Abstract:

Length-weight (LWR), length-length (LLR) relationships and condition factor (K) were calculated for three fish species of Taleghan River (Alborz Province, Iran). In total 113 fish specimens were collected by electrofishing, anesthetized in 1% clove solution in the field and immediately their weights and lengths measured, finally all samples returned to river. The values of the parameter slope (‘b’) in the length–weight relationship were 2.966 for Barbus ciry, 2.96 for Capoeta gracilis and 3.053 for Oxynoemacheilus bergianus. The all relationships between TL, FL and SL were linear (for all cases: r2> 0.98). Also, the coefficient ‘K’ in the condition factor equation were calculated 0.898 for B. ciry, 0.833 for C. gracilis and 0.830 for O. bergianus.
