| Abstract: | Three hundred eighty eight were aged by scales for age determination. Tor brevifilis brevifilis produces new annual rings in a single year, with a peak in April. Analyzing the body length, the body weight, and the age of the catched shows that 388 speciment mainly consist of single aged fishes which take Tor brevifilis 63 92% of the whole population, The body length and the scale length were linear correlated; the body length and the weight to be exponential correlated. The growth parametres L, W, K and T have been estimated to be 70 43,5?961 50,0 223?1 and 0 022?4 respectively. The age of 4 95 years Was the turning point of growth with body weight 1?768^23 gram. The fast growing period was in the age of one and two. At this time, thefish produces new annual rings. |
