Juvenile rockfish show resilience to CO₂-acidification and hypoxia across multiple biological scales.

ABSTRACT: California's coastal ecosystems are forecasted to undergo shifting ocean conditions due to climate change, some of which may negatively impact recreational and commercial fish populations. To understand if fish populations have the capacity to respond to multiple stressors, it is critical to examine interactive effects across multiple biological scales, from cellular metabolism to species interactions. This study examined the effects of CO₂-acidification and hypoxia on two naturally co-occurring species, juvenile rockfish (genus Sebastes) and a known predator, cabezon (Scorpaenichthys marmoratus). Fishes were exposed to two PCO₂ levels at two dissolved oxygen (DO) levels: ~600 (ambient) and ~1600 (high) μatm PCO₂ and 8.0 (normoxi
