Length-weight relationship of Tilapia niloticus in concrete pond of Habib ADM, Hub, Balochistan

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.
