Selección del zooplancton por el charal Chirostoma jordani (Atheriniformes: Atherinidae)

Abstract

Se realizó un estudio para evaluar la selección del zooplancton por el charal Chirostoma jordani en el embalse Trinidad Fabela (19°48'12" - 50'36" N: 99° 46' 23" - 39" W), abarcando las cuatro épocas del año (1983 - 1984). Los peces fueron recolectados con un chinchorro de 8 mm de luz de malla y el zooplancton con una red de 125 micras de at'ertura de malla. La comunidad zooplanctónica está representada por seis géneros de los cuales Diaptomus fue el más abundante durante todo el año. La selección que ejercen los charales recae sobre los géneros Bosmina, Daphnia y Diaptomus. Los charales seleccionan su alimento.

Zooplankton selectivity by the silverside fish Chirostoma jordani, was made in the Trinidad Fabela reserveir, México (19° 48 ' 12"- 50' 36" N; 99° 46' 23" - 39" W) encompassing the four seasons (1983 - 1984). Fish were collected using a dragnet with 8 mm mesh size and zooplankton with a 125 micron mesh size pJankton neto The zooplankton community is represented by six genera among which Diaptomus was the most abundant throughout the year. The silverside select their prey, prefering the genera Bosmina, Daphnia and Diaptomus.
