Comparative Analysis of the Otolith Features of Tarek (Alburnus tarichi (Güldenstädt, 1814)) Inhabiting Van Basin (Lake Van, Erçek, Nazik, Aygır) Between Localities

Abstract

In the present study, a comparison of the otolith morphology of Alburnus tarichi, collected from different localities throughout Van Basin was carried on. A total of 351 specimens of A.tarichi collected by trammel nets from four different localities (Van, Erçek, Nazik, Aygır) during the period April-May 2015 were examined. Fork length and body weight of the specimens ranged between 9.9-24.6 cm and 8.4-176.5 g, respectively. Lagenar otoliths were removed discriminating as left and right. Otolith length (OL), otolith breadth (OB) and otolith weight (OW) were collected. Comparisons of right-left otolith measurements were tested by paired t test. Comparisons of otolith breadth, length and weight of A. tarichi among all localities were tested by ANOVA. There were no significant difference in terms of otolith length and weight between right and left otoliths but there were statistically significant difference in terms of otolith breadth between the specimens collected in Lake Van and Lake Erçek. There were no differences between right and left otolith measurements in Lake Nazik and Lake Aygır. Comparing all localities together, otolith length, breadth and weight were different from each other for four localities. The power model was applied to estimate the relationships between the otolith measurements and fish length.

The Relationships Between Otolith Dimensions-Total Length and Otolith Features of European Perch (Perca fluviatilis L.,1758) Sampled from Yedikır Dam Lake (Turkey)

“…In this study, when right and left otolith were compared, there were no significant differences in terms of otolith length, otolith breadth and weight, too (P˃0.05). There are also different studies which show no difference between right and left otoliths (Jawad et al, 2011;Zengin et al, 2015;Saygın et al, 2017;Zengin et al, 2017).…”

“…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).…”

“…Otolith morphology varies between species, however separate stocks of the same species, often identical physically can sometimes be discriminated through subtle differences in otolith morphometrics (Tuset et al, 2003;Zengin et al, 2015;Ibáñez et al, 2017;Mapp et al, 2017). When the relationship between otolith dimensions and total length in a species is determined, the total length or standard length of a fish from its otolith dimensions can be estimated, or vice versa (Şen et al, 2001;Battaglia et al, 2010;Başusta et al, 2013;Yilmaz et al, 2014;Saygın et al, 2017;Yazicioğlu et al, 2017;Zengin et al, 2017;Ozpicak et al, 2018;Souza et al, 2019).…”

“…Stock identification is a basic requirement to describe the stock status and to support better stock assessment of fishery (Cadrin et al, 2005).Otolith shape analysis is a basic method for seperating fish stocks. Also there are a lot of studies about intraspecific variations of fish stocks from otolith shape (Vignon and Morat, 2010;Bostancı et al 2015;Zengin et al, 2015;Hüssy et al, 2016;Avigliano et al, 2017;Saygin et al, 2017;Bostancı and Yedier, 2018;Song et al, 2018;Yedier et al, 2019). Otoliths are innate data archives that document information in their microstructure and chemistry at different spatial and temporal scales related to their growth and environment (Miyan et al, 2016).…”

“…The relationship between the fish size and otolith dimensions is of great importance (Battaglia et al, 2010;Zan et al, 2015;Saygin et al, 2017;Zengin et al, 2017).…”
