1994年夏季（8月）和1995年冬季（2月）在台湾海峡北部用肠荧光技术对两种优势浮游桡足类，亚强真哲水蚤（Eucalanus subcrassus）和中华哲水蚤（Calanus sinicus）的摄食强度、摄食习性做了定性和定量的追踪研究。主要结果如下：（1）亚强真哲水蚤和中华哲水蚤的肠色素（GPC）水平分别为0.131～7.634和0.067～1.932μg/ind。表现出种间个体大小，食性的差别和显著的季节差异。（2）连续站24小时追踪调查表明：两种桡足类的GPC周日变华呈相似的昼夜双峰型，夜间和午间摄食显著加强；这种变化与潮汐周期有较好的吻合。（3）亚强真哲水蚤和中年哲水蚤的肠排空过程用色素衰减法测行：亚强真哲水蚤：GPC=0.497exp（-0.020t）；中华哲水蚤：GPC=7.214exp（-0.033t）。求午此两种类的肠排空速率分别为0.020/min和0.33/min。（4）亚强真哲水蚤和中华哲水蚤的日食量分别为0.6和5.4μg/ind，比重日食量为0.7%和5%碳体重：两个桡足类种群对浮游植物的摄食压力分别是0.1%～0.6%和1.5%～3.1%现存量，对应0.2%～0.6%和26.8%～53.7%初级产量。文章对典型亚热带海区浮游桡足类摄食的几个生态牲和台湾海峡中型浮游动物摄食作用微弱的现象作了分析和讨论。

The distribution and abundance of viable resting eggs of copepod Acartia pacifica in Xiamen Bay, China, were determined in the laboratory by the presence of nauplii hatched from the sediments. Sediment cores to a depth of 30cm, sliced at 1.0cm intervals, showed that most viable resting eggs of A. pacifica occurred near the sediment surface (0-5cm), and the number of viable eggs sharply decreased with depth of the sediment, although resting eggs remained viable as deep as 23cm. 210Pb analyses of the sediments indicated that the maximum age of viable eggs of A. pacifica was 20.5 years and the mean egg age was 4.3 years. The egg mortality of A. pacifica in the sediment was 0.1408 year-1, or 85.92% annual egg survival, calculated by regressing ln (egg density) on the age of the sediment. The horizontal distribution of viable resting eggs ranged from 2.27×103 to 3.85×105m-2, with a mean value of 9.49×104m-2. Regressions between viable eggs of A. pacifica and all fine-fraction particle size classes (at 2μm intervals) were not significant. The accumulation of viable resting eggs that can persist for an extended period of time provided evidence for the existence of an egg bank of A. pacifica in the seabed of Xiamen Bay.

在近岩河口区浮游生物群落生态的物质转换与能量流动过程中，同属多种并存的桡足类起着重李的作用，它们占据着异质的时空，并导致了摄食生态灶的差异[1]。新近研究不表明，在北温带沿（近）岩水域，浮游桡足类可以生产滞育卵，以适应其生活周期中不利的环境条件。Marcus [2] 还证实滞育卵的生产主要受温度和日光照期的变化所诱导，而其休眠维持与终了则受温度的影响。不过，较低纬度区的浮游桡足类足否也能生产滞育卵，报道尚不多[3]。李少菁等[4，5]已对厦门港九龙江河口海区歪水蚤的卵型及孵化率作了初步研究。本文报道这一海区的歪水蚤数量的季节变化，滞充卵的生产与孵化及其对温度的反应。

The carbon and nitrogen budgets were estimated on the adult females, juveniles and post furcilia larvae of Pseudeuphausia sinica fed on newly hatching nauplii of Artemia salina in the laboratory. It was found that the ingestion rate was linearly related to the food concentration, suggesting high feeding potential. The linear correlation could be established between the respirating rate (carbon consumption rate) and carbon ingestion rate, as well as carbon assimilation rate. The regression coefficients (i.e. specific dynamic action coefficients) were in the range from 9% to 16% (ingested C) or 10% to 17% (assimilated C) respectively, with lower in the post-furcilia larvae. There also existed a linear correlation equation between estimated total nitrogen excretion rate and the rates of nitrogen ingestion and assimilation separately, except for the juveniles. The defecation rates increased with the increase of the ingestion rate; as a result, assimilation efficiency was not related to the ingestion rate, ranging from 0.84 to 0.95. The results inducated that the nitrogen content in food particles was a key factor limiting the growth of P. sinica. The critical ingestion rate was 10p.gN

In June and November 1988 samples were collected by the improved Manta neuston net at 18 stations in the soutbem Taiwan Strait. One hundred and two species and variations of phytoneuston are identified. Total individuals of phytoneuston in June are more than those in November. The horizontal distribution of phytoneuston is that the dense area occurs in the southern Taiwan Bank in June, while it appears in the western Taiwan Bank in November. The diel variations of phytoneuston are very obvions. The maximum abundance of phytoneuston occurs in the afternoon (16:00), and the minimum at midnight which is opposite to zconeuston. The relationships between phytoneuston and environment, and between phytoneuston and zooneuston are also discussed.
