Total lengths and weights of red mullet specimens were ranged from 9.2 cm to 19.2 cm (average: 13.3 ±1.3 cm) and from 8.2 g to 68.6 g (average: 25.7 ±8.0 g), respectively. The samples were grouped densely between 13 and 15 cm. Minimum landing size (MLS) is 13 cm for Mullus barbatus according to Turkish Fisheries Regulation Circular. Thus, 39% of all samples in this study are under legal size. The LWR equation calculated was W = 0.0137 × TL 2.902 ( r 2 = 0.92). Age groups of red mullets in the Black Sea were ranged from I to IV. The mean lengths according to age groups (I, II, III, and IV) were 11.43 ±0.04 cm, 13.22 ±0.04 cm, 15.24 ±0.06 cm, and 18.44 ±0.29 cm, respectively. According to GSI values, reproduction of red mullets is between May and July with the peaks of June–July. T he estimated von Bertalanffy growth parameters with standard errors were L ∞ = 17.64 ±1.43 cm, k = 0.43 ±0.13, and t 0 = –1.33 ±0.37. The m ortality rates (M, F, and Z), and exploitation rate (E) of M. barbatus ponticus were 0.91 year –1 , 0.52 year –1 , 1.43 year –1 , and 0.36, respectively. <hr /> }, number={1}
