The blue shark, or Prionace glauca is a unique marine species known for its characteristic dark-blue hue and torpedo shape. Globally, it is one of the most common sharks and can be found in temperate to tropical waters across almost every major ocean line.
A Swift and Efficient Hunter
Blue sharks are among the most adept of all shark species at hunting, as they have a deadly trifecta: speed, maneuverability and senses skilled enough to allow them to hunt with pinpoint accuracy. With their aerodynamic bodies, they can fly up to 30 miles per hour. Armed with sharp, exploitable teeth and a mighty chomp they can grip up on all kinds of delicious insecure prey like bony fish, squid and other sharks.
A Global Traveler
Blue sharks are very migratory and may travel from one side of an ocean to another. Oceanic wanderers often far from land the birds can dive to great depths – over 1,000 meters (over a mile) deep. It provides an access to a broad spectrum of food and habitats as they traverse large distances.
Conservation Challenges
While still found in some of their original ranges blue sharks are considered one of the greatest nightmare by over fishing, as well as excessive capture and habitat damage. They are also frequently caught as bycatch in longline and gillnet fisheries, resulting in high mortality. Furthermore, pollution and climate change bring even more dangers to his species.
Conservation Efforts
A wide range of conservation measures is in place globally to protect blue sharks and related species. These efforts include:
Encourage sustainable fishing methods — including selective gear and catch limits to help protect fish populations.
Reducing Human Impact: Designation of marine protected areas to protect critical habitants and decrease impacts from humans on our oceans.
Cooperate internationally: Promote international cooperation to tackle transboundary issues like illegal, unregulated and undeclared fishing
Public Education: Teaching the public about marine conservation and the dangers to all living creatures of ocean habitats.
So when we know how blue sharks are eco system, what sorts of trouble come upon them to the extent that populations have decreased, and assess together on conservation measure this is basing our foundation for their survival in a long term. By promoting ocean-friendly fishing, safeguarding marine environments and educating the public about seabird threats we can help create a cleaner, more sustainable ocean.
