A marine mammal stock (a) for which the level of direct human-caused mortality exceeds the potential biological removal level potential biological removal level
The maximum number of animals, not including natural mortalities, that may be removed from a marine mammal stock while allowing that stock to reach or maintain its optimum sustainable population. The potential biological removal level is the product of the following factors: (a) the minimum population estimate of the stock; (b) one-half the maximum theoretical or estimated net productivity rate of the stock at a small population size; and (c) a recovery factor of between 0.1 and 1.0. [defined under MMPA Section 3(20)]
