Abstract

Investigations conducted off the Algerian coast between 1996 and 2001 resulted in the collection of 201 blue sharks, Prionace glauca, including 144 females and 57 males. Prionace glauca is mainly captured off the central area and lesser in the eastern area from the Algerian coast. The central area is probably a mating site of the species. The sex ratio changes are calculated according to specimen sizes and seasons. The recent abundance of the species in Mediterranean areas is discussed.
