Habitat
Southern tilefish inhabit the continental shelf in deep waters, typically between 100 and 400 meters, over sandy or muddy bottoms with rock structures. They are found along the western Atlantic Ocean, from Brazil to Argentina, preferring areas with soft substrates for burrowing.
Diet
Southern tilefish primarily feed on benthic invertebrates such as crabs, shrimp, and mollusks, along with small fish and worms. They forage on the seafloor during the day, using their sensitive mouths to detect and capture prey hidden in the sediment.
Behavior
Southern tilefish are generally solitary or form small groups, often burrowing into the seafloor to create dens for protection and resting. They are diurnal, most active during the day for feeding, and exhibit territorial behavior around their burrows. These fish are not highly migratory, staying within preferred depth ranges.
Fishing
Southern tilefish are a rewarding deep-water target for anglers in the Southwest Atlantic, from Brazil to Argentina, where recreational fishing supports conservation through license fees and habitat protection programs that sustain these offshore ecosystems. Use bottom fishing techniques with heavy gear to reach depths of 100-400 meters over sandy or muddy bottoms with rock structures, dropping baited hooks and waiting for bites as the fish forage during the day; jigging with weighted lures can also entice strikes by mimicking their prey. Recommended tackle includes a stout rod rated for 50-80 lb test line, a high-capacity reel for deep drops, and strong leaders to handle their burrowing behavior, paired with bait like live shrimp, crabs, or squid to match their diet of benthic invertebrates. The best season is summer during their spawning period, with optimal fishing times in the daytime when they are most active on the seafloor. Focus on continental shelf edges with soft substrates for the highest success rates, ensuring you follow local regulations that promote sustainable populations, such as size and bag limits, which are effective tools for maintaining healthy stocks. The IGFA all-tackle world record for tilefish species is 42 pounds, but notable Southern tilefish catches reach up to 18 pounds 11 ounces, highlighting the thrill of this sport while anglers contribute to conservation through catch-and-release practices in areas with potential overfishing pressures.
