The growth patterns of specie Caspian Roach (Rutilus lacustris) were studied to determine dynamics of the pattern during early life stages. For this purpose, a total of 5043 Roach larvae were collected during a period of 10 year period (2008-2017). The total length and total weight for the Roach larvae were 0.90-5/70 mm and 0.01-1.80 g.The highest Condition factor for larvae of Roach was 1.16 ± 0.63 in 2011. The highest instantaneous growth factor was observed in the first 10 to 20 days. The relationship between length and weight showed that the growth pattern of the larvae of the Roach was in the range of 3.87 to 2.87. Considering b-values indicates that growth pattern has temporal variation for the studied specie.
