中文摘要:2006年4月,从湛江流沙港马氏珠母贝(Pinctada martensii)养殖群体挑选黑色、红色、黄色和白色壳色马氏珠母贝个体为亲本建立建立黑色、红色、黄色和白色壳色选系F1。分别在受精后第8天、14天和21天,从4个壳色系随机各取样50个幼虫,测量每个个体的壳长与壳高,并利用方差分析比较4个壳色系的生长差异。结果表明,实验期间4个壳色系的平均壳长和壳高存在显著的差异(P<0.05)。在第8天、14天和21天,黑壳色系具有最大的平均壳长,分别为(105.77±6.47)μm、(132.20±13.48)μm和(198.17±22.61)μm;白壳色系具有最小的平均壳长,分别为(94.35±4.29)μm、(120.13±10.50)μm和(178.25±19.61)μm。在第8天、14天和21天,黑壳色系具有最大的平均壳高,分别为(99.47±6.22)μm、(126.83±9.87)μm和(187.73±7.54)μm;第8天和21天,白壳色系具有最小的平均壳高,分别为(87.33±5.02)μm和(172.70±13.78)μm;在第14天,黄壳色系具有最小的平均壳高(112.40±9.84)μm。本结果初步说明在幼虫阶段马氏珠母贝壳色和生长性状可能存在着一定的相关性。本研究旨在为马氏珠母贝的壳色系列进一步选育提供基础依据。

外文摘要:In April 2006, the black, red, yellow and white shell color lines of pearl oyster Pinctada martensii were established by separately selecting black, red, yellow and white shell color breeders in Liusha stock, Zhanjiang of Guangdong. On days 8, 14 and 21,50 individuals were randomly sampled from each of the four shell color lines and shell length and shell height of each individual were measured. Analysis of variances was conducted to evaluate growth differences among the four shell color lines. Significant differences were found in growth among the four shell color lines at each sampling time (P〈0.05). On days 8, 14 and 21, the black shell color line had the largest shell lengthes of (105.77±6.47)μm, (132.20± 13.48)μm and (198.17±22.61)μm, while the white shell color line displayed the smallest shell length with values of (94.35 ± 4.29)μm, (120.13 ± 10.50) μm and (178.25±19.61)μm; on days 8, 14 and 21, the black shell color line had the largest mean shell heights, with values of (99.47 ± 6.22) μm, (126.83 ± 9.87) μm and (187.73 ± 7.54) μm, respectively. On days 8 and 21, the white shell color line had the smallest mean shell heights, with values of (87.33 ± 5.02) μm and (172.70 ± 13.78) μm, respectively. On day 14, the yellow shell line had the smallest mean shell height of (112.40 ± 9.84) μm. The present results indicate there may exists an relationship between shell colors and larval growth of pearl oyster P. martensii. [Journal of Fishery Sciences of China, 2008, 15 (3) : 488-492]
