本文指出栉孔扇贝干贝氨基酸含量较高,次于虾夷扇贝,高于海湾扇贝。其氨基酸的含量与个体大小成反比。在软体部中以闭壳肌的氨基酸含量最高:闭壳肌的平滑肌的氨基酸含量高于横纹肌。从分析栉孔扇贝的17种氨基酸中以谷氨酸含量最高。栉孔扇贝外套膜和内脏块均含有相当量的氨基酸,可加以利用  相似文献

万山水域温盐分析：海湾扇贝养殖环境可行性研究   总被引：2，自引：0，他引：2  

卢婉娴  梁小云 《台湾海峡》1996,15(1):1-5

对初步建成的《养殖水域温盐信息系统》进行试验开发，分析了海湾扇贝南移至万山水域养成的可行性。根据万山湾18a每日的温盐信息，通过平均值、距平值、极限值等多项统计特性的分析，认为珠江口水域只有10月至翌年4月基本具备养成海湾扇贝的温盐自然条件，盐度20～35；温度18～28℃。而每年6～8月该水域都会受高温、低盐的袭击，盐度极端低值曾出现2．39、3．06、4．80等，在这样的盐度条件下，会导致海湾扇贝养殖成体全部死亡。因此，本着因地制宜的方针，作者认为该水域不宜发展海湾扇贝养殖。  相似文献

The phylogeny of native and exotic scallops cultured in China based on 16S rDNA sequences     

刘保忠  董波  相建海  王在照 《中国海洋湖沼学报》2007,25(1):85-90

Scallops of the Family Pectinidae are a valuable resource in marine industry of the world. Understanding the phylogeny of the family is important for the development of the industry. In this study, partial 16S mitochondrial rDNA genes were obtained from 8 scallop species that are commonly cultured indigenous and transplanted species in China. Phylogenetic relationships of Pectinidae were analyzed based on the 8 sequences and other 5 published ones in GenBank, representing 9 genera of the family. The molecular phylogeny trees were constructed using 3 methods with software PHYLIP. The results showe that total 13 species of scallops clustered in 4 clades. Pecten maximus joins P. jacobaeus then Amusium pleuronectes in cluster, indicating close relationship of genus Amusium with Pecten in evolution. P. yessoensis is close to Chlamysfarreri and C. islandica. No enough material was available to single out genus Patinopecten as an independent monophyletic subfamily. The position ofAdamussium colbecki indicates that it is far from genus Pecten but near to genus Chlamys in evolution.  相似文献   

Development of 101 Novel EST-Derived Single Nucleotide Polymor- phism Markers for Zhikong Scallop （Chlamysfarren）

Zhikong scallop （Chlamys farreri） is an important maricultured species in China. Many researches on this species, such as population genetics and QTL fine-mapping, need a large number of molecular markers. In this study, based on the ex- pressed sequence tags （EST）, a total of 300 putative single nucleotide polymorphisms （SNPs） were selected and validated using high resolution melting （HRM） technology with unlabeled probe. Of them, 101 （33.7%） were found to be polymorphic in 48 indi- viduals from 4 populations. Further evaluation with 48 individuals from Qingdao population showed that all the polymorphic loci had two alleles with the minor allele frequency ranged from 0.046 to 0.500. The observed and expected heterozygosities ranged from 0.000 to 0.925 and from 0.089 to 0.505, respectively. Fifteen loci deviated significantly from Hardy-Weinberg equilibrium and significant linkage disequilibrate was detected in one pair of markers. BLASTx gave significant hits for 72 of the 101 poly- morphic SNP- containing ESTs. Thirty four polymorphic SNP loci were predicted to be non-synonymous substitutions as they caused either the change of codons （33 SNPs） or pretermination of translation （1 SNP）. The markers developed can be used for the population studies and genetic improvement on Zhikong scallop.  相似文献

Several polyculture models of scallopChlamys farreri and kelpLaminaria japonica currently employed in Sungo Bay and other parts of northern China are described in this paper. Economic benefits of different polyculture models are analysed based on the growth rate, culture density and market price. In addition, site selection, critical environmental conditions and polyculture problems are discussed in detail. This project was funded by the International Development and Research Centre (IDRC), Canada, and the National Committee of Science and Technology of China.  相似文献
