Abstract

OLAYA RODRIGUEZ, María H et al. Mapeo del servicio ecosistémico de alimento asociado a la pesca en los humedales interiores de Colombia. Ecol. austral [online]. 2017, vol.27, n.1, suppl.1, pp.123-133. ISSN 1667-782X.

The fishery resource faces great threats worldwide, so it is vital to make an analysis of its dynamics as food and its conservation as an integrated part of the evaluation of an ecosystem service (SE). In the inland wetlands of Colombia, fishing is an activity of cultural and economic importance since about 26% of the national territory is covered by wetlands. This work identifies and maps, from the continental fishing activity, the beneficiaries and the spatial dynamics of the ES of food associated with fishing offered by inland wetlands of Colombia.We describe: i) species richness associated with fishing, ii) areas supplying the ES, iii) areas with the beneficiaries of the ES, iv) fow of the ES, and v) the endangered status of the species within the fishery resource. We identified 138 fsh species were consumed by communities. The Orinoco and Amazon basins were identified as the richest areas of fishery resources species, whereas the Magdalena-Cauca’s basins were identified as the areas with more supply of the ES. On the other hand, several communities in the Andean and Amazonian region were identified as the main direct beneficiaries of ES (self-consumption), while main cities, followed by numerous neighboring municipalities, were identified as areas of indirect beneficiaries (marketing of fishery). Spatialization and visualization of these aspects allowed to analyze the different factors that determine and affect the ES in the country’s wetlands and make suggestions on management actions for the fishery resource.

Keywords : Watersheds; Fishes for consumption; Richness; Supply areas; Areas of beneficiaries; Fows of fishing; Endangered species.
