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。

Compared to planktonic bacteria,sessile bacteria are even more harmful and the methods for their determination are even more complicated.

与浮游菌相比，固着菌的危害更大，检测方法更复杂，真正有效的固着菌的杀菌剂必须具有较强的剥离作用和穿透能力。

When PO3-4-P concentrations exceeded 0.010mg·L-1, the TAPA was significant difference (P＜0.01).②The contents of APA in phytoplankton, bacteria and dissolved were different. The ratio of DAPA to TAPA was the highest and BAPA was the smallest.

水体中的碱性磷酸酶在不同粒级组分中的分布差异明显，其中以溶解性碱性磷酸酶活性所占的比例最大，浮游植物体中的碱性磷酸酶活性所占的比例次之，细菌体中的碱性磷酸酶活性所占的比例最小。

At the same time, to strengthen the quality supervision and management, factory now has to match the various types of precision instruments, more than 80 sets / Desk: HPLC, IR, UV, planktonic bacteria detector, particle detector, such as dust, and with accounting 10% of the total number of quality inspection, quality monitors, so factory can produce all kinds of quality levels of products, to meet the requirements of a variety of customers.

同时，为加强质量的监督管理，本厂现拥有与之相匹配的各类精密仪器80多套/台：HPLC、红外、紫外、浮游菌检测仪、尘埃粒子检测仪等，并且配备占总人数的10%质量检验、质量监督员，所以，本厂能生产出各种的质量级别的产品，能满足各类客户的要求。

It is one of the apex non-pelagic predators (along with Giant Trevally, Napoleon Wrasse, and Large Groupers) of its range (from the Marshall islands to the Indian Ocean).

Micrura and C. vicinus, were related to increased trophic level of the lake water.

浮游甲壳动物群落体长的上升由优势种体长的上升所导致，其中微型裸腹溞与近邻剑水蚤体长的上升与水体营养水平的上升关系密切。

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。
