Depends on where you were fishing on the jetty. You don't need one on a jetty per fish and game regulations, however, the definition of a jetty is rocks having water on
both sides. The way the Wedge jetty is built there is rock rip-rap on the harbor side from the last house on Channel until the actual "jetty" starts where you have ocean on one side and harbor on the other side.

So you have about 275 yards of rocks (as measured using google maps ruler tool) on the harbor side that are not covered under the legal definition of jetty and you would need a license there.
