Nilnaj Chaitanawisuti, Anutr Kritsanapuntu, 1998. Growth and survival of hatchery-reared juvenile spotted Babylon, Babylonia areolata Link 1807 (Neogastropoda: Buccinidae), in four nursery culture conditions. Journal of Shellfish Research. 17(1):85-8.
Abstract Growth and survival of hatchery-reared juvenile spotted babylon, Babylonia areolata, were assessed for 7 mo. Juveniles with initial mean shell length of 15.0 ± 0.8 mm (n = 25) were held in a nursery culture system with four different treatments: two substrate types and two seawater flow rates. Length and weight measurements of individual babylon were determined monthly among the four experimental treatments, and the average monthly growth was evaluated. There were significant differences in both shell and tissue growth rates among the four treatments in most months (p < 0.05). The highest growth rates occurred in the treatment with sand substrate and flow-through seawater, whereas the lowest growth was in the treatment with no sand substrate and static seawater. The juveniles exhibited no growth reduction in any of the treatments except the treatment with no sand substrate and static seawater. Survival exceeded 80% for all treatments.
