How It WorksThe shell-filled structures act as artificial reefs, creating habitat for fish, invertebrates and other marine species to colonize. Unlike traditional concrete or metal reef structures, the shells provide a natural surface that encourages biological growth. Five Test Sites Across BCSThe state has installed five pilot reef sites at varying depths, from five meters to 80 meters, each serving a different purpose. Officials say the goal is to integrate local fishing communities directly into the program so they understand the benefits and eventually take ownership of the system. “The objective is to integrate the fishing communities so they themselves adopt the model,” Rodríguez explained.
