| 摘 要： | 近年来,由于过度频繁的人类活动,导致全球渔业资源正遭受威胁。与传统渔业评估方法相比,环境DNA(eDNA)技术具有操作简便、侵入性低、灵敏度高等优点,因而在水生生态系统中应用广泛。eDNA技术在物种丰度和生物量评估中已经被证明是可行的,本文总结了eDNA技术渔业资源生物量评估中的研究进展,从eDNA技术与传统方法互补性、eDNA浓度影响因素及模型、生物量定量模型以及应用前景等方面展开阐述,为以后eDNA技术在渔业资源生物量评估中应用提供参考。

| Abstract: | In recent years, owing to continuous human activities, the global aquatic ecosystem is now under threat. Compared with traditional fishery assessment methods, environmental DNA (eDNA) has the advantages of simple operation, low invasiveness, and high sensitivity. So it is widely used in aquatic ecosystems. It has been proved to be feasible in species abundance and biomass assessment. This study summarizes the researches of eDNA in biomass assessment in the aquatic ecosystems including the following aspects: the complementarity of eDNA and traditional methods, factors and models of eDNA concentration, quantitative models of biomass and application prospects. This review will provide reference for the application of eDNA technology for biomass assessment in the aquatic ecosystem. |
