Otolith Shape and Characteristics as a Morphological Approach to the Stock Identification in Barbus tauricus (Cyprinidae)

Stock Discrimination of Northern Pike Esox lucius L., 1758 Inhabiting Lakes Simenlik and Ladik (Samsun-Turkey) Using Otolith Biometry and Shape Analysis

“…Otoliths are considered as an invaluable source of information for reconstructing a fish's life cycle (Campana and Thorrold 2001). In addition, otolith morphology and shape analysis are often used for stock discrimination (Begg and Brown 2000;Galley et al 2006;Leguá et al 2013;Bostancı and Yedier 2018;Ozpicak 2020;Bano and Serujiddin 2021;Yedier 2021). However, the relationships between length and otolith dimensions generate a baseline for fish biology and fisheries research (Ozpicak 2020).…”

“…In addition, otolith morphology and shape analysis are often used for stock discrimination (Begg and Brown 2000;Galley et al 2006;Leguá et al 2013;Bostancı and Yedier 2018;Ozpicak 2020;Bano and Serujiddin 2021;Yedier 2021). However, the relationships between length and otolith dimensions generate a baseline for fish biology and fisheries research (Ozpicak 2020). Because being otolith shape is species-specific, they are widely used in several different studies, such as species differentiation with otolith shape (Cardinale et al 2004), identifying fossil samples (Gierl and Reichenbacher 2015) or dietary items in a stomach content (Škeljo and Ferri 2012).…”

“…This is the first study about the otolith shape of E. lucius from different lakes. Otolith properties are useful tools to identify intra and interspecific relationships (Leguá et al 2013;Mapp et al 2017;Saygin et al 2020;Ozpicak 2020;Bano and Serujiddin 2021) and stock discrimination (Begg and Brown 2000;Galley et al 2006;Agüera and Brophy 2011;Vieira et al 2014;Jemaa et al 2015;Bacha et al 2016;Afanasyev et al 2017;Duncan et al 2018;Zengin Özpiçak et al 2018). In the literature, no other study on this subject related to E. lucius could be found.…”

“…Fish size-otolith biometry relationships have several benefits in estimating the size of the prey. Fish size and/or weight can be functionally related to an appropriate otolith measurement (length, width, or weight) and the resulting relationships can subsequently be used for size estimation (Battaglia et al 2010;Yilmaz et al 2015;Mehanna et al 2016;Bostanci et al 2017;Saygin et al 2017;Yazicioğlu et al 2017;Ozpicak 2020;Fey and Greszkiewicz 2021;Osman et al 2021).…”

Otolith phenotypic analysis for the endemic Anatolian fish species, Caucasian bleak Alburnus escherichii Steindachner, 1897 (Teleostei, Leuciscidae), from Selevir Reservoir, Akarçay Basin, Turkey

“…In ostariophysians, lagenar and utricular otoliths are larger than saccular otoliths (Wright et al 2002). Otolith phenotypic variation has long been used for different types of ichthyological studies, especially taxonomy (Więcaszek et al 2020), genetics and phylogeny (Firidin et al 2017), predator-prey relationships (Więcaszek et al 2020), fossil studies (Gierl & Reichenbacher 2015), mass asymmetry (Yedier et al 2018), paleoichthyology (Gierl et al 2018), bioarchaeology (Van Neer et al 2004), trophic ecology (Assis et al 2020), age determination (Sun et al 2020) and stock identification (La Mesa et al 2020;Ozpicak 2020).…”
