The consumption of phantom midge Chaoborus flavicans larvae by Perca fluviatilis showed clear response to water colour, predation threat and shoal composition with the most significant negative effect for water colour. In the case of Rutilus rutilus , no similar combined response was observed and the total prey consumption was significantly negatively affected by predation threat of Esox lucius . The results suggest that differences in life‐history traits may result in disparity in species‐specific responses to disturbance.
