I am not sure about license since it has been almost thirty years since I have fished while on the rock. But I can share this little fishing tale. After a few years of travel and staying up in the hills we would make are daily 45 min. walk down to the beach. And each time I would notice as I crossed the bridge over the Negril River all these fish swimming around. So before are next trip my friend and I decided to bring fishing poles and some crank baits for trolling. When we arrived we talked a friend who had a small fishing boat to take us fishing up the Negril River. We started trolling just beyond the bridge, catching all different types of fish, and I could tell you what kind most where. The only ones I knew the speices were the Snook that we caught and kept to eat. I can tell you though it was lots of fun, and some very beautiful scenery back in the Morrass.
