Abstract

The quantity of food in the complete digestive tract of young-of-the-year yellow perch Perca flavescens varied between samples taken at the same time of the day over 2-3 consecutive days, resulting in a 1.7- to 2.5-fold variation of in situ estimates of daily ration. Increased food intake rates were related to increased consumption of large prey items suggesting a day-to-day pattern in the quantity and size of food consumed.
