    Description: En la actualidad, los programas de mercaje son necesarios para estudios de vital importancia en la biología de poblaciones, como los patrones de migración; ya que es un hecho aceptado desde hace casi un siglo que los peces pelágicos especialmente los clupeideos presentan un ciclo migratorio anual, lo que se manifiesta en la pesquería como cambios espaciales y temporales en las zonas de pesca, con las respectivas oscilaciones en la magnitud de sus capturas. Las técnicas de marcación también permiten evaluar la extensión de la distribución geográfica de una población, los patrones de migración, el número total de individuos de una población, sus parámetros de crecimiento y estim aciones de mortalidad.
    Description: Currently, programs are needed to mercaje critical studies in population biology, such as ”migration patterns” as it is an accepted fact for almost a century that pelagic fishes especially clupeideos present a migration cycle annually, which is manifested in the fishery as spatial and temporal changes in fishing areas, with the respective fluctuations in the magnitude of their catch. Marking techniques also to assess the extent of the geographical distribution of a population, migration patterns, the total number of individuals in a population, their growth parameters and mortality estimates.
