SITUACIÓN DE Menidia jordani (Pisces: Atherinopsidae) EN EL EMBALSE LA GOLETA, ESTADO DE MÉXICO.

Abstract

En este estudio se analiza la situación del charal Menidia jordani (Pisces, Atherinopsidae) en el embalse La Goleta, Estado de México y las variaciones poblacionales desde 1998, cuando se registró por primera vez en el embalse. Para ello se realizaron visitas en 1998, 2007 y 2008 durante las épocas secas y de lluvias. Los peces fueron capturados con un chinchorro charalero de 30.0 m de largo, 1.5 m de caída y 8.0 mm de abertura de malla, fijados con formalina al 10 %, llevados al laboratorio e identificados. Los resultados muestran que la mayor abundancia de M. jordani se registró en 1998 (3,000 peces·1000 m-2), mientras que la menor abundancia se presentó en 2008 (5 orgs.·1000 m-2). Se concluye que estas variaciones están en función de la presencia de especies exóticas como la carpa común (Cyprinus carpio) y la carpa dorada (Carassius auratus), con las cuales compite, asimismo, la presencia de una especie carnívora (Micropterus salmoides) afecta la población del charal en el embalse. El céstodo (Bothriocephalus acheilognathi), influyó en la disminución de este pez y el vertido de aguas negras hacia este sistema afectaron también su abundancia.
