Abstract

In the experiment conducted in laboratory for a period of 45 days to evaluate
the effect of selected dietary protein levels (30%, 35%, 40%, 50%,
60%) on survival, growth, conversion efficiency and protein efficiency ratio in the
fry of the mullet Liza macrolepis, using purified diets, the high protein levels 40%
to 60% gave better results on survival rate (69% to 87%). Maximum gain in
length and relative growth (56.6%) was at 40% protein level. However, low conversion
efficiency (2.41 and high protein efficiency ratio (1.388) were at 30%
protein diet. The maximum body proteins in the fish coincided with 35% protein
diet and 40% protein diet and the minimum body protein was at 30% protein diet
and again at 60% protein diet.
Although the minimum conversion efficiency and maximum protein efficiency
ratios were observed at 30% protein level, data on survival, growth and body
protein content indicate that for the fry of Liza macrolepis the optimum protein
level in the diet is 40%.
