The deepwater pink shrimp Parapenaeus longirostris (Lucas 1846), is one of the species of Decapod Crustacea targeted by coastal and offshore demersal fisheries in the western Mediterranean in general, and on the Algerian west coast in particular. This book provides an initial overview of the diet of the pink shrimp Parapenaeus longirostris in western Algeria. It accounts for a significant proportion of landings at many Algerian fishing ports. The aim is to fill in the gaps in the ecobiology of this species in general, and its diet in particular.
