中文摘要：为考察大珠母贝驯化子二代的生长性能,以大珠母贝海南三亚群体为亲本,将经过连续两代驯化养殖培育的子二代放入网袋吊养在雷州半岛徐闻县承梧村海区(N 20°34′07″,E 109°90′98″)开展了养殖试验,定期监测养殖海区的环境指标(水温、溶解氧、盐度和叶绿素a),测量大珠母贝的生长性状,并利用标准贝塔朗菲模型、逻辑斯谛模型、冈珀茨模型和特殊贝塔朗菲模型分别拟合大珠母贝驯化子二代的生长性状。试验结果显示:大珠母贝壳高和壳长的绝对增长率呈极显著正相关(r=0.918,P=0.001)。大珠母贝壳高的绝对增长率与水体叶绿素a质量浓度呈显著正相关(r=0.763,P=0.028);壳长的绝对增长率与水体叶绿素a质量浓度呈正相关(r=0.559,P=0.150)。大珠母贝壳高、壳长绝对增长率与水体溶解氧质量浓度均呈正相关(r=0.296,P=0.477;r=0.338,P=0.413),与水温呈负相关(r=-0.282,P=-0.498;r=-0.275,P=0.509)。大珠母贝生长性状获得的标准贝塔朗菲模型、逻辑斯谛模型、冈珀茨模型与特殊贝塔朗菲模型拟合度r 2均大于0.930,其中标准贝塔朗菲模型更适合用于拟合大珠母贝子二代的壳高(r 2=0.962)和壳长(r 2=0.956)的生长。试验结果为大珠母贝的健康养殖和优良品种选育提供了理论参考。

外文摘要：In order to investigate the growth performance of the second generation of pearl oyster Pinctada maxima after selective breeding,the second generation of the pearl oyster bred by the parents in Sanya,Hainan Province and cultivated for two consecutive generations of domestication were put into net bags and cultured in the sea area of Chengwu Village,Xuwen County,Leizhou Peninsula(N 20°34′07″,E 109°90′98″),the environmental indicators(water temperature,dissolved oxygen,salinity and chlorophyll a concentration)were regularly monitored in the culture area,and the growth traits of the pearl oyster were measured.Growth models were constructed using General Von Bertalanffy,Logistic,Gompertz,and Special Von Bertalanffy models.Results showed that there were positive correlations between shell height and length absolute growth rate(r=0.918,P=0.001),and between absolute growth rate and water column chlorophyll a content(r=0.763,P=0.028).There was positive correlation(r=0.559,P=0.150)between the water column chlorophyll a concentration and the absolute growth rate of shell length.The absolute growth rates of shell length and shell height were inversely connected with water temperature indicators(r=-0.282,P=0.498;r=-0.275,P=0.509)and favorably correlated with indicators of dissolved oxygen in the water(r=0.296,P=0.477;r=0.338,P=0.413).The General Von Bertalanffy model was found to be best fitted the growth traits,with R-squared values exceeding 0.930 for all models,and particularly suited shell height(r 2=0.962)and length(r 2=0.956)increases in the second filial generation.The finding offers theoretical references for healthy cultivation and selective breeding of P.maxima,contributing to the advancement of pearl culture practices.
