Local perceptions, hunting and export of the Endangered Goliath frog Conraua goliath in Cameroon

Abstract

AbstractOfficial protection of an exploited species sometimes precedes any quantitative understanding of its use, including any dependence of local residents on it for food and livelihood. Conservation initiatives could suffer without this information. The Goliath frog Conraua goliath is iconic globally because of its large size, and is categorized as Endangered on the IUCN Red List. The main threat to this species in Cameroon is overexploitation, but any associated socio-economic aspects of this have not been quantified. We provide insights into local perceptions of the Goliath frog and its consumption through structured interviews with 223 people living alongside this species. The Goliath frog is well known and hunted both for home consumption and the wild meat trade. We trailed seven collaborative Cameroonian Goliath frog hunters over two seasons to determine offtake. A total of 192 Goliath frogs were collected by these hunters, peaking in March. The hunters used nets, shotguns and spears. Their catch was eaten at home or sold fresh within the community or to travellers for XAF 1,500–5,000 (USD 3–10) each. We also studied the Goliath frog trade by examining the databases of the Cameroonian Ministry of Forestry and Wildlife, and CITES. CITES and hunters reported large exports of Goliath frogs but no trade was documented by the Ministry of Forestry and Wildlife. To support conservation planning, this study provides preliminary quantitative information on the extent of the threat of hunting to this Endangered frog.
