中华哲水蚤

通过对比北大西洋的飞马哲水蚤，作者认为，黄海陆架区中华哲水蚤所积累的油脂很可能是种群休眠时期的重要能量来源。

After comparison to the data on Calanus finmarchicus in North Atlantic , we concluded that the oil storage of Calanus sinicus might be the main energy resource during dominant stage .

实验结果表明，随着重金属离子暴露时间的延长，中华哲水蚤T-SOD活性变化显著。

The results showed that the SOD activity changed markedly with prolonged exposure of these ions .

Hg2+和pb2+对中华哲水蚤T-SOD活性的影响均表现为随暴露时间延长，呈先上升后下降的趋势。

Effects of Hg2 + and Pb2 + on the SOD activity were increased first and then decreased during prolonging the exposure time .

结果表明，中华哲水蚤对浮游植物的选择性摄食具有食物密度依赖性。

The results showed that the selective feeding behavior of C. sinicus was dependent on food density .

10月，中华哲水蚤在冷水团边缘潮汐锋区的繁殖、种群补充活跃，或许可以解释秋、冬季近岸种群的恢复。

In October , the reproduction and recruitment in the tidal front areas were active , which might explain the recovery of the nearshore population in autumn-winter .

低浮游植物细胞丰度下中华哲水蚤具有明显的选择性摄食行为，高浮游植物细胞丰度下中华哲水蚤摄食选择性由偏好转变为排斥，浮游植物细胞丰度329cells.ml-1是中华哲水蚤由偏好趋于排斥摄食的阈值。

It had an obvious food selectivity when the abundance of phytoplankton cell was low , but the selectivity changed from preference to discrimination at high phytoplankton cell abundance , with a threshold value of 329 cells · ml-1.The selective feeding of C.

浮游动物群落多样度、均匀度和丰富度低，优势度大，中华哲水蚤是主要优势种，群落结构不稳定；

The quantity and diversity of diatom decreased , and the dominant species of diatom changed . The index of diversity , evenness and richness of zooplankton were low , which indicated that the community structure of zooplankton in this area was not stable .
