Similarly, results showed an increasing trend of seed output per
spawn (Fig. 2)with the increased feeding rate in the case of stunted
broodfish (S). But the trend in normal (N) or non-stunted group
was quadratic; increased from 1%, peaked at 2% and declined at
3%. The lowest level (1%) of feeding rate was proved to be too
low to support the reproduction in stunted (S) tilapia whereas
feeding rate of 3% biomass per day resulted in increasingly higher
production. However, there was no significant difference
(PN0.05) in the number of eggs per g of female when compared
between two broodfish groups and among all the feeding rates.
The percentage feed conversion to seed (g of seed/g of feed⁎100)
decreased with the increase in feeding rate (Fig. 3). However, there
was no significant difference between the two fish groups.
