Artisanal fisheries in a mining concession: a study of ecosystem services

Sylvatrop Consulting was mandated to define and quantify the ecosystem services provided by artisanal fisheries located in a mining concession.

This study analyzed through a 3-week field survey:

  • the different fishing activities and the types of pirogues used: foot fishing, salan, gbankegnyi, flimbotes, yolis …
  • the fishing gear used: encircling gillnet, drift gillnet, set gillnet, longline… 
  • frequented fishing areas : identification of fishing areas, coastal fishing, offshore fishing…
  • fish landings : analysis of captured species (35), classification of species according to the IUCN Red List, numbers, size, weight, sexual maturity, demographic structures of captures…
  • trade and revenue generation: conservation process, sales, prices charged, number of jobs, evolution compared to 2011… 
  • assessment of the impacts of the mining project on the fishing sector and the species present in the marine ecosystems concerned.

In conclusion, this study proposed an approach for maintaining this priority ecosystem service.
