Food intake of Macrobrachium rosenbergii during larval development

This work investigates the acceptance of different food types and sizes by Macrobrachium rosenbergii during each larval stage. Food intake of dry and wet formulated diets of four different size classes (250-425, 425-710, 710-1000 and 1000-1190 mum), as well as Artemia nauplii, was determined. Larvae of each zoeal stage were stocked in beakers and fed ad libitum. After 30-45 min, the digestive tract of each larva was observed under a stereomicroscope. Acceptance was evaluated by food intake frequency (FFI). There was no significant interaction (P
