| Abstract: | Some aspects of the reproductive biology of the Nile tilapia,
Oreochromis niloticus population in the Nyanza Gulf of lake Victoria,
Kenya were investigated from March to August 1991. The overall sex
ratio was 2.08:1 in favour of males. A variation in sex ratio was
observed with females predominating over males in lengths between 37.5
and 41.0 cm total length. Fecundity ranged from 864 to 6316 eggs with
an average of 2141. The relationship between fecundity (F), and total
length (L) and weight (W) was F=22.755 L super(1.2141); F=177.142 W
super(0.342). The fecundity was compared to that reported elsewhere
and together with spawning habits, were suggested as some of that
factors contributing to the abundance of the Nile tilapia over other
tilapiine fish species in Lake Victoria. |
