dc.description.abstract |
Nile tilapia (Oreochromis niloticus) fingerlings were reared in earthen ponds at three different feeding frequencies; twice
daily, twice after 1 day, and twice after 2 days for a period of 7 months. Three hundred and seventy five fish were stocked into each of
the nine, 150 m2
ponds with three replicates for each treatment. The fish were fed with a commercial diet (26% crude protein).
Significantly (P < 0.05) best percentage weight gain (3479.59 ± 116.63% ) and specific growth rate (SGR) (1.65 ± 0.02%) was observed
in groups of fish fed daily compared to fish fed after 1 day and after 2 days which recorded SGR of 1.62 and 1.59% respectively. The
lowest feed conversion ratio (1.04 ± 0.01) was observed in fish fed twice after 2 days. The highest survival (83.24%) was recorded in fish
fed daily and there were no significant differences among the other feeding groups (P > 0.05). Partial enterprise budget analysis
indicated that feeding O. niloticus twice after 2 days in fertilized ponds is significantly profitable (P < 0.05) than feeding twice daily and
after 1 day. Thus it is possible to rear O. niloticus in fertilized earthen ponds when fish are fed twice after 2 days. |
