Survey on Amphibian Pet Trade in Huadiwan Market in Guangzhou

We conducted a market survey on amphibian pet trade in Huadiwan, Guangzhou from 2012 to 2016 in order to investigate the amount of market trade and provided the basic data for further same study. We carried out frequentative investigations (27 times) on market trade and recorded a total of 44 turtle species across two orders, 16 families, 35 genera including two Ambystomatidae species, six Salamandridae species, one Bombinatoridae species, three Bufonidae species, five Ceratophryidae species, four Dendrobatidae species, five Hylidae species, one Hyperoliidae species, two Megophryidae species, six Microhylidae species, one Pelodryadidae species, one Phyllomedusidae species, one Pipidae species, one Pyxicephalidae species, two Ranidae species and three Rhacophoridae species through market review and conservations with peddlers. There were 29 alien amphibian species were sold at this market and these species took a larger proportion (65.91%) than the native amphibians (15 species with 34.09%). Of those amphibians sold in the market, 26 species were listed as protected species. Amphibians around the world are suffered from market trade, which was one of the main factors that causes the decline or extinction of amphibian population, details see Table 1. The survey demonstrated the imperative to improve the wildlife protection law and regulation, emphasized the importance of the prevention of invasive species, as well as analyzed the pressure on ecological system, the influences on species diversity and scientific research of amphibians around the world that caused by the amphibian pet trade.
