Abstract
La sistemática de los bagres marinos pertenecientes a la familia Ariidae es controversial, porque hasta la actualidad,
no se conoce con exactitud el número de especies y géneros existentes en la familia, ni las relaciones que se establecen
entre ellos. En el presente trabajo se estudiaron las relaciones filogenéticas entre cinco especies representativas
de bagres marinos de la familia Ariidae, de ambas costas del Pacífico y del Atlántico Mexicano. El mencionado análisis
se llevó a cabo mediante el análisis de la variabilidad en 21 loci aloenzimáticos y a través de la comparación de patrones
electroforéticos de proteínas totales de músculo. Los niveles de divergencia interespecífica obtenidos por ambos
métodos electroforéticos mostraron una clara separación entre los géneros Cathorops, Bagre y Ariopsis, así como
entre las especies estudiadas de Cathorops y Ariopsis con Bagre marinus, mostrando una mayor similitud genética con
el grupo Ariopsis. Los resultados obtenidos en este estudio contribuyen al establecimiento de la presencia de estas
especies a lo largo de las costas del Golfo de México.
The systematics of the marine catfish of the family Ariidae is controversial because at the present time the number of species and genera in the family, or their relationships, remain uncertain. Phylogenetic relationships among five representative species of marine catfish of the family Ariidae from both the Pacific and the Atlantic coasts of Mexico were assessed by the analysis of the variability in 21 alloenzymatic loci, and by the comparison of the electrophoretic patterns of whole muscle proteins. Interspecific genetic divergence levels obtained by both electrophoretic methods showed a clear separation among the genera Cathorops, Bagre and Ariopsis, as well as in the studied species of Cathorops and Ariopsis, with Bagre marinus showing a greater genetic similarity with the Ariopsis group. Finally, our results contribute to the definition of the presence of this species in the coasts of the Gulf of Mexico
