“…In addition, CDA results produced 58% total successful classification rate. A series of studies confirmed that otolith shape indices could be used for inter and intraspecific discrimination of species (Tuset et al, 2003;Morat et al, 2008;Ozpiçak et al, 2018;Yedier, 2021;Akbay et al, 2022;Pavlov, 2022).…”

“…Taxonomy and systematics are the cornerstone of all biological sciences. Many morphological traits, for example hard elements like otoliths, scales, and bones, are used by taxonomic investigations in ichthyology to identify species (Kontaş et al, 2020;Kikuchi et al, 2021;Akbay et al, 2022;Mejri et al, 2022;Jawad et al, 2022). These hard structures are one of the most useful anatomical features for various research of fish, leading to many practical applications (Schulz-Mirbach et al, 2019;D'Iglio et al, 2022).…”

In this study, the morphology of the sagittal otolith of Salmo coruhensis Turan, Kottelat & Engin, 2010 and Salmo fahrettini Turan, Kalayci, Bektaş, Kaya & Bayçelebi, 2020 from Çam Stream (Artvin) and Terme Stream (Samsun) was described by images of scanning electron microscopy. Its shape and contour were also analyzed with shape indices, elliptic Fourier coefficients and wavelet transforms. As the study material, a total of 30 S. coruhensis sample and 20 S. fahrettini sample were obtained. Interspecies differences in otolith shape and morphometry were evaluated by principal components analysis, canonical discrimination analysis, and permutational multivariate analysis of variance. The two salmonid species studied were distinguished by both morphometric and shape analysis methods. However, wavelet transform was found to be more effective than shape indices and elliptic Fourier coefficients in species discrimination, with an overall classification success rate of 80%. Our results showed that saccular otolith morphology could be an additional diagnostic character for trout species differentiation.

“…Anatomical parts of fish species are of fundamental importance in fisheries research. They can be used by many researchers in various subjects such as determination of species‐specific structures and their characteristics, species identification and discrimination, and control of the health and developmental status of fish individuals (Akbay et al, 2022; Bolgan & Parmentier, 2020; Özpiçak et al, 2021; Saygın et al, 2017; Yedier et al, 2019; Yedier & Bostanci, 2021; Yedier & Bostanci, 2022). Fishes are one of the most diverse groups of vertebrates in aquatic systems.…”

The fish's inner ear consists of three interconnected semicircular canals and otolith organs located in these canals, which are responsible for balance and hearing. Abnormalities in these organs can affect the vital activities of the fish. The main purpose of this study was to determine the morphological and morphometric characteristics of abnormal and normal sagittal otoliths in the four flatfish species (Lepidorhombus boscii, Platichthys flesus, Solea solea, and Pegusa lascaris) sampled from three seas (Aegean Sea, Mediterranean Sea, and Black Sea). Abnormalities in otoliths are investigated using light microscopy, scanning electron microscopy, and Raman spectroscopy. The otolith morphometric measurements and morphology are recorded for abnormal and normal otoliths for each species. It was determined that the four flatfish species examined in the present study showed differences in the morphological features of normal and abnormal otoliths in the blind and eyed sides. In addition, statistical differences were observed when the weight, length, width, perimeter, and area values of normal and abnormal otoliths of all species were compared (p < .05). The four types of saccular otoliths were defined, one normal (type 0) and three abnormal (type 1, type 2, and type 4) for four flatfish species. The current study presents for the first-time abnormal otolith morphology information on blind and eyed side sagittal otoliths in these flatfish species. Abnormalities in the anatomical structures of bony parts such as otoliths in fish may be caused by pollution, nutritional problems, stress, and environmental factors as well as a combination of these.
