摘要
耳石的轮纹结构与化学组成相当稳定,记录了个体生活过程中丰富的生物-物理-化学环境信息,是一种很好的信息载体。因此,通过耳石信息分析可以揭示头足类的生活史历程,掌握其生活史各阶段的生态环境特征,这不仅具有重要的理论意义,而且具有较为广阔的应用前景。文章依据近年来国内外有关头足类耳石信息分析的研究成果,综述了头足类耳石日轮及微量化学的研究现状,概括了耳石信息分析在渔业资源及环境科学等方面的应用,并对今后的研究工作提出了方向与内容上的展望。
Increments structure and chemical composition of the statoliths are quite stable and record information about biological, physical and chemical environmental characteristics of different stages of life history. Information analysis can reveal the life history of cephalopods and the environmental condition and its varieties. This has important theoretical significance, and will be broadly applied. Based on the domestic and foreign researches on information analysis of statoliths in Cephalopods during recent years, the paper summarized the current status of daily growth increment and microchemistry of statoliths in Cephalopods ; and generalized its application in fishery resource and environmental science. In the meanwhile, the paper made the prospects on direction and content of the future research.
