Amendment 14 established the permit stacking program, which allowed up to three tier permits to be placed on a vessel and for the vessel to fish up to the combined limits for all three permits. It also authorized extension of the season (once the Congressional moratorium on catch share programs was lifted). Amendment 14 was implemented August 7, 2001, and the primary fishery ran from August 15 to October 31. Beginning in 2002, the fishery was able to run for its full intended length (April 1 through October 31).
