dc.description.abstract No-take marine reserves or no-take zones (NTZ) have become an effective tool for restoring marine populations threatened by overfishing by allowing populations to recover from excessive extraction. In 2004, a NTZ was established within the Mona Island Natural Reserve. The objective of this study is to evaluate the effectiveness of the Mona Island NTZ with respect to coral reef fish populations threatened by overfishing. We used a before-after-control-impact (BACI) design to analyze these effects. Fish abundance and biomass of selected species known to be fishery targets were used as indicators of NTZ effect. Belt transects and roving surveys were used to quantify fish abundances and sizes. Permutational multivariate analyses of variance (PERMANOVA) and SIMPER analysis were carried out to assess spatio-temporal changes between 2005/06 and 2009/10. Significant increases in fish abundance and biomass were observed, suggesting a NTZ effect for important fishery resources. en_US
dc.description.abstract Reservas marinas o zonas de no pesca (ZNP) han llegado a ser una herramienta efectiva para la restauración de poblaciones marinas amenazadas por la sobrepesca. En 2004 se estableció una ZNP dentro de la Reserva Natural de Isla de Mona. El objetivo de este estudio es evaluar la efectividad de la ZNP para proteger poblaciones de peces de arrecife amenazados por la sobrepesca. Se utilizó un diseño antes-después-control-impacto (ADCI) para analizar tales efectos. La abundancia y biomasa de especies conocidas por ser objetivos pesqueros, fueron utilizadas como indicadores del efecto de la ZNP. Transectos de banda y búsquedas aleatorias se utilizaron para cuantificar las abundancias y tamaños de los peces. Se utilizó un análisis de varianza multivariado por permutaciones (PERMANOVA) y análisis de SIMPER para evaluar los cambios temporales entre 2005/06 y 2009/10, y diferencias espaciales entre zona de pesca y ZNP en Isla de Mona. Se observó un incremento significativo en la abundancia y biomasa de peces, sugiriendo un efecto importante de la ZNP para los recursos pesqueros. en_US
