Such as silver carp, bighead carp fry to eat the plankton, mostly in the upper heart water activities; grass, herring fry eat a large Cladocera and benthic organisms, mostly in shallow water edge of the activities.

如鲢、鳙的夏花吃浮游生物，多在水体中心上层活动；草、青鱼的夏花吃大型枝角类和底栖生物，多在水体边的浅处活动。

60 Species of zooplankton were identified, among which there were Rotifera 34 species, Copepoda 13 species, Cladocera 6 species, among which Rotifera has an dominance for 55.02%, especially Brachionus sp.

浮游动物共鉴定到60种，其中轮虫有34种，桡足类13种，枝角类有6种。

Both of amount of 54 ind/L and 95 ind/L were found from cladocera of 8 species as well as Copepoda of 6 species and their proportion of 28.57% and 21.43% were recorded.

浮游动物28个种属，其中轮虫14个种属，数量137 ind/L，占50%；枝角类8个种属，数量54 ind/L，占28.57%；桡足类6个种属，数量95 ind/L，占21.43%。

The biomass of zooplankton changed relatively intensely, especially Cladocera、Copepoda and Young animal, and the biomass of the zooplankton will gradually increase.

随着泥沙的逐渐沉降，浮游动物生物量变化相对激烈，尤其是枝角类、桡足类和无节幼体，水中浮游动物生物量将逐渐增加。

The mean density and biomass of cladocera are 0.070 ind/L and 0.002 mg/L. The mean density and biomass of copepoda are 5.155 ind/L and 0.021 mg/L. 5. Attached algae were classified into 3 Phylum 16 Genus 27 Species.

枝角类的平均密度为0.070 ind／L，平均生物量为0.002 mg／L；桡足类的平均密度为5.155 ind／L，平均生物量为0.021mg／L。

Temporal changes in zooplankton composition occurred in both ponds with Cladocera appearing in abundance later, in the fourth week, whereas copepods and rotifers were well represented since the beginning.

浮游动物组成短暂的变化在两个塘同时出现随着枝角类较晚出现一定丰度，在第四周左右，然而桡足类和轮虫自开始就出现。

Adaptability of plankton to the salinity, alkalinity and pH value, fishery exploitation of biological resources in inland saline waters and use of halophiles or salt tolerant freshwater cladocera as live food for marine fish larvae were discussed.

此外，还讨论了浮游生物对盐度、碱度和pH的适应性、内陆盐水生物资源的渔业利用以及利用盐水或耐盐性淡水枝角类作为海水鱼苗活饵料的前景。

Five water sampling collected from Miyun Reservoir were observed quantitatively. Thirty-six species of zooplankton including 11 protozoan, 15 rotifers,6 cladocero and 4 copepoda were found. The results showed the eutrophicational feature, such as lower biodiversity ,miniaturization and more amount.

浮游动物共检出4门，30属，36种；浮游动物群落具有原生动物数量多，轮虫次之，枝角类与桡足类量少的特点，呈现出浮游动物数量大、小型化、多样性低等伴随水体富营养化出现的特征。

Branchlets, petioles, and abaxial veins pilose; petals not corniculate; seeds obtriangular, surface with ribs.

小枝，叶柄和背轴静脉具柔毛；花瓣不具小角状突起；种子倒三角形，装以面具棱。

Branchlets not obviously angled; leaf blade small, 5-10 × 2.5-5 cm, narrowly elongate; sepals imbricate; disk cupulate.

小枝而不是明显具角；叶片小， 5-10 * 2.5-5 厘米，狭拉长；萼片覆瓦状；花盘杯状。 1 C。 paniculatus 灯油藤

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
