This study investigates the biological features of 164 brond-snout Chondrostoma regium (Heckel, 1843) samples caught in Lake Ladik between January and March 2010 such as age and sex composition, length and weight distribution, length, age and weight relations and condition factors. The age was determined from the scales and the age of the fishes were found to change between 2 and 5 years. The range of the total lengths and the weight of the samples were found to be 16.5-25.4 cm and 40.04-192.42 g respectively. The sex ratio (F/M) was found to be 1/0.29. The parameters of von Bertalanffy growth equations were L-infinity = 28.15 cm, W-infinity = 254.16 g, k = 0.30 year(-1) and to = -1.23 year and the growth performance index value (empty set') was found to be 2.38. The length-weight relation was found to be W = 0.0029 TL3.41. There were strong relations among different lengths (p<0.001, r(2) > 0.98). Fulton's condition factor was found to be 1.01 +/- 0.09.
