9402971 Bowen This project will quantify genetic variation and evolutionary relationships within the Clupeoid genera Sardinops and Engraulis. These two taxa, commonly known as sardines and anchovies, are pelagic filter feeders typically found in warm-temperate coastal waters and have great commercial importance. The taxonomic and systematic distinctions between regional forms of these two genera remains unresolved despite the intense interest in means by which these fish have been dispersed throughout the ocean. This study will use mtDNA geneologies to elucidate the pattern of colonization among regional forms. A second goal of this study will be to estimate mtDNA clonal diversity within regional forms of Sardinops and Engraulis. Finally, mtDNA data will be used to assess the level of gene flow among putative sardine stocks along the west coast of North America. These results have strong implications for fishery assessment, as reproductive populations are the fundamental units of species management.

9402971 Bowen这个项目将量化骨骼属Sardinops和Engraulis内的遗传变异和进化关系。 这两个分类单元，通常称为沙丁鱼和凤尾鱼，是通常在温暖的沿海水域中发现的上层过滤器喂食器，并且具有极大的商业意义。 尽管这两个属的区域形式之间的分类学和系统区别仍然无法解决，尽管对这些鱼被分散在整个海洋中的手段感兴趣。 这项研究将使用mtDNA基因学来阐明区域形式之间的定殖模式。 这项研究的第二个目标将是估计sardinops和Engraulis区域形式的mtDNA克隆多样性。 最后，MTDNA数据将用于评估北美西海岸推定的沙丁鱼股票之间的基因流量水平。 这些结果对渔业评估具有很大的影响，因为生殖种群是物种管理的基本单位。
