Abstract

A four week feeding trial was carried out in a recycling water sytem to investigate
the effect of restricted feeding regimes on compensatory growth and body
composition in African catfish, Clarias gariepinus . A fishmeal-based diet containing
35% protein and 18 kJ g-1 gross energy (GE) was fed to triplicate groups
of 30 fish. Fish were fed in five feeding schedules of 28 days : restricted 14 days
+ appetite 14 days; restricted 7 days + appetite 7 days; restricted 3 days + appetite
4 days; restricted 2 days + appetite 2 days. The restricted regime was achieved
by feeding at the rate of 1% (maintenance ration) of their body weight per day,
adjuted after weekly weighing. African catfish did not exhibit compansatory
growth response under alternating periods of a feed restriction and appetite
feeding. However, not sifnificant (P>0.05) values of feed and protein utilization
were found under alternating periods of feed restriction and appetite feeding.
Significantly higher (P<0.05) feed intake was observed in treatment with appetite
throughout than those in other treatments. All the feeding schedules showed
no significant differences (P>0.05) on body composition, organ indices, eviscerated
carcass composition, viscera lipid and liver lipid. This study reveals that
C. gariepinus failed to display compensatory growth response by alternating
periods of restricted and appetite feeding.
