Comparative study of growth patterns Alburnoides namaki Bogutskaya and Coad, 2009 in the Salt Lake Basin

To study the growth patterns of Alburnoides namaki in the salt lake, For this purpose a total of 325 specimens were sampled using by By hand trawl net with two centimeters mesh (20 mm distance from node to node) in winter of 2018. Male to female sex ratio in the population studied showed There was no significant difference between males and females in studied areas (X2 Gloushjerd=0.074, X2 Yunji=0.453, X2 Tureh=1.080,). Length-weight relationship in the population Golushjerd river W=0.0097TL3.15, In the population of the Yunji river W=0.0138TL2.98 and In the population of the Turh river W=0.0062TL3.25 Was obtained. The results showed that the growth pattern of this species in the populations of Goloshjerd and Tureh river is positive allometric and In the population of the Yunji river, it was isometric (t-test, tGloushjerd = 1.73, tYoonji = 0.26, tToure = 2.67,  p < 0.05). The condition factor between ages showed that for both males and females, its highest value was observed for all ages in the Yunji river. The highest value of this coefficient was observed for male in the Gloushjerd river and Yunji river at the age of +4 and in the Toure river at +1 and +5. Maximum Growth rate In Gluoshjerd and Yunji rivers for both males and females At the age of 2+-3+ years and  In the Toure River at 1+-2+ was obtained. The von Bertolaniffy Growth model (VBGF) for the Gluoshjerd river Population Lt=172.10(1-e-0.10(t+1.70), For the Yunjji river population Lt=171.95(1-e-0.09(t+2.39) and for the Tureh river population Lt=193.30(1-e-0.07(t+2.47) was calculated.
