| Summary: | Under any pooled management scheme, such as the former Blue Whale Unit system for baleen whales, it is impossible, without appropriate technological developments, to attain the theoretical maximum sustainable harvest, that is, the sum of the maximum sustainable yields which single-species theory indicates is possible. Pursuit of this maximum is likely to result in overexploitation and stock failures. In general there can be a variety of alternative targets on a sustained basis.Regulation by area is worthy of consideration as one possible pooled management measure that will improve the sustainable harvest of the resources concerned. A set of the principles for valid area divisions is defined graphically and mathematically, although success depends on how well the proportion of each stock unit in the catch can be controlled by feasible area divisions. |
