SPECIES IMPACTS
There are many species in Canada that are vulnerable to ocean acidification. Across the country, research is being conducted to understand how species respond to OA (and other co-stressors, such as changing ocean temperature and oxygen levels), but there are still many unknowns.
Below are resources summarizing our current understanding of how species in Canada are responding to OA. Explore by different biological responses, species, region, or industry (fisheries and aquaculture).
ÉVÉNEMENTS À VENIR ET EN COURS
Overview
-
25% ($1.14B) of species are unstudied in Canada with respect to OA impacts:
-
Queen/snow crab (11% or $500M)
-
Scallops (4% or $196M)
-
Fish (with the exception of 2 studies on pink salmon and 1 on Pacific herring)
-
Unstudied fish species represent 9% or $419M in Canada
-
-
-
49% ($2.21B) are negatively impacted by OA
-
23% ($1.03B) have reported mixed negative effects (negative - no effect)
-
3% ($113M) have mixed responses (negative - no effect - positive)
-
Values are based on Aquaculture and Fisheries values reported by DFO in 2023.
-
Species responses are based on current scientific literature (ADD WHITE PAPER CITATION).
