Abstact: Fingerling C. gariepinus of mean weight 3.0g were stocked 20 fish per trough in a mini flow-through
system consisting of fifteen troughs and fed diets containing 0%, 25%, 50%, 75%, 100% of garden snails as
replacement for fish meal for 42 days. Each treatment was replicated thrice. It was observed that garden snails were
better utilized than fish meal as the fish fed 25% garden snail had a superior growth to the control. There was no
significant difference (P.0>05) in the mean weight gain, food conversion ratio, specific growth rate, gross feed
conversion efficiency and condition factor of fish fed the varying levels of garden snail. The fish fed 75% garden
snail had a lower growth as a result of mortality. It is suggested that 25% garden snails can be efficiently utilized in
C. gariepinus diets. This study also showed that the protein quality of garden snails compares well with that of fish
meal. [Report and Opinion. 2010; 2(1):58-62]. (ISSN: 1553-9873).
