  • Abstract en Traps and poison bait are used to control invasive species and protect native species. However, the traps can kill native species and the poison bait may increase their mortality. As it interferes with conservation efforts, it is necessary to evaluate the effects of such bycatch. However, there are few theoretical methods for quantification of these effects. This paper presents a method for quantitatively evaluating the effects of bycatch on native populations, using a mathematical model that represents the population dynamics of native and invasive species. The mathematical model suggested the conditions under which only invasive species will be eliminated even if bycatch occurs. We also present the concept of the ”bycatch curve”, which shows the population density according to the killing rate. In addition, a mathematical simulation is presented using parameters estimated for the Amami-Oshima system. These theoretical results allowed us to determine the parameters that should be prioritized for estimation in actual control programs.
