Sažetak
The total length of 1065 individuals of Zosterisessor ophiocephalus ranged from 5.4 to 20.0 cm (mean 12.64 ± 2.51) and weight from 1.20 to 76.96 g (21.34 ± 12.70). The calculated length-weight equation for all individuals was TW (g) = 0.010TL2.90, R2 = 0.950 ; for females TW (g) = 0.012TL 2.890, R2 =0.951 and for males TW (g) = 0.012TL2.895, R2 = 0.950. There was no statistically significant difference of the length-weight regressions between sexes (ANOVA, p > 0.05). The ages ranged from 1 to 5 years. The values of the VBGE parameters pooled for both sexes are L∞ = 21.14 cm, K = 0.35 year-1, t0 = - 0.32 year-1. Total mortality, corresponding to descending limb of the length- converted catch curve, was Z = 0.442 per year for females and Z = 0.510 per year for males.
