Abstract
Planktonic predator-prey interactions in homogeneous isotropic turbulence are studied by a series of numerical experiments and the effects on the ingestion rate of turbulence mixing and predator's ability are closely investigated. Particular attention is paid to the question how the simulation results are affected by taking account of the relative distance between predator and prey in deciding whether the prey have been consumed during the prey-predator contact. The numerical experiment shows that the optimal foraging strategy depends on the range of predator's detection of prey.
