  ABSTRACT: One error was found in the coding of the simulation program for reproducing the recruitment (R) and spawning stock biomass (SSB) of Pacific bluefin tuna. As a result of this error, the maturity rates for ages 3 and 4 were found to be much lower in the simulation than the true values. The aim of this paper is to show the results when the error is corrected. The R and SSB were under-estimated in response to the error. As a result, the natural mortality coefficients (M) in the previous paper were assumed to be smaller so that the reproduced R and SSB would coincide with those observed. When the error was corrected, it was not necessary to assume the value of M to be smaller. When the corrected progam and the original M values were used, the R and SSB reproduced in the simulation coincided well with those shown in the previous paper.
