flow-trough FRP tanks with 100 1water were used. From the study it was found that<br />
the diet containing freshwater fish waste, snail and chicken liver as non-conventional<br />
protein sources gave statistically on par (p>0.05) results in terns <strong>of</strong> growth and nutrient<br />
utilization when coihpared to diets containing different conventional protein sources<br />
such as mussel meal, chicken liver, squid meal and prawn meal (Table 37). The study.<br />
results suggests the possibility <strong>of</strong> use <strong>of</strong> freshwater fish waste, snail and chicken liver<br />
as non-conventional protein sources in developing the nutritionally balanced costeffective<br />
practical diets <strong>of</strong> sword tail fingerlings.<br />
