Electrophoretic variation between the central and southern populations of the northern anchovy Engraulis mordax Girard 1854 (Engraulidae, Pisces) from Baja California, Mexico

Electrophoretic variation between the central and southern populations of the northern anchovy Engraulis mordax Girard 1854 (Engraulidae, Pisces) from Baja California, Mexico

Distinctive genetic markers of the central and southern populations of the northern anchovy Engraulis mordax were sought by electrophoretic techniques. Three samples of the central population were collected in Ensenada, Baja California, and one of the southern population in Puerto San Carlos, Baja C...

Three samples of the central population were collected in Ensenada, Baja California, and one of the southern population in Puerto San Carlos, Baja California Sur. Although the electrophoretic separation of the hemoglobins in polyacrilamide gels were identical in both populations, the FST of the esterases loci showed significant differences between them, and the proteins of the muscle extract as well as the parvalbumins yielded some bands that were exclusive to one population or the other. These bands might prove useful as genetic markers in studies of population dynamics on which the management of this valuable fishery resource can be based. Se identificaron marcadores genéticos distintivos de las poblaciones central y sureña de la anchoveta Engraulis mordax por medio de técnicas electroforéticas. Se realizaron tres recolecciones en Ensenada, Baja California, como muestras de la población central, y una en Puerto San Carlos, Baja California Sur, de la población del sur. Aunque las separaciones electroforéticas en geles de poliacrilamida de las hemoglobinas no mostraron diferencias poblacionales, se encontró que los sistemas de proteínas totales de músculo y las parvalbúminas muestran algunas bandas exclusivas de una u otra población y que el estadístico FST de los loci polimórficos de las esterasas estudiados muestran diferencias estadísticamente significativas. Las diferencias encontradas pueden ser útiles como marcadores genéticos y marcan la pauta para profundizar en los estudios de dinámica de poblaciones, sobre los que se pueden sustentar el manejo de este valioso recurso pesquero.
