Abstract
Riba salpa (Sarpa salpa) jedna je od značajnijih vrsta porodice ljuskavki (Sparidae) u Sredozemlju, no podaci o njenoj ishrani u sjevernom Jadranu nisu dovoljno istraženi. U razdoblju od studenog 2023. do travnja 2024. godine, u Medulinskom zaljevu prikupljene su 54 jedinke salpe u sklopu gospodarskog ribolova. Analizirani su njihovi morfometrijski parametri, spol, starost, te indeksi kondicije: Fultonov indeks (CF%), hepatosomatski indeks (HSI%) i gonadosomatski indeks (GSI%). Starost jedinki... More određena je pomoću sagitalnih otolita i ktenoidnih ljuski, a hrana je zabilježena kod svih jedinki. Od 51 analizirane jedinke, 38 su ženke (75%), a 13 mužjaci (25%), s prosječnom starošću od 3,24 godine. Najveći CF% za ženke iznosio je 1,38 u studenom, a za mužjake 1,46. Najviši HSI% zabilježen je u siječnju, dok su ženke imale najveći GSI% u siječnju (0,30), a mužjaci u veljači (0,33). U prehrani je identificirano pet funkcionalno-morfoloških skupina makroalgi: vapnenaste razgranate, razgranate, nitaste, kožaste i listolike, dok skupina inkrustriranih makroalgi nije zabilježena. Dominantne vrste algi bile su Halimeda tuna, Caulerpa cylindracea i Laurencia obtusa, a morske cvjetnice zabilježene su kod 91% jedinki. Puževi, kao plijen životinjskog porijekla, rijetko su prisutni. Rezultati pokazuju da vrsta S. salpa u Medulinskom zaljevu preferira makroalge i morske cvjetnice, uz minimalan unos životinjskog plijena, što doprinosi boljem razumijevanju njene prehrane i ekološkog utjecaja u ovom ribolovnom području.

Abstract (english)
Salema porgy (Sarpa salpa) is one of the most important species of the family Sparidae in the Meditteranean Sea, but still, data on its diet in the northern Adriatic have not been sufficiently researched. From November 2023 to April 2024, 54 individuals of salema were collected in the Bay of Medulin as part of the commercial fishing. Their morphometric parameters, gender, age, and fitness indices were analyzed: Fulton index (CF%), hepatosomatic index (HSI%) and gonadosomatic index (GSI%). The... More age of the individuals was determined using sagittal otoliths and ctenoid scales, and food was recorded for all individuals. Of the 51 analyzed individuals, 38 were females (75%), and 13 were males (25%), with an average age of 3,24. The highest CF% for males and females was 1,38 in November. The highest HSI% of females was recorded in January (0,30) while for males in February (0,33). Five functional-morphological types of macroalgae were identified in the diet: articulated, corticated, filamentous, leathery and foliose, while crustose macroalgae were not recorded. The dominant species of algae were: Halimeda tuna, Caulerpa cylindracea and Laurencia obtusa. Seagrass was recorded in 91% of individuals. Gastrophods, as prey of animal origin, were rarely present. The results show that S. salpa in Medulin Bay prefers macroalgae and seagrass, with a minimal intake of animal prey, which contributes to a better understanding of its diet and ecological impact in this fishing area.
