Sažetak
An assemblage of shallow water fishes was sampled with a small beach seine monthly, during 24 hour periods, between April 2000 and March 2001 at the sandy Duće-Glava beach in the eastern Adriatic. Monthly sets of samples were divided into day and night catches to examine the stability of diel differences in assemblage structure over a one-year period. A total of 284 labrids, mainly juveniles, representing 6 species (Symphodus ocellatus, S. cinereus, S. roissali, S. rostratus, Labrus merula and L. viridis) were sampled during the whole investigation period. each of these labrid species had a different pattern of diurnal and seasonal abundance. S. ocellatus was the dominant species throughout the year. The highest increases in number of all Symphodus species were recorded in the summer period. L. viridis, represented by the largest individuals of all sampled Labrids, were not found during the summer and autumn months. S. ocellatus, S. roissali and S. rostratus appeared to be mainly diurnal, while at night more S. cinereus and L. viridis individuals were caught.
