This study was carried out to evaluate growth pattern of Cauacasian goby (K. caucasica) with 464 fish samples that obtained from February to May 2012 with beach line net. Sex ratio of male to female was 1:1.06 which does not show a significant difference between male and female in the population (X² = 0.422, p > 0.05).  Maximum total length and weight were recorded as 41.78 mm and 1.08 g for females, and 46.12 mm and 1.26 g for males. The weight - length relation for female was W= 0.0083 TL3.20 (r2 = 0.95) and the weight - length relation for male was W= 0.0079 TL^3.20 (r² = 0.97) and the total relation was W= 0.0082 TL^3.19 (r²= 0.96). The results showed positive allometric growth (t-test, t_male= 4.94, t_female = 4.22, t_population= 5.90, p< 0.05). Reviewing the condition index revealed that for both sexes, the highest amount of this index were in July and August and the lowest for males was in April and for females were in April and February.
