Details	Catchability and multiple uncertainties associated with invasive species are newly incorporated into the mathematical model for analyzing optimal management strategies. In particular, we focus on stock-dependent catchability, growth uncertainty and measurement uncertainty, each of which is a critical factor that influences invasive species management. By incorporating these factors into the analysis, we successfully derived some important policy implications in relation to invasive species management in the way that the results becomes more practical and implementable in reality.
