Abstract:With the experience of using Simrad EY60 echosounder in the inland water fish resource investigation from 2005,we introduced the operation and results of EY60.Basing on Split-beam technology,EY60 system also developed cross-filter and tracking analysis method,make it true of auto single target detect and count,which would be widely used in the research of fish ecology.In this article the diminution of noise and the importance of reference with fishery data were discussed.In addition,the necessity and urgent...
