ABSTRACT: This study focused on the supplementation of
four-sided spice fruit powder (Tetrapleura
tetraptera) on some zootechnical performances of juveniles of Clarias gariepinus and was carried out
from February 14 to July 20 at the Massoma Fish Farm of Bojongo Mbeidi located
in the Littoral Region, Department of Wouri, Douala IV district. The farm
benefits from a climate favorable to aquaculture activity. For this purpose,
five (5) treatments were tested including T0+ (imported feed), T0-,
T0.3, T0.4, and T0.5 respectively for the treatments with 0% supplemented food; 0.3%; 0.4% and 0.5%
of Tetrapleura tetraptera powder. A total of 450 Clarias gariepinus fry with an initial average weight of 7 ± 1.5 g, were distributed in happas of
0.49 m2 each placed in Triplicate in a completely randomized device.
Four isoprotein foods with 38% crude protein were formulated to feed these fry
at 7% of their biomass per day for 15 days then to their fullness until the end
of the experiment. Intermediate fishing was carried out every fortnight. 75
days later, the results recorded show that the highest average survival rate
(96.44% ± 3.5%) was recorded with the subjects fed feed supplemented with 0.4% T. tetraptera powder. The
average weight (120.93 ± 67.20), weight gain (113.93 ± 67.20), specific growth
rate (3.64 ± 0.79% g/d) and total lengths and standard (26.43 ± 1.9 and 23.66 ±
1.76) the highest were recorded with the T0+ treatment (imported
feed). The highest conditioning factor K (2.14 ± 0.15) was recorded with the
treatment supplemented with 0.4% T. tetraptera. The lowest conversion ratio (1.28) was
recorded with the treatment fed with imported blue crown food (T0+).
Furthermore, the lowest production cost was recorded with the treatment
supplemented with 0.4% T. tetraptera.
It appears from this study that the juveniles of C. gariepinus better value the feed substituted with 0.4% of the
powder of four sides (Tetrapleura tetraptera).
