中文摘要:
      于2007年9月,对选育的菲律宾蛤仔不同壳色品系(C:对照组;Tr:两道红品系;Tw:两道白品系;Ab:玛瑙黑品系;Or:海洋红品系;Pw:珍珠白品系;Z:斑马蛤品系;W:波纹蛤品系)F1和F2的表型性状进行了研究。结果表明,1龄F1的壳长以Pw最大,与Tr差异不显著(P>0.05),明显大于对照组及其它品系,Z壳长最小且与其它品系差异显著((P<0.05),C的壳长明显小于Tw、Ab((P<0.05),但与Or、W差异不显著((P>0.05);F1鲜重也以Pw最大,Z最小,且与其它品系差异显著(P<0.05),Tr、Tw、Ab和Or鲜重差异不显著((P>0.05),但明显大于C((P<0.05);F1产卵量Pw、Tr明显高于其它品系,Z、C明显小于其它品系((P>0.05),Tw、Ab、Or和W彼此差异不显著((P>0.05);F2的表型性状,C的孵化率低于其它品系((P<0.05),但与Tw无显著差异((P>0.05),各壳色品系间卵径、受精率和D形幼虫大小差异不显著((P>0.05)。浮游期结束时(9日龄),W与Z幼虫壳长明显大于其它品系((P<0.05),Tw、Ab、Or、Pw、Z彼此间差异不显著((P>0.05);幼虫存活率大小顺序为,Ab、Z>Or、W>Tw、Pw >Tr>C,彼此差异显著((P<0.05)。变态时间和变态规格各品系间无显著差异((P>0.05),变态率大小的顺序为Ab>Z>Tw>Or>Pw>W>Tr>C,彼此差异显著((P<0.05)。室内培育阶段结束时(240日龄),Ab壳长最大,但与Or、Tr差异不显著,Z壳长最小,但与C、W差异不显著((P>0.05),C与Pw、W,Tr、Tw、Or之间,以及Tw与Pw差异也不显著;Z的存活率最高,明显高于除Ab外的其它品系,C的存活率最低,明显低于除Tr、Tw外的其它品系,W>Or>Pw,彼此差异显著((P<0.05)。360日龄时,Pw壳长和鲜重最大,显著大于其它壳色品系((P<0.05),Ab和Z壳长和鲜重显著小于其它壳色品系((P<0.05);Ab和Z的存活率高于其它品系((P<0.05),但与Or、Pw差异不显著((P>0.05),Or存活率高于C((P<0.05),其它各品系存活率无显著差异((P>0.05)。从相对产量上看,Z(678.63%±56.80%)>Ab(554.88%±69.42%)>Or(527.23%±76.21%)>W(475.97%±90.25%)>Pw(405.90%±55.19%)>Tw(224.89%±47.85%)>Tr(178.50%±34.50%)>C(100.00%±22.10%)。
英文摘要:
      The study on phenotypic traits of different shell color strains F1 and F2 (C:the control strains; Tr; two band red strain; Tw:two band white strain; Ab:agate black strain; Or:ocean red strain; Pw:pearl white strain; Z:zebra strain; W:wave strain.)of Manila clam was conducted in September 2007.The results showed that the shell length of Pw F1 was the greatet,and significantly greater than others except Tr (P<0.05),the shell length of Z was the smallest,and significantly smaller than others(P<0.05),there were no obvious differences in shell length among C,Or,W,between Tr and Tw,among Tw,Ab,Or,among Ab,Or,W(P<0.05).Both fresh weight and fecundity of Pw F1 were the greatet,that of Tr were the second greatet and significantly greater than others(P<0.05),those of Z were the smallest,and significantly smaller than others(P<0.05),there were no remarkable differences between C and W,among Tw,Ab,Or in fresh weight and between C and Z,among Tr,Ab,Or,W in fecundity(P<0.05).No significant differences in egg diameter,the fertilized rates and size of D larvae were observed among all strains(P<0.05),the hatching rate of C was significantly lower than those of other strains except Tw(P<0.05).By end of pelagic period(9 d),the shell lengths of W and Z were significantly greater than those of other strains(P<0.05),there were no remarkable differences in shell length among Tw,Ab,Or,Pw,Z,W(P>0.05); the sequences of survival rates were following:Ab,Z>Or,W>Tw,Pw>Tr>C,there were significant differences among them(P<0.05).No remarkable difference in both metamorphic time and metamorphic size among all strains was observed(P >0.05).There were such a sequence in metamorphic rates as follows:Ab>Z>Tw >Or>Pw>W>Tr>C,there were significant differences among them(P<0.05).By the end of indoor rearing period(240 d),the shell length of Ab were significantly greater than those of other strains except Or,Tr(P<0.05),the shell length of Z were significantly smaller than those of other strains except C,W(P<0.05),there were no remarkable differences in shell length between C and Pw,W,Tr,Tw,Or,and between Tw and Pw; the survival rate of Z was remarkably higher than those of other strains except Ab(P<0.05),the survival rate of C was remarkably lower than those of other strains except Tr,Tw(P<0.05).On day 360,both shell length and fresh weight were the greatet and remarkably greater than those of other strains(P<0.05),the shell length of Ab and Z were significantly smaller than those of other strains(P<0.05),the survival rate of Ab and Z were significantly higher than those of other strains except Or,Pw(P<0.05),the survival rate of Or was significantly higher than that of C(P<0.05),there was no remarkable difference in survival rate among other strains(P<0.05).The order of relative yields was as follows:Z(678.63%±56.80%)>Ab(554.88%±69.42%)>Or(527.23%±76.21%)>W(475.97%±90.25%)>Pw(405.90%±55.19%)>Tw(224.89%±47.85%)>Tr(178.50%±34.50%)>C(100.00%±22.10%).
