A small crustacean of the order Amphipoda, such as the beach flea, having a laterally compressed body with no carapace.

异脚类，端足目动物异脚类的一种小甲壳纲动物，如滨海的水蚤，体侧扁，无甲壳

Any of various aquatic crustaceans of the subclass Branchiopoda, such as the fairy shrimp and water flea, characterized by a segmented body and flattened, leaflike thoracic appendages.

鳃足动物一种鳃足亚纲水生甲壳类动物，如神仙虾和水蚤，特征是身体分节，具有平直叶状的胸腹附属结构

鳃足动物一种鳃足亚纲水生甲壳类动物，如神仙虾和水蚤，特征是身体分节，具有平直叶状的胸腹附属结构

Dominant species were comprised of mainly micro- and meso-zooplankton species and planktonic larvae of benthos such as Parvocalanus crassirostris, Cirripedia nauplius, Oithona attenuata, Acrocalanus gibber, Nauplius, Bivalvia veliger, Copepodite, Oithona simplex and so on.

优势种主要是中小型种类和底栖动物的幼虫，如强额孔雀哲水蚤、蔓足类无节幼虫、细长腹剑水蚤、驼背隆哲水蚤、无节幼虫、双壳类面盘幼虫、桡足幼体、简长腹剑水蚤等。

Nutrient-enriched reservoirs support greater abundance and biomass of copepods. However, dominance of Calanoids was lower while dominance of cyclopoids, copepodids and nauplius were much higher in the nutrient-enriched reservoirs.

随着水库营养水平的升高，桡足类密度和生物量也相应增加，但是大型哲水蚤的优势度降低，而剑水蚤和桡足类幼体的优势度上升。

In addition, a kind of copepoda was experimentally cultured, which from the resting eggs separated from the pond mud, then the cultural conditions and biological characters were partly mastered.

分离池塘底泥中桡足类的休眠卵，进行孵化并培养，初步掌握了其中一种桡足类(克氏纺锤水蚤Acartia clausi)的培养条件和部分生物学特性，并进行了纯化培养，为进一步研究病毒传播途径提供充足的实验材料。

Adult Cyclops, with body length of one to several millimeters, may be caught by naked eye to bring consumers unsanitary sense and may become disease transmission medium as the host of pathogenic parasite, like schistosome and eelworm, to threaten human health. So Cyclops needed be effectively removed to ensure drinking water security.

剑水蚤类浮游动物在用户水中出现，不仅违反了生活饮用水卫生标准中对感官性状指标的规定，给用户带来了不良的感官影响（剑水蚤体长可达1～几个mm，肉眼可见），容易引起用户对水质信心的下降与恐慌，更为重要的是大多数剑水蚤是诸如血吸虫、线虫等水中致病生物的中间宿主，从而成为传播疾病的一个重要媒介，给人们的用水安全问题带来了很大的威胁。

Water fleas are not insects but copepods, a crustacean like lobsters and crabs but extremely small.

水蚤不是昆虫类动物，而是桡脚类动物，是一种象龙虾或蟹一类的，但体形非常的小。

Biomass of M. micrura and C. vicinus increased with increased trophic level of the lake water, while biomass of large-bodied cladocerans (D. galeata and Leptordora kindti) decreased with increased fish predation, and relative abundance of calanoids to cyclopoids tended to decrease with increased fish predation.

微型裸腹溞与近邻剑水蚤的优势度随水体营养水平的上升而上升，而大型枝角类（盔型透明溞与透明薄皮溞）的优势度随水体中鱼类捕食压力的上升而下降，哲水蚤相对于剑水蚤的优势趋向于随鱼类捕食压力的上升而下降。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
