水生甲壳动物硬组织生长带计数鉴龄法研究进展

    Research progress in method of hard tissue growth band counting for age determination in aquatic crustaceans

    • 摘要:
      背景 甲壳动物是渔业和水产养殖业中一类具有重要商业价值的生物资源。近些年来,由于某些传统渔业的衰退和人类对高蛋白食物需求的增长,甲壳动物如蟹、龙虾、虾、磷虾等资源被大量开发。因此,亟需发展甲壳动物的资源评估和管理工作,以维持其资源的可持续发展,但甲壳动物年龄鉴定的困难阻碍了这项工作的开展。目前,鉴定甲壳动物年龄的方法有许多种,主要包括饲养法、标记重捕法、体长频次法、脂褐素分析法、放射性同位素法以及硬组织生长带计数法等,其中硬组织生长带计数法被广泛应用,备受关注。
      进展 基于以上背景,本文首先介绍了甲壳动物的生物学特性和硬组织结构,阐述利用硬组织生长带计数法鉴定水生甲壳动物年龄的主要实验过程,与以往水生甲壳动物年龄鉴定方法进行对比,分析该方法的优点和缺点,并对利用硬组织生长带分析水生甲壳动物年龄与生长的研究进展进行回顾,对该方法未来需要进一步解决的问题和发展方向作出展望。
      展望 在未来水生甲壳动物年龄鉴定的工作中,需进一步了解生长带沉积机制,准确掌握硬组织生长带的计数,深入分析所获得的实验数据,并开展相关的验证实验等。
      意义 本文可为水生甲壳动物的年龄鉴定工作提供一个系统的参考。

       

      Abstract:
      Background Crustaceans are a type of biological resource with significant commercial value in fisheries and aquaculture. In recent years, due to the decline of certain traditional fisheries and the increasing demand for high protein foods, resources of crustaceans such as crabs, lobsters, shrimp, and krill have been extensively developed. Therefore, it is necessary to develop stock assessment and management of crustaceans to maintain their sustainable development. However, for crustaceans, the challenge of determining age hampers the development of accurate stock assessments. At present, there are many methods for identifying the age of crustaceans, mainly including feeding method, marker recapture method, body length frequency method, lipofuscin analytical method, radioisotope method, and hard tissue growth band counting method. In recent years, the hard tissue growth band counting method has gained widespread use and significant attention.
      Process  Based on the above background, this article first introduces the biological characteristics and hard tissue structure of crustaceans, describes on the experimental process of using the hard tissue growth band counting method to identify the age of aquatic crustaceans, compares it with other methods for identifying the age of aquatic crustaceans, analyzes the advantages and disadvantages of this method, and reviews the research progress of using hard tissue growth zones to analyze the age and growth of aquatic crustaceans. Perspectives are provided on the future challenges that need to be addressed and the development direction of this method.
      Prospect  It is pointed out that in the future work on age determination of aquatic crustaceans, it is necessary to further understand the sedimentation mechanism of growth zones, accurately grasp the counting of hard tissue growth zones, conduct in-depth analysis of the experimental data obtained, and conduct relevant verification experiments.
      Significance  This paper may provide a systematic reference for future age determination of aquatic crustaceans.
