People who want to fish for black snapper should also pay attention to these matters:
Don't choose the bottom water layer as the lower bait point. Snapper are bottom fish, so many anglers choose to bait in the bottom water when choosing a baiting spot, believing that snapper stay more in deeper water, or wrongly assuming that snapper in deeper water will be larger in size. Snappers are usually found in mid-water and are better suited to feed in water with reefs.
Black snappers generally feed on shellfish and invertebrates on the sea floor, most of which live between crevices in the reef, a warm, bright layer of water that is better suited to their survival and reproduction. As a result, snappers swim upstream from the depths through holes or gaps between the reefs to get to the more food-rich layer.
Lay your bait without any cover, as this layer is shallow and snappers are sensitive to shadows and other things that may be out of place.
Be quick when setting the hook, if a snapper is hooked but takes too long to set the hook, his kind will be able to recognize it and leave the area.
