Taiwan Joins International Effort to Conserve Critically Endangered Guitarfish

Taiwan has taken a significant step in marine conservation by participating in its first international collaborative effort to protect the critically endangered Bowmouth Guitarfish. This initiative represents a new milestone for research and conservation within the Pacific region.

The Bowmouth Guitarfish is one of the world's most threatened cartilaginous fish, classified as critically endangered (CR) by the International Union for Conservation of Nature (IUCN). Its population decline is attributed to habitat degradation, bycatch in fisheries, and demand for international trade. The species is also listed on Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

The wild ecological data for the Bowmouth Guitarfish is still quite limited. The greatest value of this tagging and release will be to understand its survival status, activity range, and habitat utilization patterns in the wild through scientific tracking technology.

Researchers from the National Kaohsiung University of Science and Technology (NKUST), commissioned by Taiwan's Fisheries Agency, conducted the satellite tagging and release of one Bowmouth Guitarfish off the coast of Taitung on June 22. The fish was confirmed to be healthy and stable before the satellite tracker was attached and it was released back into the wild.

Using ultrasonic tagging and satellite telemetry, the research team aims to collect crucial data on the fish's migratory paths, habitat utilization, and ecological patterns in the Northwest Pacific. This information will serve as a vital scientific basis for evaluating the effectiveness of conservation strategies and informing future management measures for this vulnerable species. The project underscores Taiwan's commitment to international cooperation in safeguarding endangered marine life.

Future research findings can serve as an important basis for evaluating ex-situ conservation strategies and help domestic and international conservation agencies develop more comprehensive conservation management measures.
