摘要: Abstract Management and Exploitation Areas for Benthic Resources (MEABR) is the most common type of coastal marine protected area in Chile, being used managing inshore benthic resources since 1991. The structure biological community MEARBs are poorly studied it though that a better understanding this framework key to sustainability. Here we present food web model characterize functional groups MEABR San Vicente Bay (36°44′S–73°09′W), using Ecopath with Ecosim software (EwE). Chilean albalone Concholepas concholepas main fishing resource many MEABRs, including Bay. structuring role predators assessed compared mixed trophic impacts (MTI) analysis through calculate an interaction strength (IS) index. results show flows consumption occur lower levels (TL ≤ 2), while higher (TL ≤ 3) related mainly C. concholepas. MTI IS C. concholepas crabs whose changes biomass caused greatest change total system can be characterized as playing important ecological roles places. resulted direct indirect have potential affecting sustainability other MEABRs. Future research should also aim at advancing knowledge on basic parameters exploited communities beyond target species.
