Hunting for bushmeat in the tropics has become a major issue in terms of conservation and human health, especially in western and central Africa. In Cote d'Ivoire, despite a ban on hunting since 1974, the bushmeat trade is widespread. This situation has been exacerbated by the long-term socio-political unrest in Cote d'Ivoire, resulting in the lack of effective protection of protected areas (PAs). Our study was carried out in the central-west Department of Daloa. We conducted standard interviews with the six main traders of the markets to trace the geographical origin of the bushmeat, and quantify the number of animals sold by direct observations twice a week during 52 weeks. We used multiple regression analyses to identify combinations of variables (proportion of animals killed, mean body mass, total biomass, price of carcass, price per body mass) that influenced poaching pressure. A total of 955 carcasses were recorded in the central market of Daloa. This number includes 948 mammals (99 %), six reptiles (0.6 %), and one bird (0.1 %). Rodentia were the most frequently sold taxons by number of individuals (58 %), followed by Artiodactyla (35 %), Carnivora (4 %), and Primates (1 %). Almost half of the game originated from the Department of Zoukougbeu (42 %; N = 404), followed by the Departments of Daloa (29 %; N = 275) and Se ' gue ' la (13 %; N = 123). Over 75 % of all the carcasses appearing in the market consisted of greater cane rats and bushbuck. In contrast, over 68 % of the total biomass (23028.75 kg) entering the market was supplied by Bushbuck and Common warthog. Game diversity by catchment area was the highest in Se ' gue ' la and Gre ' gbeu and the lowest in Guezon and Maminigui. Our data indicated that hunting was unequally distributed throughout the central-western region of Cote d'Ivoire or markets are unequally provisioned by hunters. Human population density of the catchment areas affected the quantity and the quality of bushmeat observed at the urban market. Increasing hunting pressure in the Departments of Zoukougbeu proximate to the Haut Sassandra forest reserve indicates that the local authority in charge of the surveillance of this reserve has to reinforce its protection to avoid further faunal depletion. Because most of the ungulates and rodents found on the market occur at high density in disturbed habitats, their relative frequencies in the carcasses provisioning the market could be used as indicators of site over-exploitation.
