Abstract

This study investigated the effects of hypoxia on the behavior and physiology of juvenile rockfishes in a controlled laboratory setting to test how deoxygenation may impact early life stages of common temperate reef fishes. Juvenile rockfishes were collected from shallow 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 reared in the labora...

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. These data are published in Mattiasen et al. (2020).
