Manta Ray Welfare and Gill Raker Trade

Manta rays are hunted primarily for their gill rakers, sold in Asian traditional medicine markets. This trade causes significant welfare harm to individual animals and threatens species survival.

Key Facts

Manta rays are targeted for their gill rakers, used in traditional Chinese medicine despite no proven health benefits.
Both giant manta ray and reef manta ray species are now listed as Vulnerable on the IUCN Red List.
Manta rays reproduce slowly — females bear only one pup every 2-5 years — making populations vulnerable to hunting pressure.
Capture methods including harpoons, nets, and drive fisheries cause significant pain and prolonged death.
Many countries and international agreements now protect manta rays; trade through CITES Appendix II is regulated.
Manta ray tourism generates substantially more revenue per animal alive than through the gill raker trade.

Welfare Considerations

Manta rays are among the most charismatic and intelligent marine animals — with the largest brain-to-body ratio of any fish and evidence of self-awareness. Their capture and killing for a traditional medicine ingredient with no scientific basis is a profound welfare and conservation failure. Capture causes acute stress, physical injury, and often slow death. Conservation efforts that protect manta rays are also welfare interventions: ending the gill raker trade eliminates enormous suffering for individual animals while preserving populations that are irreplaceable ecologically and economically through tourism.

What You Can Do

Never purchase traditional medicine products containing manta ray gill rakers.
Support manta ray conservation organizations working on trade reduction and legal protection.
Choose manta ray tourism operators with responsible swimming guidelines that minimize disturbance.
Advocate for stronger enforcement of CITES manta ray trade protections.
Share information about the lack of medicinal benefit and high welfare cost of the gill raker trade.
