Abstract

Feeding experiment conducted to determine the protein requirement of red
tilapia (Oreochromis niloticus) revealed a significantly (P<0.01) higher weight
gain when fed with 35% protein diet than those with 25 and 30% protein, irrespective
of the protein sources used. Weight gain of fish fed with 40% dietary
protein did not differ significantly (P>0.01) from those fed with 35% protein.
However, the feed conversion efficiency and protein efficiency ratio of the animals
fed with 35 and 40% protein diet varied significantly (P<0.01) revealing
the optimum protein requirement of red tilapia in the range of 35-40%. While
fish fed with fishmeal based diets recorded good survival rate at all protein
levels, ensilage based feeds recorded poor survival rate at lower protein levels
viz. 25 and 30%. On the basis of specific growth rate, feed conversion efficiency
and protein conversion ratio, fish ensilage based diets were on par with that of
fishmeal based diets, suggesting fish ensilage as an alternative source of protein
in the feeds of red tilapia
