According to Cadrin & Friedland (1999), the Fourier analysis technique is an efficient method for describing all of the variation in the shape contours and the individual differences in the scale of the otolith contour (Campana & Casselman, 1993), although the biological interpretation of the results obtained from this technique is more complex than the biological interpretation of the results obtained from linear morphometry (Stransky & MacLellan, 2005).
This decomposition of periodic functions is a part of the very Fourier analysis. Each of the terms of the series in which the function is decomposed is called a harmonic, and every harmonic has a frequency that is always n times the fundamental frequency (the frequency of the first harmonic), where n is an integer.
