金乌贼的生物学特性及增殖技术

金乌贼广泛分布于俄罗斯远东海海域,中国沿海,日本本州、四国、九州海域,朝鲜西海岸、南海岸海域,以及菲律宾群岛海域。它不仅是中国沿岸渔业的重要捕捞对象,也是一种具有较高经济价值的优良品种。本文综述了国内外关于金乌贼生物学和增殖技术的研究,着重介绍了金乌贼形态学、渔业生物学、行为生态学及遗传学的研究内容,探讨了金乌贼受精卵的人工孵化、幼体发育及产卵基的材质、形状、稳定性和颜色等对金乌贼附卵的影响。提出了目前在金乌贼增殖技术研究中存在的一些问题以及今后的研究方向。

Biological characteristics and multiplication techniques of Sepia esculenta

Sepia esculenta (Cephalopoda: Sepioidea) is widely distributed in the sea areas of Russian Far East, China, Japan, Korea and Philippines. It is not only one of the most important species of coastal fisheries resource in China, but also a good wild species with high commercial value. This paper reviewed the research advances on the biological characteristics and multiplication techniques of S. esculenta, with the focus on its morphology, fishery biology, behavior ecology and genetics, as well as the artificial hatching of fertilized egg, paedomorphosis, and effects of material quality, shape, stability and color of spawning substrates on attachment of fertilized egg, and discussed the existing problems and future directions in researching the multiplication techniques of S. esculenta.
