The pressure on sharks is not limited to fishing, but also includes habitat destruction, pollution, and climate change.

Regional and International Initiatives

Several regional and international initiatives have been established to protect shark populations.

Estimating Mortality Rates for Unstudied Shark Species

The study’s authors compiled data from over 150 published papers and reports, covering nearly 150 different shark species caught by various fishing gears.

The Impact of Shark Retention on Mortality Rates

Shark retention, the practice of keeping sharks on board fishing vessels, has been shown to have a devastating impact on shark populations. The most vulnerable species, including small sharks and several threatened species, are at the highest risk of mortality. • Small sharks, which are often caught accidentally in fishing gear intended for other species, are particularly susceptible to mortality due to their size and the type of fishing gear used. • Several threatened species, including the great white shark, are also at risk due to their limited populations and the fact that they are often caught in deep waters.

Understanding the Importance of Cartilaginous Fishes

Cartilaginous fishes, including sharks, rays, and skates, have been a subject of interest for scientists and researchers for a long time.

Further details on this topic will be provided shortly.
