Abstract:

The present study aims to study the length-weight relationship and condition factor of Capoeta trutta in Gamasiab River from Iran. A total of 40 individuals of C. trutta were sampled from Gamasiab River by Electro fishing on September 2014. Total Length (cm) and body weight (g) for each specimen was taken by a digital slide caliper and balance, respectively. In the present study, Total length and weight ranged from 10.5 to 19.8 mm and 11.86 to 76.82 g, respectively. Average total length and weight was 14.41±0.91 (SD) mm and 34.7±0.86 (SD) g, respectively. The b value was 3.054 that is significantly larger than 3, indicating a positive allometric growth for the considered group. In this study, condition factor (K) of fish was 0.93. This study provides basic information on C. trutta for fishery biologists in Iran.


Keywords: Length, Weight, Relationship, Condition factor, C. trutta.
