Abstract

In order to determine some parameters of population dynamics of C. DAMASCINA captured from RUDBAL RIVER, Fars Province, 183 specimens were collected. Five AGE classes, ranged from 1+ to 5+ years, and the highest frequency was belong to one years old in both sexes. The overall sex ratio was 1 : 1.28 (males:females). The length and weight range of fish in RUDBAL RIVER were recorded from 55.35 to 245 mm and 2.05 to 158.93 g, respectively. Accordingly, the length- weight relationship was measured as W = 0.00002L2.84 for males, and W = 0.00001L2.94 for females. The Von Bertalanffy GROWTH equation was estimated as; Lt=17.061(1 - e-0.651(t +0.108) ) for males and Lt=34.94 (1 - e-0.19 (t +0.05) ) for females, and consequently, the infinity length in females was remarkably more than males. The condition factor and factor relative status of different AGEs showed that the value of these factors is higher than in males and females respectively, and these increases with AGE in both sexes. Natural mortality rate was calculates as 1.38 and 0.273 in males and females, respectively. Absolute fecundity and relative fecundity in caught females were determined as 4392±1361 and 55.39±30.35, respectively. Relative Length of Gut was revealed that this fish is herbivorous and Fullness index in both sexes at different AGEs showed that its feeding status is fairly poor.
