1 Introduction Coilia ectenes is an important commercial fisheries species, and its production has declined dramatically in recent years.Its necessary to investigate the microsatellite genetic information for further resource conservation and development of management strategies of this species.In this study, we developed thirty-four novel polymorphic microsatellite markers isolated from C.ectenes using the combined biotin capture method.The polymorphism of each locus was further assessed in 30 individuals from Dandong,estuary of Yalujiang River.

采用扫描电镜和免疫组化技术,研究了尼罗罗非鱼(Oreochromis niloticus)鳃中氯细胞的分布,及其不同盐度(0‰,10‰,20‰,30‰)胁迫对氯细胞数目和形态变化的影响.扫描电镜结果显示,氯细胞分布在鳃丝的鳃小片基部,根据其表面开口长度,可分为3种亚型:Ⅰ型(>6.5 μm)、Ⅱ型(3.2-6.5μm)和Ⅲ型(<3.2 μm).不同盐度下氯细胞总数目变化趋势为10‰<0‰ <20‰
Onchidiidae are shell-less pulmonate gastropods, a group ofeuthyneuran gastropods found in the sea, brackish water, fresh water and on land.Systematics of the group is in a state of confusion, and the
Anodonta woodiana is a filter-feeding bivalve species, which lives in shallow river beds in China.Since the fishery of the species has become an important economic resource in South China, it is inter
Supercritical carbon dioxide (SC-CO2) extraction was used to determine the volatile composition of Antarctic krill (Euphausia superba).The optimal extraction conditions for the oils yield within the e
Hepcidin抗菌肽是由生物肝脏细胞表达的一类具有抗菌作用的碱性小分子肽,它们在机体免疫系统中发挥了重要作用,被认为是抗生素的理想替代品.不同来源的Hepcidin分子中均存在8个高度保守的半胱氨酸残基,它们与Hepcidin的抗菌活性有关.本文参考已经报道的斑点叉尾鮰(Ictalurus punctatus)hepcidin全长cDNA序列,通过RT-PCR首次从其肝脏中克隆了编码hepcid
本研究采用16SrRNA基因克隆文库法、分离培养分子鉴定法两种方法对中华绒螯蟹(Eriocheir sinensis)肠道微生物展开研究,旨在全面揭示中华绒螯蟹肠道菌群组成与结构.克隆文库结果表明,变形菌门(Proteobacteria)、拟杆菌门(Bacteroidetes)和厚壁菌门(Firmicutes)为中华绒螯蟹肠道内主要菌群,其中弓形杆菌属(Arcobacter)、Marinifilu
本文通过对人工养殖大鲵肌肉和皮肤营养成分进行分析,旨在为人工养殖大鲵资源的综合开发利用提供科学的理论指导.结果表明:人工养殖大鲵肌肉中蛋白质含量高,蛋白质氨基酸组成全面、呈味氨基酸含量高、必需氨基酸含量符合FAO/WHO理想模式,基本无限制性氨基酸,是质量较好的优质蛋白质,且蛋白质质量明显优于大鲵皮肤蛋白质.大鲵皮肤中的第一限制性氨基酸为色氨酸,第二限制性氨基酸为亮氨酸,大鲵皮肤中含硫氨基酸含量丰
Protein is the basis of life.Using the X-ray diffraction technique to determine the three dimensional structure of proteins has a significant meaning to help understanding the life process and the gui
近年来我国冷库建设数量增长很快,但是如何实现冷库中流场的均匀性是保证冷库今后使用质量的关键.本文采用了Simple算法,结合波兴涅克(Boussineq)假设,对冷藏库内的气流组织进行了三维模拟,并用试验加以验证,得出了利用非结构网格模拟的结果和试验结果吻合性更好,并比较了三维、二维方法对冷库内气流分布模拟的准确性,研究发现三维方法对冷库气流场的模拟更准确可靠,并得到了冷库竖直和水平平面上的气流分
本文根据2000~2007年我国大型拖网渔船的渔业生产数据,结合表层、50m、100m水层盐度和温度等环境数据,利用偏最小二乘法(partial least-squares regression,PLS)探讨环境因子与智利竹筴鱼渔场关系.研究认为,智利竹筴鱼渔汛旺期为6-9月,最适盐度范围为33.6~33.7.9月份盐度分布范围显著小于其他月份.表层、50米水层最适温度主要是13~14℃,100米
