Summary Sagittal otoliths from the Atlantic and Mediterranean regions of Serranus cabrilla L. were compared using shape indices (form-factor, roundness, circularity, rectangularity, ellipticity and eccentricity). Regional differences were best described by form-factor, circularity and eccentricity variables. The canonical discriminant functions were built with form-factor or rectangularity indices. The results indicated slight regional variations. The G-test was the criterion more useful to identify the otolith origin in the discriminant analysis.

Characterization of local populations of the common sole Solea solea (Pisces, Soleidae) in the NW Mediterranean through otolith morphometrics and shape analysis (2007, methodology): “These measures allowed the calculation of five shape indices (Table 2) which are independent from differences in otolith size (but see hereafter) (Russ 1990; Tuset et al. 2003a, b).”
Otolith atlas for the western Mediterranean, north and central eastern Atlantic (2008, background): “…Berdar and Li Greci, 1986); species, population or fishery stock identification (e.g. Yefanov and Khorevin, 1979; Messieh, et al., 1989; Lombarte and Castellón, 1991; Castonguay et al., 1991; Campana and Casselman, 1993; Friedland and Reddin, 1994; Torres et al., 2000; Tuset et al. 2003a, 2006.)”
A comparison of otolith microchemistry and otolith shape analysis for the study of spatial variation in a deep-sea teleost, Coryphaenoides rupestris (2010, methodology): “These measurements were then used to manually calculate simple shape indices as detailed in Table 2 (Tuset et al. 2003).”
Use of otolith shape for stock identification of John's snapper, Lutjanus johnii (Pisces: Lutjanidae), from the Persian Gulf and the Oman Sea (2014, methodology): “To test for differences in the relationship between otolith weight and fish length between areas an analysis of covariance (ANCOVA) was performed, previous linear-logarithmic transformation of variables, where area was the main factor and fish length was the covariate (Tuset et al., 2003).”
