“…In the past, otolith morphology has been useful for taxonomic identification in many fish species (Bergenius et al, 2006;Jawad et al, 2017). Recently, there are a lot of study about otolith shape, relationships between length and otolith morphometric in the literature (Leguá et al, 2013;Felix et al, 2013;Dörtbudak & Özcan, 2015;Bostancı et al, 2015;Bose et al, 2017;Jawad et al, 2017;Zhao et al, 2017;Duncan et al, 2018;Saygın et al, 2017;Zengin Özpiçak et al, 2018).…”

“…The otolith shape varies from round in fish larvae to a specific shape in adults (Lagardère et al 1995). Therefore, in many studies, including this one, data are standardized to eliminate the length and size factor (Zhao et al 2017;Tuset et al 2018;Saygın et al 2020). In the present study, two length classes were established according to the stages of gonadal development and the classification score was calculated as 79.9%.…”

Otolith phenotypic variability was analyzed in the Caucasian bleak (Alburnus escherichii) from the Selevir Reservoir in Turkey. Utricular (lapillus) and lagenar (asteriscus) otoliths were removed, while distinguishing between left and right otoliths. All otoliths were photographed on the distal (for asterisci) and dorsal surface (for lapilli) using a Leica DF295 digital camera. Otolith morphometrics were measured to the nearest 0.001 mm using Leica Imaging Software. Linear and nonlinear (power) models were applied to determine the relationships between otolith measurements and total length of fish individuals. Two length classes (Class I: 6.7–10.9 cm Lt ; Class II: 11.0–15.0 cm Lt ) were established to analyze the shape of otoliths. The Form Factor, Circularity, Roundness, Rectangularity, Aspect Ratio and Ellipticity were used to analyze the shape of otoliths. A standardized model was used to remove the effect of size on otolith measurements. Multivariate analysis was performed to detect differences in otolith shape variation. The results of discriminant function analysis showed that 79.9% of A. escherichii specimens were correctly classified by length classes. In this study, intraspecific variation of asteriscus and lapillus otoliths in A. escherichii is reported for the first time. The results of this study provide the first comprehensive data on otolith shape analysis and the relationship between otolith morphometrics and total length in the Caucasian bleak.

“…Although otoliths typically exhibit a species-specific morphological structure, they may also exhibit intraspecific changes in shape and size in relation to physiological and environmental factors [6]. Variations in otolith morphology have been observed among several populations or stocks of the same species [7][8][9][10], as well as within a species depending on factors such as sex [11,12], diet [13,14], and ontogeny [15,16].…”

An otolith shape and morphometric analysis was performed on European eel (Anguilla anguilla) subpopulations from five rivers and three coastal lagoons of Sardinia (central-western Mediterranean) to assess the role of different habitats on otolith development. Sagittal otolith shape was described by 11 harmonics from elliptic Fourier descriptors. Comparisons among the harmonics were run through canonical discriminant analyses (CDAs). The CDA reclassification rate (75.7%) demonstrated a spatial environmental discrimination among local eel subpopulations of Sardinia. The Euclidean distance values demonstrated a dissimilarity between the river and lagoon groups. The form factor and roundness shape indices were significantly higher in the river group than in the lagoon group. The distances of the first three rings to the otolith core revealed site-specific otolith development. Moreover, the annual otolith growth rate was faster in the lagoon group than in the river group. The differences among the studied sites in terms of sagittal otolith shape could relate to changes in different local stocks potentially related to environmental peculiarities. Establishing a direct correlation between otolith morphology and environmental factors is challenging, and further studies are needed to investigate the relationship between habitat type/environmental variation and growth/body characteristics of eels. Nevertheless, the achieved results suggest that this method can be considered to be a valuable tool for studying the ontogeny of the European eel.
