Abstract
A six-week experiment was conducted in
six glass aquaria to study the feed conversion ratio (FCR) of
Cirrhinus
mrigala fingerlings fed on cotton seed meal (35.69% CP), fish meal
(50.41% CP) and barley (9.98% CP). The ingredients were supplied at the rate of
4% of wet body weight of fingerlings twice a day. Twenty fingerlings were
randomly stocked in each aquarium. The Cirrhinus mrigala fingerlings
gained highest average body weight on fish meal (1.23g), followed by cotton seed
meal (1.17g) and barley (0.55g). FCR calculated for three treatments was highest
for barley (2.59), followed be fish meal (2.02) and cotton seed meal (1.55). The
correlation coefficient between average body weight and FCR values was
significant and positive in case of cotton seed meal and fish meal, whereas it
was positive and non significant in case of barley.
