Conservation Status of the Tiger Shark
The tiger shark is a relatively fast-growing and fecund species of shark. The tiger shark continues to thrive due to its large, global population and high reproductive rates. Although it is caught regularly in target and non-target fisheries it is currently classified only as a near threatened species on the IUCN Red list.
In spite of these threats, tiger sharks, in general, do not currently face a high risk of extinction. However, if demand continues, especially for their fins, this may result in further declines in the future.
