Bushmeat and Fish

The consumption of bushmeat in West Africa is in part driven by declining fish stocks. The EU fishing fleet has increased its catch off West Africa by a factor of 20 between 1950 and 2001, while also receiving increasing subsidies from the EU. The West African commercial fishing fleet has also increased considerable.

See the remarkable paper Bushmeat Hunting, Wildlife Declines, and Fish Supply in West Africa, by: Brashares, Justin S., Arcese, Peter, Sam, Moses K., Coppolillo, Peter B., Sinclair, A. R. E., Balmford, Andrew, Science, 00368075, 11/12/2004, Vol. 306, Issue 5699. It can be found here (subscription necesary).

The multibillion-dollar trade in bushmeat is among the most immediate threats to the persistence of tropical vertebrates, but our understanding of its underlying drivers and effects on human welfare is limited by a lack of empirical data. We used 30 years of data from Ghana to link mammal declines to the bushmeat trade and to spatial and temporal changes in the availability of fish. We show that years of poor fish supply coincided with increased hunting in nature reserves and sharp declines in biomass of 41 wildlife species. Local market data provide evidence of a direct link between fish supply and subsequent bushmeat demand in villages and show bushmeat’s role as a dietary staple in the region. Our results emphasize the urgent need to develop cheap protein alternatives to bushmeat and to improve fisheries management by foreign and domestic fleets to avert extinctions of tropical wildlife.
