The Lump, which is the top of a large salt dome, is located approximately 50 miles southwest off the coast of Venice, Louisiana and is legendary for great bluewater fishing. The combination of shallower waters (depth ranges between 200 and 250 ft.) and the large schools of bait fish that get caught in the current is what makes fishing on the Lump great. It is a major feeding sight for some of the largest yellowfin tuna found in the Gulf of Mexico.
Fishing on the Midnight Lump is at its finest beginning in late December through the month of March. Tuna and wahoo are caught in abundance by live baiting and chumming from an anchored boat while out on the Lump. Marlin can also be caught while Lump fishing. Since the Lump is located in federal waters bag limits are strictly enforced.
