This research was carried out to estimate variation of stock structure anchovy (Engraulis encrasicolus, L. 1758) (N=7487) of the in Sinop Turkish coast in the southern of the Black Sea between 2000 and 2003. The mean sex ratio was 59 % (female): 41 % (male). The b constant of weight-length relationships were 2.7101, 3.0568, 2.8946 and 2.8695 for 2000-2001, 2001-2002, 2002-2003, and 2000-2003 fishing seasons, respectively. The result showed that fish were 0-3 years old. The von Bertalanffy growth parameter value of L-infinity (cm) were 16.84 cm, 18.46 cm, 18.73 cm and 18.91 cm for fishing seasons, respectively. Total (Z), natural (M), fishing (F) mortality rates and exploitation rate (E) were Z=2.07 year(-1), M=0.30 year(-1), F=1.77 year(-1), E=0.86, respectively for overall samples.
