On Thursday, The Arizona Game and Fish Commission approved 12 amendments to fish regulations.  The changes are expected to conserve sport fish populations and simplify and streamline regulations. One amendment of particular benefit to anglers is a change in the statewide possession limit to twice the daily bag limit, applying to all statewide and special regulation seasons. The regulation will now give the angler the ability to continue fishing on subsequent days when bag limits are met. The amendments will take effect Jan. 1, 2014.
