Abstract

Tijekom jedne godine ispitivane su prehrambene navike glavoča travaša, Zosterisessor ophiocephalus (Pallas, 1814), ovisno o godišnjem dobu, spolu i veličini. Pregledan je želučani sadržaj 302 uzorka, od čega je 91 želudac bio prazan. Uzorkovana populacija sastojala se od 136 ženki (45,03 %) u rasponu od 6,8 do 19,3 cm (13,30 ± 2,24), 156 mužjaka (51,65 %) u rasponu od 6,1 do 20,2 cm (14,14 ± 2,91) i 10 jedinki neodred strok signenog spola (3,31 %) dužine od 5,6 do 16,0 cm (10,07 ± 2,91). Glavoč travaš je uglavnom mesožder. Prehrambene sklonosti med strok signu spolovima i veličinama nisu se statistički razlikovale. Rezultati pokazuju da je glavoč travaš oportunistička vrsta koja se hrani širokim spektrom plijena. Deseteronošci su bili najvažniji plijen (IRI =3208,49), a slijede Osteichthyes (IRI=490,03).

Feeding habits of Grass goby, Zosterisessor ophiocephalus (Pallas, 1814) related to season, sex and size were examined during one year. Stomach contents of 302 specimens were examined, of which 91 stomachs were empty. The sampled population consisted of 136 females (45.03%) ranging from 6.8 to 19.3 cm (13.30 ± 2.24), 156 males (51.65%) ranging from 6.1 to 20.2 cm (14.14 ± 2.91) and 10 unspecified (3.31%) individuals of a length of 5.6 to 16.0 cm (10.07 ± 2.91). Grass goby is mainly carnivorous. The dietary preferences among sexes and sizes did not differ statistically. Results indicate that Grass goby is an opportunistic species that feeds on wide spectrum on prey. Decapods were the most important prey (IRI =3208.49), followed by Osteichthyes (IRI=490.03).
