N.J. Stat. Ann. § 23:3-1b

The Division of Fish, Game and Wildlife, after consultation with the Fish and Game Council, shall select two days in any given 12-month period, and consecutively thereafter, during which any person who has an actual and bona fide domicile in this State may fish in any of the waters of this State without procuring the license required pursuant to R.S. 23:3-1 et seq. or the special trout stamp required pursuant to the provisions of P.L. 1952, c. 328 (C. 23:3-57), except if the Commissioner of the Department of Environmental Protection determines that emergency conditions exist during any given 12-month period which make "free fishing" days ill-advised.
