Strait of Georgia and Howe Sound Glass Sponge Reef

To protect glass sponge reefs, which are slow growing and fragile.

All forms of bottom-contact fishing are prohibited.

Glass sponge reefs are presently found only along the west coast of Canada and the United States. They play an important role in ecosystems by modifying bottom currents, filtering water, and creating habitats for other species. Ecologically important species of finfish and shellfish, such as rockfish and spot prawns, rely on glass sponge reefs for refuge from predators and for breeding.
