Days later,in order to find out the influence of the immune polysaccharide on the growth rate and disease-resistance of the Eriocheri sinensis, the weight of the Eriocheri sinensis were monitored and the experimental were challenged with the histoplasmin of diseased Eriocheri sinensis.
结果表明,在中华绒螯蟹的饲料中添加每千克蟹体重400.0mg至1200.0mg的免疫多糖,对中华绒螯蟹的生长速度和身体颜色等没有显著影响;能有效地增强供试中华绒螯蟹的抗病力,与对照组相比,经口服攻毒后投喂不同剂量免疫多糖试验组的中华绒螯蟹有效率为52.4%~66.77%,而经注射攻毒后各试验组中华绒螯蟹的有效率为39.2%~49.9%,口服攻毒后的有效率稍高可能与病原体的感染方式有关。

Morphological differences among two Eriocheir japonicus populations collected from Suifen River and Hepu River and two Eriocheir sinensis populations from Changjiang and Liaohe River were studied based on cluster analyzing and discriminal analyzing on 17 morphological characters , and the hybrids of Eriocheir sinensis× Eriocheir japonicus was also researched as an assistant subject.
选取合浦水系和绥芬河水系的日本绒螯蟹与长江水系和辽河水系的中华绒螯蟹4个绒螯蟹种群,以辽河水系绒螯蟹与绥芬河水系绒螯蟹杂交后代为辅助研究对象,对它们的17个外部形态特征分别进行聚类和判别分析。

Topological structure of the molecular phylogenetic tree, constructed by 16S rRNA gene with Neighbor-Joining method, revealed that all species of Helice from Sesarmidae and two species of Hemigrapsus from Varunidae were clustered into one branch, two species of Sesarma from Sesarmidae were clustered into another one, Grapsus albolineatus from Grapsidae and Plagusia tuberculata from Plagusiidae were formed one absolute branch respectively. The molecular analysis showed that the genus Helice indeed must be considered to be Varunidae, because it formed a monophyletic group with the genus Hemigrapsus yet not the Sesarmidae.
而采用NJ法构建的系统进化树的拓扑结构也显示,所有的厚蟹与属于弓蟹科的肉球近方蟹和绒螯近方蟹聚为一支;属于相手蟹科的2种相手蟹聚为一支;属于方蟹科的白纹方蟹和属于斜纹蟹科的瘤突斜纹蟹又各自成为一支。

The phylogenetic analysis of these two nonmarine crabs together with intertidal, supratidal and swimming crabs based on portions of mitochondrial 16S rDNA sequences suggested that Grapsioidea, Ocypodoidea, Potamoidea and Portunoidea arose from a common marine ancestor, and the estimated divergence time are similar.
基于线粒体16S rDNA部分序列,对这2个类型的非海洋蟹类与潮间带蟹类、海洋蟹类之间的系统发生分析提示,方蟹总科、沙蟹总科、溪蟹总科和梭子蟹总科的蟹类起源于一个共同的海洋蟹类祖先,它们彼此之间的歧异时间基本一致。

First we investigated the relationship between the female pleonal expansion and female reproductive condition (i.e., non-ovigerous, ovigerous, or with spermatophores) to clarify the morphological characteristics of female coconut crabs that were able to mate.
首先,我们调查了雌蟹腹变宽和生殖条件的关系(非抱卵蟹、抱卵蟹、或者纳精囊中出现精荚)来确认椰子蟹具有交配能力的雌蟹形态特征。

Results We discovered and confirmed that there were 17 different species of 1st intermediate host of in Paragonimus Jiangxi, covering 2 families and 3 genera, and 23 different species of 2nd intermediate host, covering 1 order, 1 family and 3 genera, 15 of which were reported to be new species by the authors. Furthermore, a new genus of Jiangxi Huananpotamon was built up, based on the assumption that Wuyi mountain range is the developing centre of Huananpotamon , and tend to spread out towards Jiulian mountain of Nanling mountain range adjacent to Guangdong Province and Luoxiao mountain range next to Hunan Province. In addition, Jiangxi Province freshwater crab order was created at the end of research, as well as a complete classification and retrieval table of its order and genus. The authors also proved that the advantageous stocks of freshwater crabs carrying encysted metacercaria of Jiangxi Paragonimus westermani were Sinopotamon fukiense and S.wanzaiense .
结果 江西卫氏并殖吸虫第一中间宿主淡水螺种或媒介共计17种,隶属2科3属;第二中间宿主淡水溪蟹种或媒介为23种,隶属1总科1科3属,其中15种为作者等研究发现报告的新种;建立了江西并殖吸虫媒介新属——华南溪蟹属,认为武夷山脉是华南溪蟹属类群的分化中心,并有向与广东毗邻的南岭山脉的九连山和与湖南接壤的罗霄山脉扩展的趋势;建立了江西省淡水蟹类总科及科与属的分类检索表;证实携带江西卫氏并殖吸虫囊蚴的淡水溪蟹优势种群为福建华溪蟹、万载华溪蟹
