Stomachs from 2657 fish, belonging to 32 species, were analyzed. They contained 3403 shrimp, with only 25 pink shrimp. Due to the large size of P. notialis in its marine phases and to the small number of large predators, the predation on this shrimp in the open sea is low. It is the small shrimps, especially Parapenaeopsis atlantica, that are the prey of coastal demersal fish. The current absence of fish predation on P. notialis in the Senegalese sea is generalized to the numerous fishing grounds of this species in West Africa. This is probably not the case for juveniles in estuaries and also in the sea when predatory species were slightly exploited. Related to the shrimp trawl activities, the decrease of the fish predation on pink shrimp in the sea could have permitted an increase of the shrimp catches, human predation replacing fish predation.
