Abstract
121 words
The study on the effect of dietary protein, lipid and 11 –
Ketotestosterone (11 – KT) levels on the progeny quality of
Oreochromis andersonii broodstock will be conducted at
National Aquaculture Research and Development Centre, Kitwe,
Zambia. Factorial experiments will be set in order to investigate
the effect of lipid (5%, 10% and 15%) and protein (20%, 30%,
and 40%) from soybeans on the reproduction of O. andersonii.
Furthermore, effect of 11 – KT (30, 60 and 90mg/kg of feed)
will be investigated on progeny quality, sex ratios and hormone
degradation. Optimal lipid, protein and 11 – KT levels that can
be incorporated into the broodstock and fry diets of O.
andersonii will be known by the end of the study.
