Growth parameters, length-weight relationship, and condition of the common nase (Chondrostoma nasus)
in the Danube River near Belgrade were analyzed on a sample (n=30) from the commercial catch, caught
between March and May 2017. The total body length of the sampled individuals ranged from 268 to 401
mm, and body weight from 195 to 875 g. Age was determined from scales and individuals aged 5+, 6+
and 7+ were present in the sample, in approximately the same percentage. The regression coefficient of the
length-weight relationship was b = 3.28. The value of b > 3 indicates a positive allometry, which denotes
that the weight growth rate is greater than the length growth rate. The Fulton’s condition factor ranged
from 0.90 and 1.36, with the mean value of 1.07. The parameters of the von Bertalanffy growth function
were L∞ = 697.84, k = 0.08, and t0 = -1.72. The estimated phi-prime growth performance index (j') was
4.60. The lengths were back-calculated using the method of ...Monastyrsky, and the greatest relative growth
increment was observed in the first and second year of life.
