The Growth Properties of Prussian Carp (Carassius gibelio Bloch, 1782) Population in İznik Lake (Bursa/Turkey)

In this study, the growth properties were determined of Prussian carp (Carassius gibelio, (Bloch, 1782)) in Iznik Lake. The study was conducted between from January to December 2006. Age and sex ratio, age-length, age-weight, condition factor, relative length and weight increase were determined from 3114 (1060 male, 2054 female) fishes. The fish belong to population was distributed between 0-VI ages, it and was determined that IIth. ages group is more dominant group respect to others. Mean length and weight were changed from 8.8±0.021 cm to 30,9±0,271 cm and from 14.4±0.079 g to 764,8±13,733 g. Length-weight relation of the population formulation and condition factor were determined as W=0.015756L3.125and 2.350±0.014, respectively.
