Abstract
Prehrambene navike porodice Rajidae na području Jadrana do sada nisu bile istražene. Istraživanje prehrambenih navika morskih predatora ključno je za razumijevanje njihove ekološke uloge u ekosustavu te faktora koji na nju utječu. Na području sjevernog Jadrana, u razdoblju od četiri godine(2011-2015), prikupljeno je 86 primjeraka zvjezdopjege raže (Raja asterias). Raže su izmjerene, određen im je spol te je analiziran sadržaj želudca svakog primjerka. Analizom je utvrđeno da su glavni plijen zvjezdopjege raže dekapodni rakovi, zatim ribe koštunjače. Zastupljenost koštunjača u prehrani raste ontogenteski. Najčešći plijen zvjezdopjege raže bio je rak nosač, Ehtusa mascarone. Mali indeks praznine (VI) ukazuje da je zvjezdopjega raža aktivna vrsta i uspješan predator bentoskih vrsta.
Abstract (english)
Up to this date, no study of the feeding behaviour of the family Rajidae in the Adriatic has been made. The knowledge of the feeding behaviour of marine predators is essential for comprehending their ecological role and factors that affect it. In the Northern Adriatic, in four years time (2011-2015), 86 specimens of starry skate (Raja asterias) have been gathered. All skates were measured and sexed. The stomach content of each skate was analyzed. Analysis showed that their main pray were decapods, followed by teleost fish. The importance of teleosts in the diet of R. asterias shows an oncogenic growth. The most common prey species found was the masked crab, Ethusa mascarone. Small vacuity index (VI) shows that the starry skate is an active and succesful predator of benthic prey species.
