Use structure at all depths to cover all seasons of the year and all fishing and growth scenarios. Only part of the year is a thermocline present. Most predator fish love to be able to move up and down in the water column (subject to O2 requirements)for various reasons (protection , feeding and comfort/stress reduction). There are interesting studies on predators' use of the thermocline for feeding (trapping prey against the thermocline)and escape (they can and do go into the thermocline for feeding and escape).
