The effect of turbidity and illumination on the reaction distance and search time of the marine planktivore Gobiusculus flavescens
Both reduced illumination and increased turbidity caused a significant reduction in reaction distance of Gobiusculus flavescens . The longest reaction distance, 18.9 cm for larger prey (Calanus finmarchicus) , occurred at a light level of 80 μmol m −2 s −1 compared to 12.9 cm for a smaller prey (Aca...
