%X Artisanal shark fisheries have been an important source of food and employment in Mexico for many years. In the Gulf of Mexico, this multispecific fishery is based on the seasonal abundance of several shark and teleost species. To obtain fishery and biological information needed to manage the fishery and conserve shark stocks, intensive monitoring of artisanal shark landings was undertaken from November 1993 to December 1994. The State of Campeche had the highest landings and effort. October 1994 had the highest monthly catch per unit effort for all species and areas combined (27.2 sharks per trip). Rhizoprionodon terraenovae (46%), Sphyrna tiburo (15%), and Carcharhinus limbatus (11%) accounted for most of the landings numerically, and the highest catch per unit effort for C. limbatus occurred late in the year as a result of increased landings attributable to an annual southward migration from USA to Mexican waters. The high proportion of neonate and juvenile sharks in gill-net catches from shallow coastal waters suggests that the main shark nursery areas are under heavy fishing pressure. In light of the heavy exploitation of shark resources, the Mexican National Fisheries Institute recommends a number of precautionary actions to avoid the collapse of this fishery. Resumen. Las pesquer&#237;as artesanales de tiburones han sido una importante fuente de alimento y empleo en M&#233;xico durante muchos a&ntilde;os. En el Golfo de M&#233;xico, esta pesquer&#237;a multiespec&#237;fica est&aacute; basada en la abundancia estacional de diversas especies de tiburones y peces. Para obtener la informaci&oacute;n biol&oacute;gico-pesquera necesaria para manejar la pesquer&#237;a y conservar los stocks de tiburones, se realiz&oacute; un monitoreo de las capturas artesanales de tibur&oacute;n entre noviembre de 1993 y diciembre de 1994. Campeche present&oacute; las mayores capturas y esfuerzo. En octubre de 1994 se registraron las mayores CPUE para todas las especies y &aacute;reas combinadas (27.2 tiburones por viaje). Rhizoprionodon terraenovae (46%), Sphyrna tiburo (15%) y Carcharhinus limbatus (11%) constituyeron la mayor&#237;a de las capturas num&#233;ricamente y las mayores CPUE para C. limbatus se produjeron hacia finales de a&ntilde;o a consecuencia del aumento de las capturas atribuible a una migraci&oacute;n anual norte-sur desde los E.U. hacia aguas mexicanas. La alta proporci&oacute;n de neonatos y juveniles capturados en redes agalleras en aguas costeras someras sugiere que las principales &aacute;reas de crianza est&aacute;n sometidas a una alta presi&oacute;n de pesca. En vista de los niveles de explotaci&oacute;n el INP recomienda diversas medidas precautorias para evitar el colapso de la pesquer&#237;a.
