Abstract :
The length-weight relationships for three fish species from Beheshtabad River, Karun River Drainage (Western Chaharmahal and Bakhtiari Provinces, Iran) were investigated. The values of the slope parameter (b) in the length-weight relationship equations were determined as 2.79 for Capoeta damascina, 3.10 for Chondrostoma regium and 3.09 for Oncorhynchus mykiss, all of which were significantly different from the expected b=3 value, indicating a negative allometric growth pattern for Capoeta damascina and positive allometric growth patterns for Chondrostoma regium and Oncorhynchus mykiss.
