摘要
Calanus species, particularly those in high latitudes, can accumulate large oil reserves consisting predominantly of wax esters. These wax esters consist predominantly of 16:0, 20:1 (n - 9) and 22: 1 (n - 11) fatty alcohols, mainly formed de novo by the animals from non-lipid dietary precursors, esterified with various fatty acids that are often polyunsaturated fatty acids and largely of dietary, phytoplanktonic origin. Wax ester formation is maximal in copepodite stages IV and V. The lipids are elaborated not primarily for buoyancy regulation but as a source of metabolic energy during overwintering, particularly for reproduction. Large quantities of wax esters are utilised for gonadal development when stage V copepodites mature to females. Development of stage V copepodites to males is not accompanied by wax ester utilisation but males consume large amounts of these lipids in physical activity during reproduction. The role of wax esters in the life history of calanoids is illustrated with particular reference to a comparison of Calanus finmarchicus and Metridia longa in Balsfjord, northern Norway.

卡拉努斯物种，尤其是高纬度地区的卡拉努斯物种可以积聚主要由蜡酯组成的大量石油储量。这些蜡酯主要由16：0组成，20：1（n - 9）和22：1（n - 11）脂肪醇，主要由动物从非脂质膳食前体重新形成，用各种脂肪酸酯化，这些脂肪酸通常是多不饱和脂肪酸，主要来自饮食，浮游植物。在桡足类阶段IV和V中蜡的形成最大。脂质不仅主要用于浮力调节，而且在越冬期间作为代谢能量的来源，特别是用于繁殖。当V期桡足类成熟为雌性时，大量的蜡酯用于性腺发育。V阶段桡足类向雄性的发育不伴有蜡酯利用，但雄性在繁殖期间消耗大量这些脂质的体力活动。特别参考了挪威北部巴尔斯峡湾的Calanus finmarchicus和Metridia longa的比较，说明了蜡酯在calanoids生活史中的作用。
