Abstract: One of the contemporary problems faced in aquaculture is the
provision of adequate nutritive and cheap feed to reduce the cost of fish production.
In this study, the efficacy of Musa sapietum Inflorescence (MSI) as an
ingredient in the diet of the juveniles of African mud catfish, Clarias gariepinus
was evaluated over a 90 days growth period. About 3 experimental diets were
formulated at 0 (control), 10 and 15% inclusion levels of MSI. The nutrient
composition of MSI, growth performance and survival rate of the juvenile fish,
feed intake and water quality parameters were determined using standard procedures.
The results showed that MSI had a moisture content of 94.90% in the DM fat represented
2.08% and crude protein 1.85 %. MSI was a good source of potassium (24755 ppm
of DM), calcium (9804 ppm in DM), sodium (8824 ppm in DM) and magnesium (3529
ppm in DM) but low in phosphorous (106 ppm in DM). There were no statistical
differences found (p>0.05) in the specific growth rate, feed conversion and
protein efficiency ratio of the juvenile fish fed with the banana blossom inclusions
in comparison to the control. The 15% flower meal inclusion resulted in the
highest fish survival rate (70%) compared to 63.3% (10% inclusion) and 60% (control).
There were no significant differences (p>0.05) in the feed intake by the
fish raised with 10 and 15% inclusions of MSI (34 and 33%, respectively) in
comparison to the control that yielded 33%. There were no significant differences
in the mean water pollution rates by nitrite accumulation (0.000, 0.275 and
0.042 mg dL-1 in 15, 10 and 0% inclusions, respectively) and total
dissolved solids (32, 35 and 33% in 15, 10 and 0% inclusions, respectively).
The results obtained in this study indicated that M. sapietum flowers
which are locally available in the rural areas and inexpensive have the potential
to partially replace the expensive animal protein required in feed formulation
and thus reduce cost in fish farming.
