maximum extent practicable
(5) (A) For any stock in which incidental mortality and serious injury from commercial fisheries exceeds the potential biological removal level established under section 1386 of this title , the plan shall include measures the Secretary expects will reduce, within 6 months of the plan’s implementation, such mortality and serious injury to a level below the potential biological removal level. (B) For any stock in which human-caused mortality and serious injury exceeds the potential biological removal level, other than a stock to which subparagraph (A) applies, the plan shall include measures the Secretary expects will reduce, to the maximum extent practicable within 6 months of the plan’s implementation, the incidental mortality and serious injury by such commercial fisheries from that stock. For purposes of this subparagraph, the term “maximum extent practicable” means to the lowest level that is feasible for such fisheries within the 6-month period.
