Investigating mitigation for sediment acidification in Burrard Inlet, BC, Canada to support First Nation shellfish managment
Shellfish are an important ecological, economic, and cultural component of the Pacific Northwest (PNW). Shellfish provide critical ecosystem services, and the PNW shellfish aquaculture industry is growing, contributing to the economy and global food security. Shellfish have been a staple in the trad...

Shellfish are an important ecological, economic, and cultural component of the Pacific Northwest (PNW). Shellfish provide critical ecosystem services, and the PNW shellfish aquaculture industry is growing, contributing to the economy and global food security. Shellfish have been a staple in the traditional diet and subsistence economy of coastal First Nations for thousands of years. Harvesting shellfish also provides a means of cultural transmission and cross-generational teachings. Ocean acidification threatens sensitive coastal and estuarine ecosystems. Calcifying organisms, such as bivalve shellfish, which inhabit these ecosystems, are particularly vulnerable to acidification as they require carbonate to produce their shells. Sediment acidification poses a potential threat to these important coastal species. Sediment conditions (e.g. porewater pH) may have disproportionate effects on shellfish growth and survival, compared to the overlying water column.
