The mean weight of food items from winter flounder (Pseudopleuronectes americanus) at St. Margaretˈs Bay, Nova Scotia closely coincided with the mean weight of benthic prey potentially available. Flounder larger than the mean length (29 cm) ate heavier particles. Small particles were consistently disregarded. There were seasonal changes in the weights of food items used and in the proportion of organisms to detritus in stomachs.
