摘要

1. 1. Different stages of the mesopelagic copepod, Gaussia princeps, collected from different areas of the Pacific Ocean had wax esters as the principal lipid class (49–72% of the lipid). 2. 2. During the first seven days of starvation only triglycerides (12–18% of the lipid) were used followed by slower depletion of wax ester stores. Following 60 days starvation the lipid decreased from 1·6 to 0·4 mg per individual with 1·0 mg of this decrease due to wax ester utilization. Thus wax esters are the major energy reserve during a long starvation period. 3. 3. The phospholipid fatty acid composition showed no major changes during starvation but the wax esters lost all polyunsaturated components.

[1。 1.从太平洋不同区域采集的中胚层桡足类（Gaussia princeps）的不同阶段具有蜡酯作为主要脂质类别（脂质的49-72％）。 2. 2.在饥饿的前七天，仅使用甘油三酯（12-18％的脂质），然后缓慢消耗蜡酯储存。饥饿60天后，由于蜡酯的利用，脂质从每个个体的1.6降低到0.4mg，其中这种降低为1.0mg。因此，蜡酯是长期饥饿期间的主要能量储备。 3. 3.磷脂脂肪酸组成在饥饿期间没有显示出重大变化，但蜡酯失去了所有多不饱和成分。
