Coral reefs, the “rainforest of the sea,” are a hub of biodiversity. This shark week, let’s uncover the fascinating connection between sharks and coral reefs and the potential of technology and citizen science projects for marine conservation.
Ecosystem health. Sharks, as the guardians of the sea, play a unique role in maintaining the health of coral reefs. Their presence indicates a well-functioning ecosystem, supporting services such as nutrient cycling, water quality maintenance, and habitat structure. By cleaning out dominating species and preying on the weak, sick, or older individuals of prey species, sharks ensure that only the fittest survive, contributing to the overall health of the reef ecosystem. Coral reefs, covering less than one percent of the ocean floor but supporting 25 percent of all marine species, provide shark habitats and nursery areas, especially for juveniles. The complex structure of reefs offers protection and abundant food sources.
Coral reefs act as natural barriers, protecting shorelines from erosion and storm surges. Healthy shark populations indirectly protect reefs and deter overfishing and harmful fishing practices that damage coral reefs. Coral reefs also hold cultural significance for many coastal communities, providing aesthetic, resources and spiritual value for coastal people in tropical environments.
The economic benefits of healthy shark populations and coral reefs are significant. Coral reefs, worth billions of dollars annually between revenue from tourism and fisheries, attract tourists who want to see vibrant marine life. Sharks add to this attraction as part of this vibrant marine life, creating a synergistic benefit for eco-tourism. Regulated shark fisheries, though controversial, can contribute to the local economy. However, they must be balanced with conservation efforts to ensure the long-term economic benefits of healthy marine ecosystems.
Economic losses can result from degrading shark populations and coral reefs, such as declining tourism and fishing yields. Primarily driven by human activities, coral reefs face numerous threats, from climate change and pollution to overfishing and coastal development. Coastal cities must invest in conservation to ensure the long-term economic benefits of healthy marine ecosystems.
Technology. Emerging technologies and research are providing new hope for coral reef restoration. Coral gardening is the process of growing coral fragments in nurseries and then transplanting them onto damaged reefs to help regenerate coral populations. Biorock technology produces natural building materials in the sea. The materials are only marine construction materials that grow and get stronger with age and are self-repairing. It uses low-voltage electrical current to stimulate calcium carbonate deposition, promoting coral growth.
All hands on deck. Citizen science initiatives play a crucial role in coral reef conservation by involving the public in research and monitoring. Many nonprofit organizations help communicate the importance of marine protected areas and assist fishermen in complying with Marine Life Protection Act regulations. Local communities involved in conservation efforts foster a sense of stewardship and raise awareness about reef and shark issues. The University of Miami’s program, Rescue a Reef, is a citizen science project designed to support coral reef research and restoration activities to restore local coral populations on Miami’s coral reefs. UM researchers lead them and provide a unique hands-on educational experience for recreational divers and snorkelers to participate in coral restoration efforts.
