<p>Juvenile rockfishes were collected from shallow (~10-20 m depth) rocky reef and kelp forest habitats at Stillwater Cove, central California (36˚ 34' N, 121˚ 56' W) during May-June of 2015. Newly settled copper (Sebastes caurinus) and blue (Sebastes mystinus) rockfish were collected weekly using large mesh hand nets while SCUBA diving. Fishes were measured for length and weight and tagged using Visual Implant Elastomer Tags. Juvenile rockfishes were exposed to one of four treatment levels corresponding to conditions that currently occur or are predicted to occur in the future on the central California coast (Chan et al., 2008; Booth et al., 2012; Fig. 1): 100% saturation (8.74 ± 0.03 mg O2 L-1), 68% saturation (6.00 ± 0.04 mg O2 L-1), 46% saturation (4.06 ± 0.04 mg O2 L-1), or 26% saturation (2.25 ± 0.05 mg O2 L-1), with two replicate tanks per treatment level. Behavior and physiological trials were conducted on each individual, including (1) escape response, (2) behavioral lateralization, (3) standard metabolic rate, (4) maximum metabolic rate, (5) aerobic scope, (6) pCrit (i.e., hypoxia tolerance test), and (7) ventilation rate.
