Chaitanawisuti, N., Kritsanapuntu, A., Natsukari, Y., & Kathinmai, S (2001) 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 Abstract 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%
