摘要

摘要: 探究阿根廷滑柔鱼 (Illex argentinus) 性腺发育过程中组织脂肪积累及对生殖能量的贡献，对于掌握其生殖投入策略及其资源持续开发利用具有重要理论价值。采用组织能量密度测定技术和脂肪萃取技术，测定分析阿根廷滑柔鱼雌性个体的胴体肌肉、消化腺、卵巢和输卵管卵子等组织脱脂前后的能量密度，以及各组织的脂肪质量分数、脂肪能量及其占比。结果显示：各组织能量密度在脱脂后均显著下降。在性腺发育过程中肌肉组织和输卵管卵子的脂肪质量分数及其能量占比稳定，消化腺的脂肪质量分数及其能量占比随着性腺发育显著下降，卵巢的脂肪质量分数及其能量占比随着性腺发育显著增加，在IV期达到最大值；性腺组织与消化腺的脂肪质量分数、脂肪能量及其占比等均呈显著负相关关系，而与肌肉组织无显著相关性。研究表明，阿根廷滑柔鱼的脂肪质量分数及脂肪能量积累存在组织特殊性，脂肪积累对生殖能量有重要贡献，性腺与消化腺组织间的脂肪积累密切相关，佐证了生殖能量来源主要依赖于收入型的投入策略。

Abstract: To explore the accumulation of tissue lipid and its contribution to reproductive energy during gonadal development of Illex argentinus has important theoretical value for understanding its reproductive investment strategy, as well as the sustainable development and utilization of this resource. By using tissue energy density measurement technology and lipid extraction technology, we measured and analyzed the energy density of mantle soma, digestive gland, ovary and oviduct eggs of female I. argentinus before and after degreasing, as well as the lipid mass fraction, lipid energy and proportion of each tissue. Results indicate that the energy density of all tissues decreased significantly after lipid extraction. During the maturation, female I. argentinus maintained a relative stable level of the lipid mass fraction and percentage of lipid energy in mantle soma and oviduct eggs. However, there was a significant decreasing trend in the lipid mass fraction and percentage of lipid energy in the digestive gland but an increasing trend in the ovary (Maximum in Phase IV) along with maturation. Furthermore, Pearson's r analysis indicates that there was a significantly negative relationship in the lipid mass fraction, lipid energy and percentage of lipid energy between gonadal tissues (Combination of ovary and oviduct eggs) and digestive gland, but without a significant relationship between gonadal tissues and mantle soma. In summary, female I. argentinus exhibits tissue-specific lipid content and lipid energy accumulation. The lipid content has a significant contribution to the reproductive energy, and lipids in the gonadal tissues are significantly correlated with lipids in the digestive gland, which further proves that energy allocation to reproduction in I. argentinus mainly depends on the income resources.
