浮游动物

The results show that they fee d on a variety of prey items, and tend to eat Calanoida, Brachyura Zoea larva, H arpacticoida and Nauplius.

结果表明黄鳍刺虎鱼前期幼鱼为浮游动物食性，主要摄食镖蚤类、短尾类幼体、猛蚤类和甲壳类的六肢幼体。

The effects of immobilized microbes including Rhodospirillaceae, Bacillus, Nitrobacteria and denitrifying bacteria on the changes in species, quantity and biomass of algae and zooplankton in aquiculture water and on the physicochemical environmental factors, such as nitrogen, were studied.

研究了固定化微生物(含有光合细菌、芽胞杆菌、硝化细菌以及反硝化细菌)对养殖水体中藻类和浮游动物的种类、数量、生物量以及水体氮素等理化环境的影响。

The range of sound pressure measurements was 0.15–105 Pa. A series of consecutive measurements were made at intervals of 52.5 s. The wavelength of 80 kHz frequency, although not ideal for investigating mesozooplankton, was chosen because we were initially studying patchiness of

健全的压力测量范围为0.15-105宾夕法尼亚州的连续测量了一系列在52.5秒的时间间隔作出80千赫频率的波长，虽然不是理想的调查浮游动物，是因为我们选择了最初的研究斑块

Long-term outcomes for the planktonic abundance of these three phyla are different, however.

然而这三种浮游动物丰度的长期观测结果却是不同的。

The results of this study confirmed the importance of large zooplankton grazing and revegetation with submerged macrophytes for the maintenance of the clear-water state and restoration success in hypereutrophic ponds.

这个研究的结果证实大型浮游动物的牧食和沉水植被的重建对清水期的维持和富营养化池塘的成功修复作用重大。

In all zooplanktons, the site-occurrence-rates of Copepoda and Chaetognatha were the highest, 100% and 93.3%, and the average biomass of which were 298.56 mg·m-3 and 118.09 mg·m-3 and the summation accounted for 96.88% of total biomass. The result shows that these two species created a strong relationship with the distribution of saury fishing grounds, and their biomass can be considered as the important indicator of looking for the main saury fishing grounds.

在浮游动物中，桡足类和箭虫类占绝对优势，出现频率分别达到100%和93.3%，平均每立方米生物量为298.56 mg和118.09 mg，其和占总生物量的高达96.88%，严重影响了总生物量的空间分布，分析认为与中心渔场分布的关系最为显著，因此可将其生物量大小作为确定秋刀鱼中心渔场的重要指标。

If it really exists difference in food quality of seston, the difference can be recognized from the variation of fatty acid compositon in higher trophic level organisms.

当悬浮颗粒物在时空上存在数量和质量差异时，这种差异就可能在浮游动物中体现出来，而且通过脂肪酸的信息可以追踪到这种差异。

For small ponds the seasonal dynamics of zooplankton community structure are relatively unstudied, as are any mechanisms underlying these dynamics.

就小型池塘浮游动物群体结构的季节性动力学研究是相对少的，例如这些动力学中潜在的一些机制。

It eats fishes, zoa plankton, and jellyfish.

它以鱼、浮游动物和水母为食。

In the periods of peak zooplankton abundance,228. that is

在浮游动物数量激增的高峰期，234。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
