An experiment was
conducted to compare the growth and economics of producing
Clarias gariepinus in ponds (6.4x5.4x1.5m3)
and tanks (2.5x1.1x1.2m3) for 56days. Fingerlings
of Clarias gariepinus (mean weight, 1.80g and body
length, 4.40cm) were stocked at 250 and 50fish separately into each pond and tank in
duplicates. Fish were fed a commercial feed containing 45%
crude protein at 5% body weight. It was divided into two
halves and fed at 1000 and 1600hours daily. At final
harvest, the total yield of fish was significantly greater
(P<0.05) in pond, 3.0kg than those in tank, 1.81kg. There
was no significant difference (P>0.05) in mean weight gain
condition factor (0.92+0.03, 0.91+0.03)
and feed conversion ratio (0.56+0.01, 0.51+0.01)
between fingerlings stocked in pond and tank. Fish in pond
had higher percentage weight gain and specific growth rate
while survival rate ranged 74.11+0.54-88.80+0.54%
in the culture media. Net profits obtained were
N4300(pond) and N2250(tank). The benefit: cost ratio was higher for
tank (1.38) than for pond (1.19). The pond environment
appeared more productive while the tank was more economical
with higher benefit in this study.
