The Three-frequency Method for Classifying the Species and assessing the Size of two Euphausiids (Euphausia superba and Euphausia crystallorophias)

摘要

In this paper an acoustic method for identifying two euphausiid species and estimating their length is described. The approach is in fact an outgrowth from both the fluid sphere and Bayes rule methodologies. Some practical results of the method are presented.
