A 120-day feeding trial was conducted to determine growth, feeding efficiency,
and biochemical composition of juvenile spotted babylon Babylonia areolata
(initial mean weight of 1.48 ± 0.06 g) fed on conventional trash fish and a formulated
moist diet in a flow-through grow-out system. The snails readily accepted the formulated
moist diet and showed good growth and survival during the trial. There were no significant
differences in specific growth rate, feeding efficiency, and survival between the
snails fed on trash fish or the formulated moist diet. At the end of the experiment,
biochemical analysis of the snail flesh showed significant differences in flesh quality, with
the snails fed on trash fish having a significantly higher crude protein compared to those
fed on the formulated diet, but there was little difference in crude lipid content. Whole
body tissue of snails fed on trash fish had significantly higher total amino acid, essential
amino acid, and non-essential amino acid levels compared to those fed the formulated
diet. This study showed that the formulated moist diet can be readily used for B. areolata
growout for maximizing growth, survival, and feeding efficiency; however, further
research is needed to improve the flesh quality particularly amino acid and fatty acid
levels before its suitability for B. areolata is assured.
