摘要
总结了利用SimradEK50 0声学系统进行了南海区多鱼种资源评估经验 ,介绍了多鱼种声学评估的工作流程 ,包括调查方案制定、声学数据采集、映像分析、积分值分配、资源量的计算方法等关键过程 ,同时及在工作中应该注意的细节。
This paper summarizes the know how developed in first time work that multi species acoustic assessment with Simrad EK500 system conducted from 1997 to 2001 in the South China Sea. And by using acoustic method to do stock assessment, the paper discusses work programme of multi species acoustic assessment, including such key steps as preparing survey plan, collection of acoustic observations, interpretation of echograms, allocation of backscattering strength values and calculation of biomass, etc, and points out a number of technical details which is supposed to come into notice in course of assessment.
