Shrimp is the most important marine resource for the three communities of the Upper Gulf of California (UGC): San Felipe in the state of Baja California, and Golfo de Santa Clara and Puerto Peñasco in the state of Sonora. This fishery generates 80% of the profits in the region. A fishery tendency analysis was made from 1996 to 2007 in the UGC. For the first time, this fishery analysis showed that the Biosphere Reserve and the recently declared Vaquita Refuge Area are important grounds for artisanal fishing. The CPUE and total catches used to describe the fishing effort in the area, could be used to establish any further relationship between shrimp population and environmental variables, because of their high correlation coefficient (0.85). Shrimp capture in the marine protected areas has maintained a continuous level of production with economic incentives, making it attractive to fishermen despite recent restrictions on their activities. As shrimp vessels reduce in number, small boats gradually increase in number and productivity, maintaining high incomes from the fishery. A detailed interdisciplinary study of the fishing effort in the UGC must be conducted, because of the endangered species found in this area, which require adequate management for their conservation without compromising the welfare of the fishermen. El camarón es el recurso pesquero más importante en el Alto Golfo de California (AGC) para las tres comunidades pesqueras que en ella se encuentran: San Felipe, Baja California, Golfo de Santa Clara y Puerto Peñasco, Sonora. Esta pesquería por si sola genera el 80% de los ingresos pesqueros totales en la región. Se hizo un análisis de la tendencia de la pesca de camarón del periodo 1996 al 2007. Por primera vez se describe la importancia de la pesca dentro de la Reserva de la biosfera del Alto Golfo de California y del Refugio de la Vaquita Marina. Debido al alto coeficiente de correlación (0,85), la captura total y el CPUE analizados para el esfuerzo pesquero pueden ser utilizados para establecer futuras relaciones entre las variables ambientales y la población de camarón en la región. La captura del camarón mantiene un continuo crecimiento en las áreas naturales protegidas (ANP) siendo atractivo para los pescadores a pesar de las recientes restricciones a la pesca. Al disminuir el esfuerzo de las embarcaciones mayores dentro las ANP, se ha incrementado gradualmente la productividad de las embarcaciones artesanales, lo que ha propiciado un aumentando en el numero de embarcaciones y de los ingresos económicos en la región, manteniéndose una alta rentabilidad de la pesquería. El esfuerzo pesquero realizado por pescadores de las comunidades en el AGC dentro de las ANP requiere de un estudio más complejo e interdisciplinario, ya que en esta ANP se encuentran especies en peligro de extinción, el cual requieren de un manejo adecuado para su conservación sin que afecte los intereses individuales de los pescadores.
