| Comparative and regression analysis of length-weight relationship of Oreochromis niloticus (Linneaus, 1785) for a period of six months from October 2020 to March 2021, Nile River, Bubungu, Eastern region, Uganda, East Africa, (0°23'31.92"N 33°13'51.95"E) (Fig 1). The slope value (b) estimated for O. niloticus of both sexes was found to be 3.4171. The regression equations derived for both sexes was estimated Log W=3.4171+0.1772 Log L. In spite of the fact that O. niloticus predetermined well in the wild collection of fish, there was a good statistical difference in their health and general wellbeing. The correlation coefficient was found to be (p<0.01). The significant difference between sexes of the species "F" value was at 1% level. The b value differed from the ideal cube law of "3" as is with the case of LWR studied in this region. The slope value was compared to Indo-Pacific regions. |
