AbstractThe effects of predicted levels of elevated CO2 in marine waters on invertebrates and fish species is an increasing concern. Numerous studies have found significant physiological and behavioral effects in fish induced by elevated CO2 exposures, including our earlier study that demonstrated olfactory injury from elevated CO2 in coho salmon (Oncorhynchus kisutch) that was associated with interference of gamma-aminobutyric acid (GABA) signaling in the salmon olfactory bulb. However, the effects of elevated CO2 may be species-specific, and there have been few studies addressing the effects of elevated CO2 on benthic fish. In the current study, we investigated the effects of elevated CO2 exposures on the deep-water benthic dwelling species, sablefish (Anoplopoma fimbria). Sablefish were exposed to three different levels of CO2 (700, 1600 and 2700μatm) for two weeks, followed by behavioral, neurophysiological and gene expression analysis of the central olfactory system.
