This abundant pelagic and oceanic shark is widespread in temperate and tropical waters. It is relatively fast-growing and fecund, maturing in 4–6 years and producing average litters of 35 pups. The Blue Shark (Prionace glauca) is taken in large numbers (an estimated 20 million individuals annually), mainly as bycatch, but there are no population estimates and many catches are unreported. The few fishery assessments carried out suggest relatively little population decline. There is concern over the removal of such large numbers of this likely keystone predator from the oceanic ecosystem.
