Observations on the biology and ecology of the blue shark in the North‐east Atlantic

Of 159 blue sharks Prionace glauca examined (59% female, 41% male) from oceanic waters SW of Britain and Ireland, all but two males were immature. Size‐at‐age and growth rate were similar to previous studies in the North Atlantic, while stomach contents included cephalopods, fish, cetaceans, and to a lesser degree, birds and crustaceans.
