you should look at what time of day that most people fish & what they are fishing with.try using something different &down size your baits.if you can fish at night or just before daylight try a buzz bait or zara spook. if during the day try drop shotting with a small weight light wire hook & rubber worm.
try night fishing or fishing on weekdays when its not normally crowded. the fish get used to a pattern of boats going over them and wont eat until night
