Foraging patterns of four sympatric species of silversides (Atheriniformes: Atherinopsidae) in Lago de Pátzcuaro, Central Mexico

Abstract: RESUMEN: Los patrones de forrajeo de cuatro especies simpátricas del género Chirostoma (Chirostoma estor, Chirostoma grandocule, Chirostoma attenuatum y Chirostoma patzcuaro) fueron evaluadas en el Lago de Pátzcuaro, para entender la repartición de recursos alimenticios y su coexistencia simpátrica. La abundancia de invertebrados presa fue estimada en distintos hábitat alimenticios y se midieron parámetros físicos y químicos del hábitat en dos sitios de estudio. Los peces fueron recolectados durante las tempor… Show more

“…Our results do not agree with this hypothesis because there were no differences found in the main prey types in the two size‐categories, in accord with the findings of García de León et al. (), but which differed from those of Solórzano (), Rosas (), Rauda (), Moreno (), and Ross et al. ().…”

“…García de León et al. () stated that silversides feed in different habitats (benthos, periphyton, and nekton) of different trophic webs (autochthonous and allochthonous food items). This feeding strategy allows silversides to resist anthropic changes to the habitat: despite dramatic changes to the lake, silversides are currently the dominant taxa (Ramírez‐Herrejón, ).…”

“…(Bradbury, ; Caballero et al., ), facilitating the reproduction of Chirostoma and growth of larvae (Rojas‐Carrillo, ). The deep open areas would support high populations of mature fish (García‐De León, Ramírez‐Herrejón, García‐Ortega, & Hendrickson, ; Soria‐Barreto & Paulo‐Maya, ), promoting the population expansion shown by the Bayesian skyline plot for that period.…”
