SUMMARY
Manta and mobula rays, the mobulids, span the tropics of the world and are among the most captivating and charismatic of marine species. However, their

the increasing demand for their gill plates, which are used as a pseudo-medicinala health tonic in China.
To assess the trade in dried mobulid gill plates (product name ‘Peng Yu Sai’), and its potential impact on populations of these highly vulnerable species, WildAid researchers conducted market surveys throughout Southeast Asia in 2009-10.This research, compiled in our 2011 report The Global Threat to Manta

The observed increase in supply, coupled with evidence of increasing market demand for Peng Yu Sai, suggests that the marketbased threat to manta and mobula populations from Peng Yu Sai consumption is still increasing and even more immediate today.

In Guangzhou, we surveyed the Qingping and Yuexiu markets focusing on Traditional Chinese Medicine (TCM) retailers and dried seafood vendors. Overall, we estimated >1,100 dried seafood and TCM vendors, combined, across both market areas. We visually surveyed 783 stores and stalls for presence/absence of Peng Yu Sai, and systematically inquired about product availability in stores not displaying the product. We found 122 vendors selling dried gill plates. In both 2010 and 2013, the Qingping Lu market area appeared to have the most stores carrying Peng Yu Sai. In 2013, across all Guangzhou markets, we found an apparent consolidation with fewer vendors comprising a larger percentage of the market volume.

A majority of vendors reported a steady increase in demand and a steady or decreasing trend in supply. Our research indicates a marked increase in demand, however, our observations strongly suggest that the vendors’ perceived decrease in supply is a misconception based on possible competition for stock.

and most customers reported purchasing Peng Yu Sai on a monthly basis. The survey’s results further revealed a demographic of Peng Yu Sai consumers comprised primarily of working mothers/wives, over 40 years of age, who are the primary purchasers for their households and who retain traditional living habits of Cantonese, especially cooking soups with different ingredients according to the season and physical condition of the family.ꢿꢦꢢꣀ

STATUS AND TOURISM
Global manta and mobula ray population numbers are currently unknown.(11) However, these species don’t begin reproduction until 8-10 years+ of age, are long-lived at 40 years+, and reproduce slowly; for example, manta rays have a single pup every 2-5 years. Meanwhile, the estimated global landings of these rays, in 2010, were 94,000 mobula rays and 3,400 manta rays.(12) Additionally, “Factors including illegal, underreported, [unregulated] and unrecorded

Several nations and territories now protect some or all mobulid ray species in their territorial waters. However, overall, these protections are likely inadequate to protect these vulnerable species throughout their circumglobal range. For example, legal protections of mobula species are far less common than for manta species, and most of the laws protecting manta rays only apply to one of the two manta species, M. birostris. New protections since the
publication of The Global Threat to Manta and Mobula
