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.
