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,因而在渔业资源评估中应用广泛。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技术在渔业资源生物量评估中的研究现状,从eDNA技术与传统方法互补性、eDNA浓度影响因素及模型、生物量定量模型等方面展开阐述,并对以后的研究方向提出新思路,为eDNA技术在渔业资源生物量评估中应用提供参考。The global fishery resources are now under endangerment due to the continual interruption triggered by human activities in the past few years.To evaluate its deleterious effects,the environmental DNA(eDNA)assessment method has been established to be more advantageous for its simple operation,low invasiveness,and high sensitivity,and hence widely used in comparison to the traditional assessment techniques.It has also been proven to be more constructive to analyze the biomass and the species abundance.This study summarizes the investigation carried out by the eDNA technique to evaluate the biomass of fishery resources,including the following aspects:the comple-mentarity of the eDNA and the traditional methods,factors and models of the eDNA concentration,and the quanti-tative models of the biomass.What’s more,this review provides new perspectives for future study,which will im-part the crucial standpoint of the eDNA technology application in relation to the biomass assessment of fishery re-sources.
