Sažetak
Diel changes were investigated in fish assemblages associated with shallow seagras (Posidonia oceanica) and bare sand in two southern Adriatic Sea coves. Habitat related differences in assemblages were strong day and night, and were greater than diel changes. The seagrass associated assemblages remained similar day and night and consistently differed from sand associated. In contrast, the assemblages over sand varied on a diel basis as larger individuals of several species (e.g. Atherina boyeri, Sarpa salpa, Conger conger) that resided over other habitats during the day, were caught at night. Both habitats were utilized by newly recruited juveniles of economically important species and their habitat associations generally did not differ on a diel basis. Hence, both habitats are considered important to the fisheries of southern Adriatic.
