Silky Shark

About the Silky Shark

The Silky Shark is a sleek, streamlined pelagic predator, distinguished by its relatively small second dorsal fin and the smooth, 'silky' texture of its skin. Its body is typically dark grey or bronze dorsally, fading to white on its belly, with no prominent markings. Its pectoral fins are long and pointed, and its fins often have dusky tips, which can help in identification. The first dorsal fin originates behind the free rear tips of the pectoral fins, a key identification feature. This active shark can grow quite large, making it a formidable opponent on the line.

Habitat

As one of the most abundant sharks in the pelagic zone, the Silky Shark roams the open ocean, rarely venturing into shallow coastal waters. It prefers tropical and subtropical waters globally, often found near the edges of continental shelves and around oceanic islands. These sharks are highly mobile, often associated with schools of tuna and other pelagic fish.

Distribution

This species has a widespread global distribution, inhabiting tropical and subtropical waters across the Atlantic, Pacific, and Indian Oceans. They are known for their highly mobile and migratory nature, following warm currents and prey concentrations.

Behaviour

Silky Sharks are opportunistic and voracious predators, primarily feeding on pelagic bony fishes like tuna, mackerel, and sardines, but also squid and crustaceans. They are highly active swimmers, often observed cruising in the upper water column. Their migratory patterns often coincide with the movements of their prey, making them a seasonal target in many areas. They are known to form large aggregations, especially around productive fishing grounds.

Edibility

★★★★★

While the meat is considered edible, often marketed as 'flounder' or 'rock salmon', Silky Shark is not widely sought after for its table quality due to concerns regarding sustainability and potential mercury accumulation. The flesh is typically firm and white.

Lure suggestion

Targeting Silky Sharks requires heavy-duty offshore tackle, including 80-130 lb class rods paired with large capacity reels. Natural baits such as whole or cut tuna, bonito, mackerel, or squid are highly effective, presented on large circle hooks (16/0-20/0) with heavy wire leaders (300-500 lb). Chumming with oily fish offshore is crucial for attracting these pelagic sharks to the boat. Present baits either free-lined or suspended beneath a balloon.
