The Silky Shark (Carcharhinus falciformis) is currently classified as Vulnerable with a decreasing population trend on the IUCN Red List of Threatened Species. Named for its smooth, silky skin texture, this highly migratory, open-ocean predator has suffered an estimated global population decline of 47% to 54% over the last few decades, largely driven by human activities. Major Threats to the Silky Shark
The unique behavior of Silky Sharks—specifically their tendency to migrate over massive distances and aggregate around floating objects—makes them incredibly susceptible to industrial fishing. 1. Overfishing and the Global Fin Trade
Targeted Hunting: Silky Sharks are heavily targeted for their meat, liver oil, and unique skin, which is processed into premium leather.
Fin Market Demand: They are highly prized in the international fin trade, serving as the second most common shark species found in major markets like Hong Kong. 2. Incidental Bycatch in Commercial Fisheries
Tuna Fleet Interaction: Because Silky Sharks naturally swim alongside large schools of tuna and mackerel, they are frequently caught by accident.
FAD Entanglement: Industrial tuna fleets use Fish Aggregating Devices (FADs)—large floating rafts—to attract fish. Silky Sharks gather around these structures and easily become entangled or hooked in longline and purse seine nets. 3. Vulnerable Biology
Slow Reproduction: Silky Sharks have a slow life history. They take 5 to 12 years to reach sexual maturity, undergo a lengthy 12-month gestation period, and produce small litters. They simply cannot reproduce fast enough to recover from intense fishing pressure. 4. Gaps in Marine Protected Areas (MPAs) Silky shark – Save Our Seas Foundation
