Just a quick differance. Night time equals fishing the top 300 feet of the water column with lines starting on the surface going down to about 300 feet. Lots of lights on the bait lines and Hydroglow lights around the boat. Night time they become surface feeders!!!
Daytime is a different animal. It was found that the swords like deep water in the mud during the day between 1200-2200 feet depending on the area. They are fish with heavy weights on an L shaped bar and a heavy duty deep drop type rig with a couple of hooks!!!
Here is a good article about the guy that basically invented the daytime sword fishing!!!
