Investigating the growth patterns of Knipowitschia caucasica (Berg, 1916) in Gomishan wetlands- South East Caspian Sea

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 TL3.20 (r2 = 0.97) and the total relation was W= 0.0082 TL3.19 (r2= 0.96). The results showed positive allometric growth (t-test, tmale= 4.94, tfemale = 4.22, tpopulation= 5.90, p
