The stomach contents of red gurnard, Aspitrigla cuculus (Osteichthyes: Scorpaeniformes), specimens collected in the Northern-Central Adriatic Sea have been analyzed to determine diet according to fish size and depth. Crustaceans, particularly Lophogaster typicus (Lophogastrida) and Decapoda represented the basic food for all sizes (%IRI=99.12 for juveniles; %IRI=97.92 for adults). The diet of adults was similar to those of juveniles and it does not change with depth, indicating trophic specialization and preference for prey with a wide distribution.

Abstract
The stomach contents of red gurnard, Aspitrigla cuculus (Osteichthyes: Scorpaeniformes), specimens collected in the Northern-Central Adriatic Sea have been analyzed to determine diet according to fish size and depth. Crustaceans, particularly Lophogaster typicus (Lophogastrida) and Decapoda represented the basic food for all sizes (%IRI=99.12 for juveniles; %IRI=97.92 for adults). The diet of adults was similar to those of juveniles and it does not change with depth, indicating trophic specialization and preference for prey with a wide distribution.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
