Blue sharks are highly migratory species, travelling vast distances across temperate and tropical waters. Their migrations are influenced by seasonal changes, prey availability, and the need for optimal environmental conditions. [ 22 ]
The blue shark is an open-ocean (or pelagic) species that visits UK seas in summer months. In the Atlantic, they appear to follow a clockwise route, following the Gulf Stream to the UK from the Caribbean and returning there following the Atlantic North Equatorial Current. Blue sharks are active predators and feed mainly on small fish and squid ...
Aug 13, 2014 · Spatial structuring and segregation by sex and size is considered to be an intrinsic attribute of shark populations. These spatial patterns remain poorly understood, particularly for oceanic species such as blue shark (Prionace glauca), despite its importance for the management and conservation of this highly migratory species. This study presents the results of a long-term electronic tagging ...

The blue shark is a highly migratory species that regularly undertakes transatlantic migrations of thousands of miles. Diet includes fishes, squid, smaller sharks, and pelagic crustaceans. Known to scavenge on dead marine mammals and discarded fishing catches.
The blue shark is probably the widest ranging shark found in the main oceans and seas of the world, from the surface to at least 400 m depth. Blue sharks are a migratory species. Depth range
Feb 1, 2024 · The blue shark (Prionace glauca), a highly migratory and wide-ranging shark, has been classified as Critically Endangered in the Mediterranean Sea by the International Union for Conservation of Nature since 2016 due to overfishing. Surprisingly, basic information on its biology and ecology, essential for its conservation, remains unknown, and its regional stock has not been assessed.

Mar 28, 2024 · Over the last three decades, the advent and the continuous sophistication of telemetry devices have revolutionized our understanding of how pelagic sharks move and exploit their three-dimensional underwater habitat, with implications for management and conservation. In this study, conventional (4,648) and electronic (18) tags were used to assess the horizontal and vertical movements of blue ...
