Abstract


The  length- weight  relationship  and  condition  factor  was  investigated from 500 Specimen of Orechromis niloticus maintained in concrete pond at Habib ADM Hub, Balochistan, Pakistan, for six months March to September 2008. The experimental fish was ranged from 15. 5-37. 8 cm and 50. 4 - 635. 4g in length and weight respectively. The value of regression co-efficient obtained for the length-weight relationship b=4. 55. This suggests positive allometry growth from entire specimen sampled. There was no significant statical difference in the regression co-efficients. The mean values of condition factor computed for all the specimen of Oreochromis niloticus  was 1.07 ± 0.45, which  indicated that the specimens were healthy. The length-weight relationship of sexes combined as shown by the following equation:
Log W= 4.07 + 4.55 Log L.
