Abstract

The present study was carried out to investigate some aspects of the biology of Oreochromis niloticus, it has ecological and economic importance, found in Khashm El-Girba market; here, we describe the length-weight relationships, condition factors and sex ratio of O. niloticus.  A total of 525 specimens were collected from August to November 2016. This study indicated that; the regression of length against weight was computed from the relationship W= a Lb; growth coefficient (b) value 2.880 ±0.430 less than 3, which indicate have negative allometric growth. The condition factors (K) is 3.866 ± 0.027; While the sex ratio was (M: F) 1:0.98.

Keywords:
Allometric growth, fulton factor, Nile tilapia, the regression coefficient.
