头足类种群鉴定方法研究进展

头足类不仅是重要的经济软体动物,同时在海洋生态系中扮演着重要的角色。其开发和利用已引起世界各国和地区的重视。从形态学、生态学、生物化学以及分子遗传学等方面,较为系统地阐述了世界各国在头足类种群鉴定方面的研究现状。分析认为,头足类种群结构的研究在世界范围内已经取得了很大的进展,传统的形态学和生态学方法为其鉴定提供了基本的手段,其中利用耳石对其生长和产卵季节等进行推算是当前研究的主要手段之一。生物化学技术和分子遗传学标记的应用,为其研究提供了新的思路。分析认为,头足类种群鉴定还应结合其基础生物学,特别是分类学、生活史和洄游分布等方面的内容。

Current status and prospects of identification methods on the Cephalopod population

Cephalopod belongs to an important economic mollusk and also plays an important role in the marine ecological system.Its exploitation and utilization have been recognized in the world.In this paper,the current study about the population identification method for cephalopod has been discussed from the aspects of morphology,ecology,biochemistry and molecular genetics in details,the results show that the great progress has been made in the world.The traditional methods such as morphology and ecology have provided basic tools for identifying the cephalopod structure,in which the way based on statolith aging has become important.However,the application of biochemistry and molecular genetics has provided for the new ways.The results also indicate that the population identification for cephalopod may be combined with its basic biology,especially in taxology,history and migration.
