摘　　要：在曼氏无针乌贼(Sepiella maindroni)性腺成熟阶段(4～5月)对其进行饥饿处理,以空腹处理组饥饿0d(禁食1d)、饥饿12d(禁食13d)和饥饿24d(禁食25d)为取样时间取其肝脏和卵巢组织进行脂肪酸组成及质量分数测定。结果表明,随着饥饿时间的延长,乌贼体质量下降,肝脏和卵巢萎缩,肝脏中的饱和脂肪酸(SFA)和单不饱和脂肪酸(MUFA)较空腹处理组有显著下降(P<0.05),而多不饱和脂肪酸(PUFA)和高不饱和脂肪酸(HUFA)均有显著提高(P<0.05)。与肝脏相比,乌贼卵巢中的各脂肪酸组成在饥饿12d变化较小,饥饿24d时∑SFA较空腹处理组有极显著下降(P<0.01),而∑MUFA、∑PUFA+∑HUFA和∑n-6PU-FA显著高于空腹处理组(P<0.05)。Sepiella maindroni samples at sexual maturity （4- 5 months） were starved for 0, 12 and 24 days, then the liver and ovary were examined to study the effects of starvation on the fatty acid composition. The results showed that with the prolongation of starvation time, there were weight loss, atrophy of liver and ovary in S. maindroni. Compared with the fasting group, the percentage of saturation fatty acid （SFA） and monounsaturated fatty acid （MUFA） in the liver of stained S. maindroni decreased significantly （ P 〈 0.05 ） , while the percentages of polyunsaturated fatty acid （PUFA） and highly-unsaturated fatty acid （HUFA） increased significantly （ P 〈0. 05 ）. Compared with the case of liver, the fatty acid composition of ovary in S. maindroni remained relatively constant within the 12- day starvation, but as for the 24-day starvation, the percentages of .~, SFA declined very significantly （P 〈 0. 01 ） while those of ∑ MU- FA, ∑ PUFA ＋ ∑HUFA and ∑n-6 PUFA increased significantly in comparison with the fasting group （ P 〈 0.05 ）.
