Download our full-resolution, printable version: More about the OA in Canada Species Impacts Series: To summarize the current knowledge of OA impacts on species in Canada, the OA CoP has produced a poster series on how species are impacted by OA in Canada. The information presented here is based on the most current scientific literature (peer-reviewed, published papers) of studies conducted in Canada. We also highlight current gaps in our knowledge and areas that require additional research across Canada. These infographics are intended not only to highlight concerning OA impacts on important species in Canada, but are also meant to act as catalysts to support filling the gaps in our knowledge of OA impacts to species across Canada. Poster Text: OA in Canada Species Impacts: pink salmon Fast Facts: Scientific name: Oncorhynchus gorbuscha Range: Pacific and Arctic Canada Lifestyle: anadromous (spawn freshwater, adults live in ocean), eats herring, small invertebrates Smallest, most common Pacific salmon species Salmon in general represent 89% ($866M) of aquaculture values in Canada1 and 20% ($889M) of all seafood industries in Canada2 OA Impacts in Canada (table): Overall Calcification Growth Survival/ Abundance Reproduction Physiological Larval ▼ ? ▼ ? N/A ▼ Juvenile Mixed (▼ - NE) ? No Effect No Effect N/A Mixed (▼ - NE) Adult ? ? ? ? ? ? Only 2 OA studies 3,4 on salmon conducted in Canada Of the 6 species in Canada, pink salmon are the only salmon species with OA studies in Canada In general, early life stages of pink salmon appear fairly resilient to OA 3, but with some negative impacts to larval stage 4 Current Gaps: OA impacts to adult life stages? OA impacts to other salmon species in Canada? Uncertainties on OA impacts to early life stages?

Happy Halloween! Here are some of the latest happenings in the world of ocean acidification in Canada and beyond! Paper of Interest: Check out this new Canadian paper! Frommel, A. Y., Lye, S. L., Brauner, C. J., & Hunt, B. P. (2022). Air exposure moderates ocean acidification effects during embryonic development of intertidally spawning fish. Scientific Reports, 12(1). https://doi.org/10.1038/s41598-022-16399-6 The GOA-ON Monthly Webinar Series is back: The goals of the GOA-ON Webinar Series are to enable members to share their science with the broader community, create opportunities for collaboration, and foster a sense of community among GOA-ON members. This amazing webinar series is back starting in November. Click here to see the GOA-ON website for more information. New OA Podcast: The latest episode of the podcast The Irish Tech News centers around ocean acidification! The following is quoted text: In this podcast Melanie Boylan chats with Manuel Bustelo and Alana Alvarez Vernice about their ongoing mission to highlight ocean acidification. Listen in to find out how you can help to make everyday changes to improve our planet's oceans. To listen to the podcast click here! 5th International Symposium The Effects of Climate Change on the World’s Oceans: Call for abstracts and financial support applications is open until 1 November 2022! ​​​ECCWO5 (Bergen Norway, 17-21 April 2023) brings together experts from around the world to better understand climate effects on ocean ecosystems, what adaptation and mitigation measures could look like, and how to implement them​. The symposium is continuing the successful series of ECCWO symposia over the last few years. Click here to submit an abstract to ECCWO5! The OA CoP at the 5TH INTERNATIONAL SYMPOSIUM ON THE OCEAN IN A HIGH CO2 WORLD: All presentations from this conference have temporarily been posted on the Symposium High CO2-Lima YouTube channel here. These videos will be featured on the channel until November 25th, don't miss out! The Canadian OA CoP attended this symposium and select side meetings. We gave an oral presentation about the activities of the OA CoP, how we formed, and the current projects we are undertaking. The conference was full of other wonderful presentations, posters, and plenaries (which can be seen on the High CO2 YouTube channel here). At the symposium, we attended the official GOA-ON side meeting: OCEAN ACIDIFICATION GOA-ON REGIONAL HUB COORDINATION WORKSHOP. In this meeting, we saw updates from all the GOA-ON Hubs and had the opportunity to discuss all of the wonderful resources that are offered through this organization. We encourage all of our members to join whichever GOA-ON Regional Hubs which is most relevant to them (Canada is included in both the North American Hub and the Arctic Hub). To learn more about GOA-ON please visit their website by clicking here! We also attended the side meeting: FROM KNOWLEDGE TO ACTION: COMMUNICATING OA SCIENCE TO POLICY MAKERS run by the OA Alliance and Ocean Foundation. This meeting saw discussions between international participants with the goal of identifying major steps that can be taken at the science-policy interface. To guide these discussions this workshop featured presentations from experts in the field, such as Jessie Turner Director of the OA Alliance, who gave insights into how this organization delivers projects on the science-policy interface. To learn more about these organizations we encourage you to visit the website for the OA Alliance here and the Ocean Foundation here.
