Dungeness crab is a valuable species throughout the national marine sanctuaries of the West Coast from Washington state to throughout California. This communication toolkit is designed for educators and communicators to use to teach others about the impact of ocean acidification on Dungeness crab.
The toolkit includes: fact sheet; infographic; PowerPoint slideshow with script; reference list; resource list; public domain video B-roll; and public domain images.
Research suggests that Dungeness crabs are sensitive to the increasing acidity of our ocean. This NOAA Fisheries research will help answer the question of how ocean acidification affects Dungeness crab and will inform strategies to sustain this robust fishery.
This document provides a list of websites and other resources related to Dungeness crab and ocean acidification.

What is ocean acidification? And how could it affect the future of Dungeness crab, one of our favorite seafoods? Join us as we walk through a new national marine sanctuaries educational toolkit to equip you for teaching others about what ocean acidification could mean for the Dungeness crab, how this is currently being investigated, and resources to get more involved.
