Three Species of Bomolochus Claus, 1864 (Copepoda: Bomolochidae) Parasitic on Marine Fishes of Taiwan

于台湾海水鱼体上的三种属于盗鱼蚤科，盗鱼蚤属(Bomolochus Claus， 1864)的寄生桡足类

Copepoda was dominant group in zooplankton of the Changjiang Estuary. The abundance of them overwhelming dominated all zooplankton.

三、桡足类是长江河口浮游动物中的优势类群，其数量分别在枯、丰水期浮游动物总数量中占绝对优势。

From Chaotianmen to Zigui,the Shannon-Weaver diversity index of phytoplankton changes undeely.4 the impact of sediment deposition on zooplankton in the waters studiedAccording to the results of the experiment, we had learnt that the species composition of zooplankton sampled had the same tendence-the species was from less to more, and the biomass was also gradually increasing. Particularly Copepoda had increased significantly in the type and quantity. The main of zooplankton at each sampling situs were protozoa and rotifers.

朝天门江段到秭归江段的浮游植物的Shannon-Weaver多样性指数呈波浪式变化，整体有下降趋势。4研究水域泥沙沉降对浮游动物的影响从本次实验的结果来看，四次采样浮游动物种类组成都有同一个趋势：种类由少到多，生物量也逐渐增大，特别是桡足类在种类和数量上都增加明显，各采样点的浮游动物以原生动物和轮虫为主。

Low community variability was also observed in the late season for rotifers when fish were excluded and, as a result, they were exposed to high invertebrate predation from cyclopoid copepods.

后期的季节中轮虫的低群体多变性也被观察当鱼类被排除在外，结果，它们被暴露于来自桡足类高无脊椎动物掠食行为

Thrissakarnrnalensis was the basal pelagic phytoplankton feeder,while Trachurus japouicu was commonly feed in seagrass circumstance.GC/C-IRMS analysis was applied to fish,zooplankton and demersal species.

建立GC/C-IRMS技术测定生物体单分子脂肪酸碳稳定同位素的方法，应用于长江口毗邻海域主要生物种类带鱼、小黄鱼、黄鲫等海洋鱼类，桡足类、箭虫、水母等浮游动物，中国毛虾、周氏新对虾、中华管鞭虾等底栖生物的研究。

Fry feed on nymphal and larval insects while in fresh water, but once at sea may not feed at all until they become juveniles, when they eat copepods and other zooplankton.

在新鲜的水中，但一旦在海上可能不饲料，直至他们吃桡足类和其他浮游动物时，他们变得青少年，鱼苗喂若虫和幼虫昆虫。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
