Sharks, rays, and chimaeras have long been essential to ocean ecosystems, playing critical roles in maintaining marine biodiversity. However, these ancient and vital species are facing an unprecedented crisis. According to the Global Status of Sharks, Rays, and Chimaeras report by the International Union for Conservation of Nature (IUCN), one-third of these species are now threatened with extinction. Compiled by 353 experts from 115 countries, this comprehensive report highlights the urgent need to address overfishing, bycatch, and inadequate conservation measures across the globe.
A Growing Crisis for Marine Species
Since the publication of the IUCN's first report nearly two decades ago, the plight of sharks, rays, and chimaeras has become even more critical. Despite significant strides in research and conservation, their populations continue to decline. Overfishing remains the primary threat, driven by targeted fishing and bycatch. Countries like Indonesia, Spain, and India lead global shark fishing, contributing to massive population losses among species like rhino rays, angel sharks, and wedgefish.
Demand for shark-related products has surged, with the global trade in shark and ray meat now valued at 1.7 times that of the fin trade. Products such as ray gill plates, liver oil, and shark skin contribute nearly USD 1 billion annually to global markets. Across various cultures, sharks are exploited for a range of uses, from traditional medicines to luxury goods. For example, shark liver oil is used in traditional cosmetics in Oman, while stingray skin is fashioned into luxury handbags in Thailand and Europe.
The Role of Sharks in Marine Ecosystems
Sharks, rays, and chimaeras are more than just iconic marine species—they are pivotal to the health of our oceans. Some species act as carbon sinks, aiding in the fight against climate change by preserving carbon-sequestering habitats like mangroves. Others contribute to nutrient cycling, ensuring the resilience of marine ecosystems. In vulnerable coastal communities, shark fisheries are vital for food security, with some fishers reporting that sharks and rays account for over 80% of their income.
Brendon Sing, Founder of Shark Guardian, emphasizes:"Protecting sharks isn’t just about saving a species; it’s about preserving entire marine ecosystems. Sharks are also the foundation of thriving eco-tourism industries, demonstrating their immense value alive, not dead. By safeguarding sharks, we’re also investing in the health of our oceans and the communities that depend on them."
Solutions and Recommendations
Despite the alarming statistics, the IUCN report offers a roadmap for recovery. Country-specific solutions are outlined, focusing on sustainable fisheries management, improved bycatch policies, and stricter trade regulations. Success stories in nations like Canada, the USA, and Australia demonstrate that sustainable practices can work, but these efforts must be replicated globally.
Conservation organizations like Shark Guardian play a vital role in these efforts. Through campaigns like the UK Shark Fin Ban and extensive educational outreach, Shark Guardian works tirelessly to combat the shark fin trade and advocate for stronger protections. Their citizen science projects and shark diving expeditions further support global conservation efforts, highlighting the ecological and economic value of living sharks.
A Global Call to Action from IUCN report
The message from the IUCN report is clear: we cannot afford to delay action. Governments, conservationists, and communities must unite to implement the report’s recommendations, ensuring that sharks, rays, and chimaeras continue to thrive. As Dr. Rima Jabado, IUCN SSC deputy chair, states:"With the precarious state of many of these species, we can’t afford to wait."
