Abstract

Human activities have been widely accepted as a driver of rapid trait change in wild fish stock globally with help of stressors. Fishing and invasive species are among the most important stressors which are affecting freshwaters fish stock from the lotic and lentic ecosystem. Study was carried out between the periods November 2015 to October 2016 from the Ghaghara river at Faizabad, India. The age composition of C. mrigala varied from 0+ to 8+ from the Ghaghara river at Faizabad. On the basis of sampled specimen in the length range from 15.7 to 88.7cm showed that the fish attained the mean length 25.3cm in 1+, 43.8cm in 2+, 57.5cm in 3+, 67.2cm in 4+, 74.7cm in 5+, 79.6cm in 6+, 83.9cm in 7+ and 87.3cm in 8+ age classes. The growth increments of C. mrigala was recorded as 25.3cm, 18.5cm, 13.7cm, 9.7cm, 7.5cm, 4.9cm, 4.3cm and 3.4cm for 1+ to 8+ age classes, respectively. The maximum growth increment was estimated in 1st year and moderate in the subsequent years.
