Ramirez, John Ministerio de Agricultura y Desarrollo Rural (Colombia) Global Environment Facility Lane snapper Colombian Caribbean Artisanal fishery Length at first maturity Selectivity Pargo rayado Caribe colombiano Pesca artesanal Talla de primera madurez Selectividad 10 pages, 5 figures, 5 tables [EN] Fishery management measures based on knowledge of fish reproductive biology involve estimation of indicators like length at first maturity, Lm. This indicator, as the case is for length-based indicators, is attractive due to its easy of calculation, in particular, in settings where sophisticated fishery assessment is not in place. On the basis of data originated in the artisanal fishery (2008-2014) estimation was made of length at first maturity of the lane snapper Lutjanus synagris in the Colombian Caribbean and the existence or not of spatial patterns in this indicator was investigated. Tests via resampling showed that length at first maturity vary significantly among regions in range of 16.9 cm to 28.9 cm, total length. Differences in gear (handlines and longlines, gillnets) regional size selectivity correlate with the Lm observed spatial pattern. It is hypothesised that fishing has gone so far as to alter the demography of Lutjanus synagris along the coast in terms of a feedback loop and concomitantly, has altered its length at first maturity, at least as perceived from the fishery data. A plea is made as to redefine management objectives, practice and research needs for the Colombian Caribbean artisanal fishery in view of new paradigm shifts proposals regarding life-history effects of selective fishing on the species concerned [ES] Medidas de manejo pesquero basadas en conocimiento de la biología reproductiva de los peces incluyen la estimación de indicadores como la talla de primera madurez, Lm. Este indicador, como en general los indicadores basados en tallas, es atractivo por su fácil implementación, en particular, en escenarios donde aún no se cuenta con evaluaciones pesqueras sofisticadas. A partir de datos originados en la pesquería artesanal (2008-2014) se estimó la talla de primera madurez del pargo rayado Lutjanus synagris en la costa Caribe de Colombia y se buscó establecer la existencia o no de variación espacial en este indicador. Tests vía remuestreo mostraron que la talla de primera madurez varía significativamente entre regiones con un rango de 16.9 cm a 28.9 cm de longitud total. Dicha variación espacial correlaciono con características de selección de tallas de las artes usadas regionalmente (líneas de mano, palangres y redes agalleras). Se hipotetiza que en términos de un circulo de retroalimentación la pesquería ha alterado lademografía de Lutjanus synagris a lo largo de la costa y en consecuencia su talla de primera madurez, al menos según se percibe de los datos pesqueros. Se hace un llamado en el sentido de reformular los objetivos de manejo, la práctica y las necesidades de investigación en relación a la pesquería artesanal del Caribe colombiano en vista de propuestas de cambio de paradigma en relación a efectos de la pesca selectiva sobre rasgos de la historia de vida de las especies afectada Collection of data by ECOSFERA was supported by project 2008T6540, Ministry of Agriculture, Colombia.
