Effects of feeding rates on the growth, survival and feed utilization of hatchery‐
reared juvenile spotted babylon Babylonia areolata Link 1807 in a flowthrough
seawater system. Aquaculture research, 32(9), 689-692.
The effects of feeding levels on the growth, survival and feed utilization of
hatchery‐reared juvenile Babylonia areolata Link 1807 were assessed at four daily
rations of 3%, 5%, 10% and 15% of body weight. Three duplicated groups of
juveniles (mean initial body weight 0.26
± 0.3 g) were stocked into indoor
rearing tanks supplied with a flowthrough system of ambient natural seawater for
150 days. Growth in body weight differed significantly (P
0.05) among the
various feeding levels. Final body weight of individual snails increased with
increased feeding ration at a particular ration level. Meanwhile, increasing the daily
ration to 10% and 15% significantly improved growth and feed utilization
efficiency. The food conversion ratios (FCRs) for the 3% and 5% feeding levels
were significantly lower than those for the other feeding levels. Final survival was
best at feeding levels of 10% and 15% of body weight, ranging between 96.9% and
97.3%, but was very poor at the 3% and 5% feeding levels, ranging from only
49.5% to 54.8%.
