“…Thus, we can assume that this asymmetry is most likely due to the vulnerability of the individual who may develop asymmetry in both sides of the otolith under stress conditions (Jawad et al, 2011). In this regard, Jawad et al (2011) and Mejri et al (2020) concluded that there is a direct relationship between environmental stress and asymmetry in the morphology of fish species. Indeed, the environmental stress can arise from the pollution of seawater and sediments with heavy metals, organic matter and hydrocarbons (Zrafi-Nouira et al, 2008;Khenfech & Boumaiza, 2011;El Zrelli et al, 2018;Boulajfene et al, 2019).…”

“…During the last decades, study of the morphological characteristics of otoliths, in particular their shape, length, width, area, thickness and weight, has been used to test both genetic and environmental stressors and as a bioindicator to test the differentiation of populations and the variance in stock discrimination studies using Elliptical Fourier analysis (EFA) (Valentine et al, 1973;Campana & Casselman, 1993;Begg & Waldman, 1999;Torres et al, 2000;Smith et al, 2002;Panfili et al, 2005;Turan, 2006;Jawad et al, 2010Jawad et al, , 2011Jawad et al, , 2012aJawad et al, , 2012bJawad et al, , 2012cJawad et al, , 2016Jawad et al, , 2020Vignon & Morat, 2010;Cañás et al, 2012;Jawad, 2012Jawad, , 2013Lord et al, 2012;Treinen-Crespo et al, 2012;Mahe et al, 2014;Trojette et al, 2014Trojette et al, , 2015Abu El-Regal et al, 2016;Brophy et al, 2016;Hüssy et al, 2016;Rebaya et al, 2016Rebaya et al, , 2017Al-Busaidi et al, 2017;Fatnassi et al, 2017;Ider et al, 2017;Khedher et al, 2017;Rodgveller et al, 2017;Chakour & Elouizgani, 2018;Khemiri et al, 2018;Kontaş et al, 2018;Mejri et al, 2018;Wang et al, 2018;…”

For the first time, saccular otolith shape and size were analysed in 254 samples of the bogue Boops boops collected from the marine stations of Bizerte and Kelibia situated in north-east Tunisia. The objectives were (1) to examine the inter- and intra-population variation in the otolith shape and size, including length (Lo), width (Wo) and area (Ao) measurements, and (2) to assess the relationship between otolith mass asymmetry (OMA) and total fish length (TL). In addition, the impact of pollution present in these two stations on the shape and size of the otolith in relation to the TL was discussed. Analyses of the otolith shape and biometric data showed a statistically significant asymmetry in the otolith shape (P < 0.0001) between the right and left sides within the population of Bizerte, as well as between the otoliths from the same right-right and left-left sides between the populations of Bizerte and Kelibia. Similarly, a significant Wo asymmetry (P < 0.05) was recorded within the population of Kelibia. Conversely, a significant symmetry was detected in Lo and Ao (P > 0.05) between the right and left sides within the populations of Bizerte and Kelibia. Moreover, the level of asymmetry of Ao was higher than that of Lo and Wo in both populations. Nevertheless, Student's t-test showed no statistically significant differences (P > 0.05) for Lo, Wo and Ao in relation to the means of TL between the three groups of the populations of Bizerte and Kelibia, although significant differences (P < 0.05) were found by using box plots. Furthermore, no statistically significant relationship (P > 0.05) was detected between OMA and TL within and between the populations of Bizerte and Kelibia. The possible cause of fluctuating asymmetry (FA) in the otolith shape and size both within and/or between populations of the two stations has been discussed in relation to the instability of development induced by environmental stress associated with the variation in water temperature, salinity, depth, feeding conditions and pollutants present in these stations.

“…Otolit kütle asimetrisi hem insanlardaki hem de balıklardaki vestibüler boşluk bozukluklarının oluşumunda önemli rol oynayabilmektedir (Lychakov & Rebane, 2004). Balıkların otolitlerinde kütle asimetrisi meydana geldiğinde, genellikle davranışlarında önemli değişiklikler gözlemlenir (Lychakov & Rebane, 2004;Jawad, 2013). Asimetri, balığın vestibüler ve işitsel fonksiyonları üzerinde güçlü etkilere sebep olmaktadır (Lychakov vd., 2006).…”

“…Ayrıca otolit morfolojisi üzerine Portekiz kıyılarında (Assis, 2003) ve Atlantik Denizi'nde (Tuset vd., 2008) yapılan çeşitli çalışmalar da bulunmaktadır. Ancak, dünyada ve ülkemizde yapılmış otolit asimetrisi çalışmaları oldukça az sayıda olup bunların birçoğunu da deniz balıkları oluşturmaktadır (Lychakov vd., 2006;Jawad vd., 2010;Jawad vd., 2011;Jawad, 2013;Jawad & Sadighzadeh, 2013;Bostancı vd., 2018;Kontaş vd., 2018;Kontaş vd., 2019;Yedier vd., 2018aYedier vd., , 2018b. Bununla birlikte, sınırlı sayıda da olsa tatlı su balık türleriyle de yapılan çalışmalar da bulunmaktadır (Lychakov vd., 2006;Kontaş vd., 2017;Yedier vd., 2017).…”

Asimetri, balığın vestibular ve işitsel fonksiyonları üzerinde önemli etkilere sebep olmaktadır fakat bu konuyla ilgili olarak sınırlı sayıda çalışma bulunmaktadır. Bu çalışmanın amacı, Ordu ili içme su kaynağı olarak da kullanılan Melet Irmağı’nda yayılış gösteren C. banarescui türünde, daha önceden belirlenmemiş olan, otolit kütle asimetrisi (x) ve mutlak otolit kütle asimetrisinin (|x|) belirlenmesidir. Balıkların total boyları ölçülmüş, asteriskus otolit çiftleri çıkarılarak 0,0001 hassasiyetle tartılmıştır. Otolit kütle simetrisi (x), mutlak otolit kütle asimetrisi (|x|) ve otolit kütle farkı (MR-ML) değerleri hesaplanarak, balık boyu ile x, |x| ve (MR-ML) arasındaki ilişkiler belirlenmiştir. C. banarescui bireylerinin sağ ve sol otolit ağırlıkları arasındaki fark, paired-t testine göre istatistiksel olarak önemsiz bulunmuştur (P>0,05). Ortalama x ve |x| değerleri -0,00803 ve 0,0855 olarak hesaplanmıştır. Total boy-x, total boy-|x| ve total boy-(MR-ML) arasındaki ilişkiler sırasıyla y=0,0011x+0,0434; y=0,0066x+0,1457 ve y=0,0000008x+0,00003 olarak tespit edilmiştir.

“…Numerous studies on the weight difference of the otolith of fishes from the Omani waters were published in the recent years (i.e., Jawad et al, 2010;Jawad et al, 2011;Ambuali et al, 2011;Jawad et al, 2012;Jawad, 2013), but there is no such study on L. ehrenbergii. Therefore, the present work is a significant addition to the knowledge of otolith mass asymmetry in the area of Sea of Oman.…”

Otolith weight difference on both sides of the fish head, x, was estimated. Sagittae otolith mass asymmetry was investigated in the littoral lutjanid species Lutjanus ehrenbergii. The absolute value of |x| in Lutjanus ehrenbergii does correlate with the fish length and otolith development. Such case is similar to that in the symmetrical fish species, the absolute. An increase in the absolute value of otolith asymmetry in relation to the fish size was observed. The range of x magnitude was between -0.2 and +0.2.
