Abstract:

The effects of
four practical diets (3 commercial and one locally prepared)
on growth, feed utilization and survival of catfish hybrid (Heterobranchus
longifilis
 x
Clarias gariepinus) fingerlings were compared in
plastic aquaria in triplicates for 56days. Diets differed in
crude protein (CP) and digestible energy as follows:
Commercial Diet 1 (39.73% CP, 3911.8Kcal/kg), Diet 2 (34.50%
CP, 3926.8Kcal/kg), Diet 3 (45.37%, 3883.6Kcal/kg) and local
Diet 4 (40.34% CP, 3861.8Kcal/kg). Observations made
indicated higher performance in weight and percent weight
gain (2.299g, 411%), specific growth rate (0.78% day-1),
condition factor (0.96), feed conversion ratio (2.67) and
protein efficiency ratio (10.73) for fingerlings fed Diet 3
than other diets. Commercial Diet 2 appeared to perform
least among the test diets. Fish survival was high and
varied between 76.7% (Diet 4) and 96.7% (Diet 1). These
results demonstrated that catfish hybrid fingerlings can be
successfully reared in aquaria with good feed conversion,
growth and high survival on commercially or locally prepared
diets with 45.37% CP and adequate energy.
