With 12 principal rays in caudal fin. 18 vertebrae. Upper jaw non-protrusible. Upper jaw usually with four teeth in outer and three in the inner series on each premaxillary. Capable of rotating eyeballs independently. Triggerfish normally swim by undulating their second dorsal and anal fins, but will use their tail for rapid bursts. Most triggerfishes are solitary diurnal carnivores, feeding on a wide variety of invertebrates including hard-shelled mollusks and echinoderms; some also feed on algae or zooplankton. They lay demersal eggs in a nest which is aggressively guarded by the female, less often by the male. Popular and hardy in aquaria, but often aggressive

Sport Fishing Techniques

	Drifting Drift fishing allows you to fish over a variety of habitats as your boat drifts with the currents or wind movement. You can drift fish on the bottom or change the depth with a bobber or float. Natural baits work best. But jigs, lures and artificial flies will produce good results, too. You can drift fish on the ocean, as well as ponds, lakes, rivers and streams any time of the day and year..

	Still Fishing The simplest of fishing methods can also be the most effective. Still-fishing is a matter of putting your bait in the water and waiting for a fish to find it. Depending on water depth and what you’re trying to catch, you may want to still-fish near the surface, at a mid-water depth, or right down on the bottom. Using a float, or bobber, makes it easy to fish near the surface, or you can add sinkers to your line to fish deeper. Still fishing is a versatile way to go. You can do it from a pier, a bridge, an anchored boat or from shore. You can still fish on the bottom or off the bottom in ponds, lakes, rivers and streams for a variety of species. And you can still fish during most seasons and during any part of the day. You have to be very patient. You need to wait for the fish to bite. Still fishing is a versatile way to go. You can do it from a pier, a bridge, an anchored boat or from shore. You can still fish on the bottom in ponds, lakes, rivers and streams for a variety of species. .
