length-weight relationships for three species from beheshtabad river, karun river drainage, iran

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 ..
