Rast i prehrambene navike vučića, Serranus hepatus (Linnaeus, 1758) u zaljevu Izmir, Egejsko more

Age, growth and diet of brown comber, Serranus hepatus, were determined from specimens collected in Izmir Bay, Aegean Sea. Total length ranged from 5.20 to 11.70 cm, while weight varied between 1.89 and 24.97 g. The length-weight relationship was W=0.0157*L2.998. Age was determined by otolith readings, where a maximum age of 4 years was observed. The von Bertalanffy growth parameters were estimated as L∞=11.90 cm, k=0.56, to=–1.14. Stomach content analysis revealed that the species is carnivorous, with benthic crustaceans constituting the main food in the overall diet composition.Starost, rast i prehrambene navike vučića, Serranus hepatus, su ustanovljene na primjercima prikupljenim u Izmirskom zaljevu, Egejsko more. Ukupna duljina kretala se od 5.20 do 11.70 cm, a težina od 1.89 do 24.97 g. Duljinsko-maseni odnos je iznosio W=0.0157*L2.998. Starost je određena prema očitanju otolita, te je ustanovljena maksimalna starost od 4 godine. Von Bertalanffy-ijevi parametri rasta su iznosili kao što slijedi: L∞=11.90 cm, k=0.56, to= –1.14. Analiza sadržaja želudaca je otkrila da ova vrsta spada u mesoždere jer su u njezinoj prehrani najzastupljeniji bili raci
