Diet overlap of juvenile salema (Sarpa salpa), bogue (Boops boops) and common two-banded sea bream (Diplodus vulgaris) in the south-eastern Adriatic

Summary The food compositions of salema Sarpa salpa, bogue Boops boops and common two‐banded seabream Diplodus vulgaris in Donji Molunat Bay (south‐eastern Adriatic) were studied in order to evaluate the diet overlap among them. Fish were collected from March to July 2009 using a beach seine net. Three species of crustaceans were the most common prey, the most abundant being copepods. A significant overlap in the diet calculated using Schoener's index was recorded in May when the index was 0.9266 for bogue and salema, 0.6091 for bogue and common two‐banded seabream, and 0.6142 for common two‐banded seabream and salema.
