"Blue Shark," Wikipedia, the free encyclopedia.It is estimated that 10 to 20 million of these sharks are killed each year as a result of fishing. The flesh is edible, but not widely sought after; it is consumed fresh, dried, smoked and salted and diverted for fishmeal. There is a report of high concentration of heavy metals (Hg, Pb) in the edible flesh. The skin is used for leather, the fins for shark-fin soup and the liver for oil. Blue sharks are occasionally sought as game fish for their beauty and speed. Blue sharks rarely attack humans. From 1580 up until 2013 the blue shark has been implicated in only 13 attacks upon humans, four of which ended fatally.
