ABSTRACT With the purpose of evaluating the status of the lane snapper Lutjanus synagris from limited catch length data from the landings of artisanal fishing catches recorded between 2006 and 2012 in Tayrona and Corales del Rosario y de San Bernardo National Parks, and the Vía Parque Isla de Salamanca, simple indicators and the decision tree methodology were applied. it was observed that this indicator mostly configured a selectivity pattern represented in capture of mayoritary immature specimens (<L mat ) and a spawning biomass level lower than the target reference point, affecting the natural renewal of L. synagris stocks. Also, it was ratified the degree of overfishing for growth and recruitment to which L. synagris is subjected. Reducing pressure on snapper resource is a management objective that requires greater protection in the three protected areas for their ability to export the resource, as well as participatory regional fisheries management for the sustainability of the resource. Therefore, it is recommended to reach conservation agreements that promote responsible fishing of mature fish. This objective will allow maximum biomass yield, and better economic income for fishers. We also propose to apply the methodology described in this study to evaluate other fishery resources caught in the protected areas.
