摘要
The present study was carried out to assess the population. structure, growth and condition factor of carp (Cyprinus carpio L., 1758), between June 2012 and June 2013 in Mogan Lake. The age of Cyprinus carpio caught from Mogan Lake ranged between I to VI years. The sex percentage was determined as 49.45 % males and 46.15% females. Fork length of fish ranged from 14.0 cm to 41.5 cm and body weight of fish ranged from 65 g to1750 g. The von Bertalanffy growth equations were: L-t =49.603 [1 - e(-0.241 (t+1.74))] for females and L-t = 49.060 [1 - e(-0.259 (t+1.44))] for males; W-t = 2623.07 [1 - e(-0.241 (t+1.74))] (2.874) for females; W-t = 2669.75 [1 - e(-0.2.59 (t+1.44))] (2.7529) for males. The condition factor was calculated as 1.98 and 1.99 for females and males, respectively.
