Blacktail shiners, Notropis venustus, were collected in Bayou Sara, West Feliciana Parish, Louisiana, every three hours over a 24-hour period on two different days (12-13 April 27-28 June, 1975) to determine feeding chronology and food habits of this species. Peak feeding activity was just prior to sunset. Feeding was sporadic at night, lowest just prior to sunrise, and increased steadily after sunrise. Notropis venustus is predominantly carnivorous. Terrestrial insects were the major food items. Feeding activity appeared to be a function of the availability of food organisms.
