查询词典 fiddler crab

This paper analysed the amino acid composition in larval mud crab, Scylla serrata,from zoea I to megalopa, and their diets, rotifer and nauplii of Artemia. An essential amino acid index was employed to evaluate the nutritive value of the protein source in diets.

本文分析测定了锯缘青蟹幼体从刚孵化至大眼幼体各发育阶段及其饵料轮虫和卤虫无节幼体的氨基酸组成，并使用必需氨基酸指数来评价饵料蛋白质的质量。

During the raising fry period,466 000 tails of Zoea were bred up to 101 100 megalopa and 51 400 crab larvas, the survival rate 21.7% and 11.6% respectively.

整个育苗共投放蚤状幼体46.6万尾，培育出大眼幼体10.11万只，成活率为21.7%，培育成仔蟹苗5.14万只，育苗成活率为11.6%。

The living time of crabs in low temprature was longer than that in high temprature, however, it is more longer in high salinity than in low salinity. For pH, the alkalic environment is more propitious to the livability of crab than acid environment.

对于温度而言，低温下幼蟹的存活时间较长；对于盐度而言，高盐度逆境比低盐度逆境下的存活时间长；对于pH 值而言，碱性环境下的存活时间比酸性环境下的存活时间长。

The main food items also varied monthly, and changed from small-sized to relative large-sized species. The main diet composition included polychaeta and crab in May, fish and amphipoda in June, fish and polychaeta in July, empty stomach in August, and fish and shrimp in September.

主要饵料生物组成有明显的月变化，且食物个体有逐渐增大的趋势，其中5月主食多毛类和蟹类，6月主食鱼类和端足类，7月为鱼类和多毛类，8月样本较少且为空胃，9月为鱼类和虾类。

The results showed that the juvenile A. sinensis mainly fed on demersal fish, polychaeta and amphipoda, as well as some small-sized benthic invertebrates including shrimp, crab and bivalve.

结果表明：长江口中华鲟幼鱼以底栖小型鱼类、多毛类和端足类为主要食物，兼食虾类、蟹类及瓣鳃类等小型底栖动物。

This research will provide reference basis for exploring the cause and pathogenesis of infertility and aphoria with Crab-eating Macaque as animal model.

结论］该研究为采用食蟹猴作为动物模型探讨不孕不育的病因和发病机理提供参考依据。

While testing on mRNA transcripts of either SCY2 or scygonadin,respectively in bacterially challenged mud crab,it was found that there was no significant change of SCY2 and scygonadin mRNA abundance in all of the tested tissues,suggesting that bacterial infection can not induce the transcription of both SCY2 and scygonadin genes.

检测细菌感染条件下锯缘青蟹各组织SCY2及Scygonadin表达情况，发现在感染后48 h内，SCY2和Scygonadin mRNA在性腺组织中的表达水平均无明显变化，说明外部细菌感染不是SCY2的直接诱导表达因素。

These are about 10% of the know species of Crab - scientists call them Brachyura, which means "short tail".

这是约10％的知道螃蟹-科学家称之为短尾，意思是&短尾巴&。
