Based on the differentfeatures used, the recognition algorithms for two-dimensional object shapes could be classified into the following six categories: dominant point based approach [4, 5], polygonal approximation approach [6, 7], curve segment approach [8, 9], Fourier descriptors approach , wavelet approaches [11, 12], skeleton approach  and scale space filtering approach .
The cosine and sine curves can be defined mathematically in a series of Fourier descriptors and used as variables to compare otolith shapes among individuals or potential stocks (Christopher and Waters, 1974; Younker and Ehrlich, 1977).
