Morphological and Biometrical Characteristics on Otolith of Barbus tauricus Kessler, 1877 on Light and Scanning Electron Microscope

Abstract

SUMMARY:The otolith morphology, biometry and the relationship between the otolith size and fish length were examined. The weight, length, width, area and perimeter were recorded for each pair of otoliths. The values of form factor (FF), roundness (RD), aspect ratio (AR), circularity (C), rectangularity (R) and elipticity (E) were calculated and the relationships between otolith length (OL) and shape indices were showed with graphics. According to paired t-test results, difference between right and left otoliths was important statistically (P<0.05), except otolith length. It is the first time, the difference of otolith variables were observed not only right and left pairs but also females and males of fish a member of Cyprinidae. While the otolith weight had the lowest coefficient of determination (r 2 ) such as 0.69; 0.59; 0.65, otolith length had the highest 0.80; 0.81; 0.80, for female, male and all specimens, respectively. In addition, SEM images were firstly shown for otoliths of B. tauricus to determine the otolith morphology.

“…These findings are in agreement with the observations of many authors who reported that, the sex difference had statistically non-significant effect on the otolith length [15,25,42]. There was no difference between females and males for mean length and weight values (t test, P>0.05) [41].…”

“…These findings were supported by other studies that considered the otolith pair were mirror images of each other [15,[22][23][24][38][39][40]. The difference between the length of the right and left otolith was statistically insignificant (P>0.05) [41].…”

Otolith biometrics and their relationships with fish sizes of Butis koilomatodon living in Mekong Delta, Vietnam

“…Rastrelliger kanagurta, collected from the Oman Sea, exhibited the strong relationship between total length of fish and otolith dimension (Jawad et al, 2011). Kontaş and Bostancı (2015) stated that the changes in the relationship between the otolith and fish size could correspond to the growth somatically between genders. In some fish species, the male could be larger than the female because it is responsible for constructing and defending the nest like Gobiusculus lavescens (Houde, 2001).…”

Ayrıca otolit morfolojisi üzerine Portekiz kıyılarında (Assis, 2003) ve Atlantik Denizi'nde (Tuset vd., 2008) yapılan çeşitli çalışmalar da bulunmaktadır.…”
