在过去的十年里，象牙壳已被成功地开发为中国南方重要的水产养殖生物。本研究测定了方斑东风螺和B的壳长和体重的年生长量。lutosa（CBL）的象牙壳。a B的中国人群。areolata和B. Lutosa和泰国种群B。研究了方孔板。我们用Mallows的C-p准则和三个增长统计模型来解释和预测B的增长模式。areolata和B. lutosa。结果表明，在恒定的环境条件和相同的人工养殖管理制度下，养殖初期不同群体间的壳长和体重差异不显著（P > 0.05）。随着生长周期的延长，CBL的生长曲线呈下降趋势，而TBA和CBA的生长曲线则相反。使用LevengergMarquardt迭代估计，CBA、TBA和CBL在逻辑模型中壳长的渐近增长分别为42.479、47.300和41.031 mm。在Brody模型中，CBA、TBA和CBL的渐近体重分别为20.890、25.142和19.575 g。研究结果可为B的养殖项目制定或养殖管理提供参考。areolata和B. lutosa。
Over the past decade, the ivory shells have been successfully exploited as important aquaculture organisms in Southern China. In this research, we measured the annual growth of shell length and body weight of two species including Babylonia areolata and B. lutosa (CBL) of ivory shells. a Chinese populations of B. areolata and B. lutosa, and a Thai population of B. areolata were studied. We used Mallows' C-p criterion and three growth statistics models to explain and predict the growth pattern of B. areolata and B. lutosa. The results showed that under constant environmental conditions and the same artificial culture management regime, shell length and body weight did not differ significantly (P > 0.05) between populations in initial cultural stage. However, the significant differences were found with an extension of the growth cycle; Notably, the growth curve of CBL body weight showed a decreasing tendency in the high temperature season, but the TBA and CBA growth patterns were reversed. The asymptotic growth of shell length in the logistic model, estimated using the LevengergMarquardt iteration, was 42.479, 47.300 and 41.031 mm for CBA, TBA and CBL, respectively. The asymptotic body weight in the Brody model was 20.890, 25.142 and 19.575 g for CBA, TBA and CBL, respectively. The results provide reference for breeding project and formulation or aquaculture management of B. areolata and B. lutosa.
