Diel changeover in sandbank fish assemblages in a neotropical floodplain river

  title={Diel changeover in sandbank fish assemblages in a neotropical floodplain river},
  author={D. Albrey Arrington and Kirk O. Winemiller},
Fishes were collected over 7 months (February to June and November to December 1999) from seven sandbanks located on the main channel of the Cinaruco River, Venezuela. Significant shifts in assemblage structure and species richness were documented between diurnal and nocturnal samples. Seine samples standardized for effort yielded 41 604 individual fishes representing seven orders, 25 families, 80 genera and 134 species. Nocturnal samples yielded 68% of the total individuals, and 54% of species… CONTINUE READING
