ABSTRACT
The study focused on the production of
Clarias gariepinus fingerlings produced from Clarias gariepinus broodstock fed
inclusion levels of Azanza garckeana. Clarias gariepinus broodstock fed
different inclusion levels (0, 5, 10, 15 and 20%) of Azanza garckeana pulp
meal, representing diet 1, 2, 3, 4 and 5 in a randomised complete design. The
result showed that fish fed with 20% A. garckeana had the highest oocyte and
significantly different (p<0.05) from fish fed other diets. 10% inclusion
level had the highest percentage hatchability (98%) followed by 5% (96%), 15%
(92%), 20% (76%) and the least 0% (62%). At the end of the experiment highest
survival of fingerlings were in inclusion levels 5% and 10%. The best cost
benefit ratio (CBR) and profit was in 10% inclusion (0.60 and N2, 441), followed by 5% inclusion (0.47
and N2, 060.22), 15% inclusion (0.35
and N1, 746.52), 0% and 20% had
negative CBR and profit.
