Diel feeding periodicity in larvae of the vendace ( Coregonus albula L.) and influence of food availability and environmental factors on food intake
Abstract— Samples were taken every 2 h for 10 days to determine diel foraging periodicity of vendace larvae in the littoral zone of Lake Lentua, northern Finland and to assess environmental factors affecting food intake. Feeding was associated with daylight conditions, so feeding ceased in the dark....
