INTRODUCTION In 1982, the International Whaling Commission (IWC)

In 1982, the International Whaling Commission (IWC)
decided to impose a moratorium or pause in commercial
whaling. As part of the `Comprehensive Assessment' that
was part of that decision, the IWC's Scientific Committee
began the process of developing a procedure for setting safe
catch limits for commercial whaling for baleen whales
(Donovan, 1989). The agreed objectives for what was to
become the `Revised Management Procedure (RMP)' were:
(i) stability of catch limits which would be desirable for the
orderly development of the whaling industry; (ii) acceptable
risk that a stock not to be depleted (at a certain level of
probability) below some chosen level (e.g. fraction of
carrying capacity), so that the risk of extinction is not
seriously increased by exploitation; (iii) making possible the
highest possible continuing yield from the stock (IWC,
1992a). In this context, the term `continuing yield' refers to
the mean (maximum) yearly harvest in the long term, i.e.
when the exploited stock has reached a stationary state. This
note considers whether the current simulated management
