浮游生物

Chlorococcales An order of Chlorophyta that contains singlecelled and colonial algae that lack undulipodia, e. g. Chlorella, Volvox, found in freshwater plankton and most terrestrial habitats.

色球藻目：绿藻门中的一目包含单细胞和群居的藻类，它们都缺乏波动足，例如小球藻 Chlorella 和团藻 Volvox ，在淡水中的浮游生物和大多数的陆地上栖息。

The algal species of the Cyanophyta such as Chroococcus, Dactylococcopsis, Phormidium and Spirulina were all euryhaline algae.

并就浮游生物在对虾养殖中的重要作用进行了分析。

It is understood that artificial breeding jellyfish demanding on the environment, sea water temperature to be in the 15 ℃ to 35 ℃ between; jellyfish 1 mm below the main feeding of the rotifers, Cladocera and other natural food organisms, called the clear water, abundant plankton.

据了解，海蜇人工养殖对环境的要求较高，海水温度需在15℃至35℃之间；海蜇主要摄食1毫米以下的轮虫、枝角类等天然饵料生物，因此要求水体清澈，有丰富的浮游生物。

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。

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。

The complexly branched arms of the basket sea star, or starfish, catch plankton for the echinoderm.

复杂的枝状的肢臂的篮子海星，或海星，捕捉浮游生物给棘皮动物。

The plankton of estuary play an important role in material and energy flowing of estuarine ecosystem.

The comparative experiments of rearing Penaeus vanname larvae fed the microencapsulated diets and micro-partical diets of "OK" brand and a searies of microgranular diets of "Bonasse" brand was performed. Two brands of diets are respectively formulated with rotifera at percentage of 70%, 80%, 90% and 100%. During the nursery period, the water quality factors such as the concentrations of NH3-Nt, NH3-Nm, NO2-- N, COD and main planktons were tested to find out their change regulation and the influence on survival rates and metamorphic rates of shrimp larvae.

本文利用欧开牌微胶囊饲料、微粒饲料和博尚牌系列微型饲料作为对虾育苗饲料，分别以70％、80％、90％和100％的比例与卤虫活饵料配合来培育凡纳对虾幼体，通过对凡纳对虾幼体有关生长发育指标的对比以及对育苗期间水中总氨氮(NH_3-N_t)、非离子氨氮(NH_3-Nm)、亚硝酸盐氮(NP_2~--N)、化学耗氧量和主要浮游生物等水质因子进行检测，找出它们的变化规律并比较上述饲料对幼体生长发育、成活率、变态率和育苗效果的影响。

Artemia, Cyclops, and Mysis are all recommended as supplementary foods that will help bring the females into breeding condition.
