摘要：

Population During 2004-2005 Fishing Season. The main aim of this study was to estimate some of the basic characteristic of anchovy population in the Eastern Black Sea. Total of 1499 individual were examined. The samples were between 0 and III ages groups and their ratios 8 %, 54 %, 23 %, 15 % respectively. The sex ratios found as 52 % females and 44.5 males and 3.5 % determined as unmatured. The mean length 11.359 +/- 0.031 cm, the mean weight 9.275 +/- 0.066 g and the length-weight relationship and the growth parameters calculated as W=0.0091L(2.7948), r=0.95, L-infinity=16,114, W-infinity=23.889, k=0.2919 and t(0)=-2.5626 respectively. The data obtained in the 2004 fishing term; living rate (S), total mortality rate (Z), natural mortality rate (M) and fishing mortality (F) ratio determined as S=0.39, Z=0.93, M=0.39 and F=0.54 respectively.
