Abstract

The paper presents an application and a comparison of two mathematical approaches analyzing the shape of the otolith of some mediterranean populations of European eel: the wavelet transform and elliptic fourier. the shape variability and its relation between the otolith growth was investigated. partial least squared found an allometric and continuous growth in the relationship of otolith size and shape by comparing with a regression model between the predicted otolith sizes obtained from the efa and wl approaches, and the observed ones. Elliptic fourier method applied to european eels otolith shape analysis has obtained better performances then the wavelet transform analysis using the partial least square regression.
