| 摘 要： | 2005年-2007年对紫贻贝和厚壳贻贝种间进行了杂交生产性试验，通过亲贝强化培育、确认雌雄亲贝、改革育苗水体交换方法、投喂混合单细胞藻类、流水培养附着稚贝等技术，获得F1代。结果表明，各试验组生长特性，正交F1代﹥紫贻贝﹥厚壳贻贝﹥反交F1代。其中正交F1代获附着稚贝3.77亿粒，平均壳长为1.13 mm、平均壳高为0.78 mm，育苗成活率达35.57%。正交F1除在孵化率上低于紫贻贝、厚壳贻贝外，在壳长、壳高、成活率等方面指标具有一定杂交优势，而反交F1代的杂交优势不明显。

| Abstract: | Abstract: Studies on hybridization between Mytilus.galloprovincialis and Mytilus coruscus and pilot-scale breeding were carried out from 2005 to 2007. F1 were obtained with technologies of intensive culture of parental mussel, identification of male and female, amelioration of waterbodies exchange of breeding, feeding compound tiny algae, et at. The results show that the growth characters are positive cross F1 > M..galloprovincialis > M.coruscus> negative cross F1. 377 million juvenile mussels of positive cross F1 with shell length of 1.13mm, shell height of 0.78mm were obtained. The survival ratio reaches 37%. Advantages of positive cross F1 exist in shell length, shell height, survival ratio, when compared with M.galloprovincialis and M. coruscus. But the hatching rate is lower. No obvious advantages were found in negative cross F1. |
