The Sandbar Shark, scientifically known as Carcharhinus plumbeus, is a member of the Carcharhinidae family. This marine species is well known for its high fineness and elongated, rounded snout.
Conservation Status
The Sandbar Shark is currently listed as “Vulnerable” on the IUCN Red List. Conservation efforts for the species include management measures such as fishing restrictions, bycatch reduction methods and protective zones.
Statistics
| Statistic | Average | Range |
|---|---|---|
| Length | 1.5-2.5 m | 1.2 – 3 m |
| Weight | 45-100 kg | 30 – 110 kg |
| Average Lifespan | 35-40 years | 30 – 45 years |
Other notable stats: Sandbar sharks reproduce only once every two years, with a gestation period of around one year.
Distribution
The Sandbar Shark is found in the Indo-Pacific region particularly around Taiwan, and the western Atlantic Ocean from Massachusetts to Brazil. There is no known migration pattern for this species as they are largely sedentary.
Habitats
The Sandbar Shark is predominantly a costal-pelagic species, found in subtropical waters. They occupy depth ranges of 20 – 280 meters and prefer temperature ranges of 12 – 24°C.
When and Where to See
While Sandbar Sharks can be spotted year-round, their activity increases during warmer months. These species are generally more active during night time.
Best Fishing Locations
- Gulf of Mexico, USA
- Bay of Plenty, New Zealand
- Western Atlantic, Massachusetts to Brazil
- Indo-Pacific region, around Taiwan
General Tips: Sandbar sharks prefer warmer, coastal waters. Look for areas where there are shoals of small fishes as these are their primary food source.
How to Catch
Preferred bait or lures include squids and small fishes like mackerel or herring. Fishing techniques such as bottom fishing are commonly used. The best time to catch Sandbar Sharks are during warm months, particularly during night time.
Identification Guide
Sandbar sharks are recognized by their high fins, elongated, rounded snout and dusky-colored body. They exhibit a bronze-grey color on top and a white underside. Their first dorsal fin is large and very pointed.
Culinary Information
Sandbar Shark meat is considered a delicacy in some cultures. The meat is often grilled, baked, or used in stews. It has a mild flavor with a slightly sweet aftertaste.
Additional Information
Behavior: Sandbar sharks are nocturnal hunters, feeding primarily on small fishes, squids, and crustaceans. They host a viviparous reproduction mode, which means the mother gives birth to live young.
Predators: Young Sandbar Sharks fall prey to larger sharks while human fishing activities pose the greatest threat to adults.
Cultural/ Historical Significance: In Hawaiian culture, sharks are considered to be gods of the sea, providing protection for humans. In modern times, Sandbar Sharks have been the subject of many documentaries due to their vulnerable conservation status.
