The length-weight relationships for three fish species from Beheshtabad River, Karun River Drainage (Western Chaharmahal and Bakhtiari Provinces, Iran) was investigated. The values of the slope parameter (b) in the length–weight relationship equations were determined as 2.79 for Capoeta damascina Valenciennes, 1842, 3.10 for Chondrostoma regium and 3.09 for Onchorhyncus 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 Onchorhyncus mykiss.
