Age and growth determination of the grass goby, Zosterisessor ophiocephalus (Pallas, 1814) in Novigrad Sea (Adriatic Sea)

The main objective of this study was to investigate the relationship between age and growth in the grass goby, Zosterisessor ophiocephalus (Pallas, 1814) in the Novigrad Sea. A total of 342 specimens, ranging from 4.5 to 20.2 cm were sampled. The age was determined by using otolith readings. Five age classes were established. Predominance of age class 2+ and 3+ in the total catch was noted. In comparison of sexes, differences were seen in the age classes. Males ranging in length from 6.7-20.2 cm were the most numerous in the 3+ age class, while females ranging in length 7.8-18.3 cm were the most numerous in the 2+ age class.
