Sažetak
The stomach contents of 964 damselfish collected in the eastern centralAdriatic in 1992 and 1993 were examined to assess the diet, as influenced by season and fish size. Damselfish is carnivorous from the juvenile stage onward, feeding on a narrow range of plankton and benthic prey items. Higher intesity of feeding activity in spring could be related to temperature and/or gonadal maturation. During all seasons copepods constituted the most important food resorce by weight, number and frequency of occurence.Appendicularia and cladocerans were the second most important food category. Dietaryy overlap was relatively high, indicating that the feeding spectrum of damselfish changed little across seasons, but for size groups was small, indicating greater changes in feeding spectrum.
