| Abstract: | 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. |
