ABSTRACT

 This study was carried out to describe the length-weight relationship (LWR), length-length relationships (LLRs) and
condition factor (K) in 926 specimens belonging to 20 freshwater fish species of family cyprinidae. Fish samples were
collected on a monthly basis from August 2013 to July 2014 at Taunsa barrage from the Indus River, Punjab,
Pakistan. The values of parameter b for LWRs ranged from 2.16 – 4.10 suggesting the isometric and allometric
growth pattern in fishes of family cyprinidae. The results of K factors ranged from 0.645 – 1.836 also determine both
negative growth tendency in some fish species and positive growth tendency in other fish species. This study aimed
to incorporate some more information in the aquaculture sector of the country to depict the population conditions of
fish species in the Indus River.
