WebFeb 18, 2009 · Biologists stocked a lake with 400 fish and estimated the carrying capacity (the maximal population for the fish of that species in that lake) to be 7200. The number of fish doubled in the first year. a) Assuming that the size of the fish population satisfies the logistic equation: dP/dt=kP (1-P/K) determine the constant k, and then solve the ... WebTo find the appropriate value of C, we need more information, such as an initial condition, the value of P at a certain time t, often (but not necessarily) at t = 0. In particular, if P ( 0) = 0, it turns out that C = M. The limit as t → ∞ is easy to find even if we are not given an initial condition. I assume that the constant k is positive.
