Abstract: (1242 Views)

In This study, the length-weight and fork-total length relationships, growth pattern and condition factor of Alburnus chalcoides, was estimated during 2006-2007. A total of 170 specimens were collected from the Chelvand, Khalehsara, Siahdarvishan, Sefid, Pol, Tonekabon and Babol rivers. The length-weight relationship was estimated using W = aTL^b, length-length relationship by FL= a+ bTL and condition factor by K = (W/TL^b) ×100 formula. The b-value was 2.5 to 3.25. Also, except Sefid and Babool river populations, others showed positive allometric growth pattern. Condition factor values were calculated 0.72 to 0.96.
