摘要：
A model representing the predator‐prey interactions between two copepod species, Euterpina acutifrons and Temora stylifera, with unlimited resources was used to study effects of exploitation. Exploitation is modeled by harvesting strategies characterized through three parameters: the selectivity of gear, the frequency of harvest, and the intensity of harvest effort. Simulations of different harvesting strategies suggest that interactions between species influence the dynamic behaviors of the populations as well as harvesting yields.
