Study on the growth parameters of Capoeta trutta (Heckel, 1843) in Shour River, Iran
چکیده:   (4298 مشاهده)
In this study growth characteristics of 815 tuwini (Capoeta trutta) in Shour River were investigated during July 2010 through June 2011. The population was composed of 62.94% females and 32.02% males. Sex ratio was 1: 1.96, with significant differences observed at 1:1 (x2= 150.6 df= 1 p<0.05). The age distribution of this population ranged from <1 to 6 years. The distribution of length and weight was between 95 and 300 mm. The average length, except in <1 year olds, was statistically significant between sexes and average weight in all age groups was statistically significant between sexes (p<0.05). Weight-length relationship was determined as W=0.0115L2.9475 (R=0.91) in males and W=0.0096L3.0025 (R= 0.88) in females. Von-Bertalanffy growth equation was Lt= 24.5(1-e -0.333(t+2.54)) for males and Lt= 36.4 (1- e -0.129(t+4.02)) for females. Growth performance index was also estimated as Φ=2.301 in males and Φ=2.223 in females.
