ASAHI, Minoru (Mukogawa Women's Univ., Nishinomiya) A method for calculation of each re-trapping rate in the marking-and-recapturing. Jap. J. Ecol. 14,116-119 (1964). Many investigators have pointed that the first trapping rate (p) is not equal to the re-trapping one (π). Here, π includes the second time rate (p_2), the third one (p_3) and so on, however, when p (≡p_1)≠π, it is considered that p_2≠p_3≠…. A model is given to find each re-trapping rate. If we define N_<n-1> as the subpopulation of i-times trapped animals after the n-times inspection, the total population is shown by that [numerical formula]. And it is easily recognized that [numerical formula] etc, can be revealed from the records and N_<n+o> may be estimated along with N, for which many formulae have been proposed. Here, we put [numerical formula] and [numerical formula] for p_i (i>1). And for p_1,some estimation methods are already proposed. A sample of calculation on this method is shown additionally.
