Inconsistent reporting of shark and ray trade data is causing problems for conservation efforts of these vulnerable species, according to a new study.

CITES wants improvements made to the accuracy and comparability of shark and ray trade data, with the hope to establish more effective conservation strategies

The review, “Deep Diving into Shark Catch and Trade Mismatches”, commissioned by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) Secretariat with funding from the EU, builds upon previous work published by Traffic and saw the NGO partner with the CITES Secretariat and Deakin University to undertake the current review.

With over 24% of all shark and ray species are currently threatened with extinction, the report highlights the challenges faced in conserving these vital ocean predators and emphasises the importance of improving the accuracy and comparability of shark and ray trade data, ultimately leading to more effective conservation strategies for these species.

The study found that different countries and organisations use varying units of measurement, leading to discrepancies in reported data. It also identified a lack of clarity on reporting requirements for certain types of catches and inconsistencies in how catches from different territories are reported.

One of the most concerning findings is the widespread underreporting of CITES-listed shark and ray species. This underreporting could be due to a lack of awareness or understanding of reporting obligations, or non-compliance.

The Chinese province of Taiwan, a major player in high-seas fishing, was identified as a significant source of unreported trade, as it does not report to CITES despite reporting to some regional fisheries bodies. This lack of transparency hinders efforts to monitor and regulate the trade effectively.

To address these issues, the study recommends:

  • All parties should report trade data in weight rather than number of specimens
  • Adopting traceability systems
  • Addressing discrepancies in existing databases
  • Developing clearer guidance on reporting requirements
  • Reminding parties of their obligation to submit comprehensive annual reports.

The study also calls for increased collaboration between international organisations to standardise data collection and reporting practices, including reporting all catch with details on its fate, mandating reporting by weight and at the species level, and adopting internationally recognised coding systems.

The CITES Animals Committee adopted all the recommendations from the review. Alongside this, the committee also adopted the Shark working group report with some minor changes.
