The trade of wild meat in urban markets has become a controversial topic because despite the economic returns it can generate for local communities, it can cause a dramatic increase in harvest rates of game species. The trade of wild meat could be a very accessible and low-cost method to monitor the regional game populations. Nevertheless, the wild meat trade is difficult to monitor because this is an illegal activity and vendors often distrust researchers. In this study, we used two long-term monitoring datasets collected in one of the most important and largest open markets in wildlife in the Amazon, in Iquitos (Peru), to estimate the minimum effort required to obtain reliable information on the amount and trends of wild meat trade. Two 12-month surveys were conducted in the Belén Market between September 2006 and August 2007 (2,443 interviews in 182 sampling days), and between September 2017 and August 2018 (2,081 interviews in 138 sampling days). The data submited in page "interviews year-along" includes the price and the amount of total wild meat, and volume (in kg) of meat of Tayassu pecari -white-lipped peccary-, Cuniculus paca -paca-, Pecari tajacu -collared pecari-, and Mazama sp. -brocket deer- sold in each interview day. In October 2018, at the end of the survey of 2017-2018, we conducted an interview directly to the eleven most frequent wild meat sellers in order to obtain their personal perception on the average price and daily amount of wild meat sold year-along. This information is included in the page "Single questionary".
