摘要
The economic performance of Benthic Resource Management Areas (BRMA%26apos;s) was assessed and analyzed for the Bio-Bio region between 2001 and 2003. This study included 22 areas with Use Agreements declaring Toco%26apos; (Concholepas concholepas) to be the main benthic resource. Several characteristics were also considered as potential determinant factors for BRMA performance. These variables were defined and grouped into four types of characteristics: economic, environmental-biological, institutional-organizational, and organizational leader. The variables were then contrasted between areas according to the loco harvest situation. Moreover, the economic performance profiles of BRMA%26apos;s with loco harvests were analyzed according to the considered variables. The results indicate, beyond the different environmental-biological aspects, important differences in economic and institutional-organizational characteristics between areas with and without loco harvests during the period analyzed. Moreover, we conclude that some key variables are associated with economic performance in the areas that harvested loco during the study period, including economic (selling price) and environmental-biological (resource density, habitable polygon) variables Se evalu車 y analiz車 el desempe o econ車mico de 芍reas de Manejo de Recursos Bent車nicos (BRMA) de la regi車n del B赤o-B赤o durante el per赤odo 2001-2003. Con tal prop車sito, se consider車 un total de 22 芍reas con Convenio de Uso que declararon como especie principal el recurso bent車nico loco (Concholepas concholepas). El an芍lisis del desempe o econ車mico de las BRMA%26apos;s considera la exploraci車n de diversas caracter赤sticas como potenciales factores determinantes del referido desempe o. Espec赤ficamente, se definieron variables agrupadas en cuatro tipos de caracter赤sticas para cada 芍rea: econ車micas, ambientales-biol車gicas, institucionales-organizacionales y caracter赤sticas del dirigente. Las variables fueron comparadas entre las 芍reas de acuerdo a la situaci車n de cosecha de loco. Se realiz車 tambi谷n un an芍lisis del perfil del desempe o econ車mico de BRMA%26apos;s con cosecha del recurso seg迆n las variables consideradas. Los resultados indican que, m芍s all芍 de diferencias en los aspectos ambientales biol車gicos, existen diferencias significativas en variables econ車micas, y de caracter赤sticas institucionales-organizacionales entre 芍reas con y sin cosecha de loco durante el periodo analizado. Adicionalmente, se concluye que existen variables claves asociadas al desempe o econ車mico de las 芍reas que cosechan el recurso en el periodo; entre otras, aquellas econ車mic
