The result shows the mean accuracy of classification rate is up to 95.41% for freshwater plankton images, such as chironomid larvae, cyclops and harpacticoida.

通过对红虫、剑水蚤、猛水蚤样本进行分类试验证明，平均识别准确率达到95.41%，验证了该方法的有效性。

In copepod, Thermocyclops taihokuensis and Mesocyclops thermocyclopoides were dominant, and their average lengths were 730μm and 680μm, respectively. Nauplii and cyclopoid copepodites also had high abundance and biomass.

桡足类优势种为台湾温剑水蚤和温中剑水蚤，平均体长介于680~730μm之间，此外，无节幼体和剑水蚤幼体在数量和生物量上也比较高。

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。

Then the dominant species of each season was identified and the contribution of the abundance of these dominant species to total abundance was analyzed. The results indicate an obvious succession of dominant species. Centropages dorsispinatus, Acartia pacifica ca and Sagitta enflata were the primary dominant species in summer, however, Paracalanus aculeatus, Acartia pacifica and Paracalanus crassirostris were the major dominant species in autumn.

结果表明，两个季节优势种具有明显更替现象，夏季（6月）主要优势种为背针胸刺水蚤、太平洋纺锤水蚤和肥胖箭虫；秋季（9月）主要优势种是针刺拟哲水蚤、太平洋纺锤水蚤和强额拟哲水蚤。

"Daphnia:any of various water fleas of the genus Daphnia, some species of which are commonly used as food for aquarium fish."

&水蚤：水蚤科中的一种水蚤属水生跳蚤，其中的一些种类通常用作水族馆鱼类的食物。&

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。

It was also observed that the malpighian tube of Daphnia magna is the more sensitive than the other organs. The present study indicate that the embryo development test with target organ effected rate were more sensitive than traditional acute toxicity test. Suggest that the method may be apply in environmental toxicants evaluation.

透过大水蚤各标的器官之生长试验比较，可明确观察出试验药剂对大水蚤生长及器官之影响，比传统水蚤稚虫急毒性试验对於药剂可以有更深入的解释，可实际应用於环境中的毒物侦测。

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。
