Full-Day Coral Propagation Workshop

Coral reefs are among the most diverse ecosystems on Earth, boasting a higher concentration of species per unit area than any other marine environment. However, coral reefs worldwide are facing a severe decline due to both natural and human-induced causes. One potential solution to address this issue is coral propagation, which involves aiding in the reproduction of coral. Ocean Quests' Coral Propagation Program (CPP) is guided by the principle of rebuilding damaged reefs, rather than creating new reefs where they did not previously exist. The program utilizes only live rocks and broken coral fragments sourced from the reefs themselves to rehabilitate them, avoiding the use of unnatural materials such as plastic or cement. Ocean Quest's experienced instructors and divemasters have received training in the Coral Propagation Program, and actively participate in coral propagation initiatives aimed at promoting the growth and recovery of local reefs that have been damaged.
