Suppose that blue sheep are the most important prey of snow leopard, and that the predator‒prey interaction follows Lotka‒Volterra dynamics. The mortality rate of snow leopard in the absence of blue sheep is 0.1 per week, and the intrinsic growth rate of blue sheep in the absence of snow leopard predation is 0.2 per week. Snow leopard capture efficiency is 0.002, and the efficiency at which blue sheep biomass is converted into snow leopard biomass is 0.2. If there are initially 30 snow leopards and 400 blue sheep, the overall rate of change in the blue sheep population will be a gain of ____ per week.
