Sinusoidal swimming in fishes: the role of season, density of large zooplankton, fish length, time of the day, weather condition and solar radiation

Original language description

The sinusoidal swimming of fish was studied in Římov Reservoir, Czech Republic, using a bottom-mounted transducer. The proportion of sinusoidally swimming fish increased from April to August while this behaviour was absent in October. The majority of records came from fish of standard length 100 - 400 mm, which represents the typical size range of common bream and roach of age >1+, the main zooplanktivores in the reservoir. The presence of these larger fish in the open water, as well as the presence ofsinusoidal swimming, correlates with the presence of large zooplankton (Daphnia, Leptodora) in the epilimnion. The increase of sinusoidal swimming between April, June and August resulted in an increase of zooplankton component in fish guts. High values of solar radiation and stable calm weather result in optimal optical conditions for sinusoidal swimming, making this foraging behaviour more efficient and widely used in fishes exploiting the zooplankton production in the reservoir.
