shown in filters: Publications We quantified the diet of Agonostomus monticola during the wet and dry seasons of 1990 in a 15 km reach of the Río Ayuquila, a Pacific tributary of
west-central México. The species consumed 32 animal and 9 plant families, with aquatic insects (mainly Diptera, Ephemeroptera, and Trichoptera) and algae (mainly
Chlorophyta) as primary prey. Animal material dominated the diet in the wet season but was only slightly more important than plant material in the dry season.
Animal material increased in importance with fish size for specimens 151-300 mm total length. [ eng ] |
