Fry of striped bass (Morone saxatilis) 9 to 19 days old remained active and continued to feed at night. We observed no significant difference in egestion time between fish held in light and those held in darkness. At 20°C the gastrointestinal tracts of all 15- and 19-day-old fish were emptied of marked brine shrimp in 11-12 h. None of the 9-day-old fish held at 25°C contained marked brine shrimp after 9 h.
