• Resumen

  • The trophic relations of five coastal Perciformes at northern Chile were analyzed on the basis of 151 specimens of Acanthistius pictus, Paralabrax humeralis, Pinguipes chilensis, Anisotremus scapularis and Cheilodactylus variegatus collected off Iquique, in April 1996, as a preliminary way to identify trophic guilds of subtidal fishes; A. pictus, P. humeralis and C. variegatus, had the crustaceans Rhynchocynetes typus, Pseudosquillopsis lessoni and Allopetrolisthes angulosus, respectively, as the best represented items. In A. scapularis and P. chilensis the best represented items were the mollusks; however for the last species, the main food was the crustacean Cancer setosus. These fish are essentially benthophagous carnivores with a variable trophic spectrum(8 to 36 items).
