I am going out deep sea fishing in about 2 weeks, and was wondering if anyone knows specific techniques for catching big groupers. Last time I went there were some caught but not any big ones. I heard that grouper can see line very well and are shy about biting when they can see it. I read somewhere that if you use flourocarbon that it will entise more strikes. What is the preferred bait for these fish. Any info will be greatly appreciated.
