Effects of OA on Alaskan and Arctic fishes: physiological sensitivity in a changing ecosystem

Why we care
There is significant concern about ocean acidification disrupting marine ecosystems, reducing productivity of important fishery resources, and impacting the communities that rely upon those resources. To predict the ecological and socioeconomic impacts of acidification, it is critical to understand the complex interactions between environmental stressors of physiology and ecology of marine fishes. Previous work on Alaskan groundfish focused on direct physiological effects of OA on early life stages. We need to further this work to understand the interaction between OA and co-stressors like elevated temperatures on fish productivity. 

What we are doing 
This AFSC project examines the interactive effects of OA and elevated temperatures on three fish species that are critical to Alaska and Arctic fisheries: Pacific cod, Arctic cod, and yellowfin sole. Laboratory experiments will track the impact of OA exposure on adult Arctic cod reproductive output, egg quality, and larval production. Further experiments will consider the potential for within-generation and trans-generational acclimation and adaptation to environmental changes. Risk assessments for regional fisheries will incorporate the data from this project.

Benefits of our work
Findings from this research will provide the foundation necessary to evaluate the ecological and socioeconomic impacts of ocean acidification in Alaskan and Arctic waters.

Ocean Acidification: Building a Path Toward Adaptation in the Arctic

Ocean Acidification: Building a Path Toward Adaptation in the Arctic

NOAA Ocean Acidification Program

Scientists, economists, and stakeholders from all eight Arctic countries forge a path forward in adapting to ocean acidification in the Arctic

Arctic waters are rapidly changing. In the coming decades, these high-latitude waters will undergo significant shifts that could affect fish, shellfish, marine mammals, along with the livelihoods and well-being of communities dependent on these resources.
