I dont know about the OC southern wrecks but we were out between A and B bouy this saturday in search of Threshers and it was just totally void of any life. We drifted over 6 miles of the prime BSB areas and had some bottom rigs down while sharkin and nothing at all. Came back in and tried Site 10 for some flounder and NADA there either. Never marked a fish all day on my sounder.
Water temps were lower this weekend than 2 weekends ago at 53 to 54 degrees and current was rippin. 16 ounces needed to hold bottom.
