“…A strong relationship between fish length and otolith size suggests that somatic growth has a major effect on otolith growth (Munk 2012); there are published reports about similar relationships revealed between somatic and otolith growth (Aneesh-Kumar et al 2017;Yilmaz et al 2019). In the present study, linear regressions between fish length and otolith size showed a higher coefficient of determination (r 2 > 0.8) except between fish length and otolith height for L. bata.…”

The present study was conducted to investigate the relationships between fish length, otolith size and otolith weight. A total of 180 Sperata aor and 171 Labeo bata specimens were collected monthly during January 2016 to March 2017 from the River Ganga at the Narora site. Student’s t-test showed no significant differences in the size of right and left otoliths in the selected fish species, therefore, a single linear regression based on the left otolith was carried out. Fish length was plotted against otolith weight, otolith length and otolith height. Moreover, otolith length was plotted against otolith weight and otolith height. The linear regression model was found to fit the data well for fish length to otolith size in both selected fish species. A strong relationship between otolith length and weight was found in both species (r2 > 0.8). Furthermore, the study revealed that fish length is potentially related to otolith size and a strong relationship between fish length and otolith size exists in S. aor (mean r2 = 0.89) as compared to L. bata (mean r2 = 0.70). Such relationships should be determined for the fish species that are ecologically and socio-economically important in order to understand their trophic relationships, population dynamics and yield estimates.

“…The studies on otolith biometry have focused on the relationship between fish length and otolith length (Granadeiro and Silva 2000;Viva et al 2015;Yılmaz et al 2019). Also, the relationships between fish length and different measurements (width, height) of otolith were frequently defined in recently (Yilmaz et al 2015;Aneesh Kumar et al 2017;Kanjuh et al 2018;Kurucu and Bostanci 2018).…”

“…The relationships between otolith dimensions and fish length can be supply significant knowledge to determine fish length from otoliths in the stomach of predators and understand prey-predator relationships (Aguilar-Perera and Quijano-Puerto 2016). Although there have been a lot of studies on these relationships in many fish species (Viva et al 2015;Bostancı et al 2017;Yılmaz et al 2019), there are no known studies for Wels catfish.…”

The relationships between dimensions of the asteriscus and lapillus and fish length for Wels catfish, collected from Sıddıklı Dam Lake between September 2015 and August 2016, are presented. No significant differences were noted between the dimensions of the left and right otoliths, and between otolith dimensions of male and female. For analyses, the right-side data of otoliths were used regardless of sex. The strongest correlation coefficient was obtained from the linear model for all relationships. Thus, a linear model was used for determining relationships. The r 2 values of relationships between asteriscus dimensions and total length were more appropriate than relationships between lapillus dimensions and total length. Asteriscus height was more suitable than other otolith dimensions for predicting the length of Wels catfish. Results provided the first information on relationships between total length and otolith dimensions of Wels catfish. These relationships from this study can provide a reliable tool to reconstruct the predator diet, and to estimate the size of the prey, as well as also provide support to paleontologists in their research on fish fossils.

“…Linear and nonlinear functions are preferred to describe relationships of otolith dimensions and fish size. Generally, the nonlinear function was used in otolith morphometrics and total length relationships (Waessle et al 2003;Saygin et al 2017;Jawad et al 2017;Kanjuh et al 2018;Zengin Özpiçak et al 2018;Yilmaz et al 2019;Saygin et al 2020;Bulatović et al 2021). However, in Ladik Lake, the linear regression model was found more stronger, and it was determined that the nonlinear regression is more useful in explaining the relationships between otolith measurements and total length.…”

This study was carried out to investigate the relationships between total length and otolith dimensions and to detect the otolith shape index values of Northern pike (Esox lucius) which has high economic value, sampled from Ladik and Simenlik Lakes. A total of 140 specimens (Lake Ladik: 82 individuals, Lake Simenlik: 58 individuals) were sampled. Otolith height, length, perimeter, and area were determined by Imaging Software. Nonlinear and linear models were applied to estimate the relationships between the otolith measurements and total length. Form factor, circularity, roundness, rectangularity, aspect ratio, and ellipticity were used for otolith shape analyses. It was found that the relationship between the total length-otolith length was found to have the highest r2 value (Lake Ladik r2=0.949, Lake Simenlik r2=0.914) among the total length-otolith morphometrics at both localities. Otolith shape indices were calculated by using otolith measurements. As a result of comparing shape indices, it was found that there was a significant difference in two localities using roundness, ellipticity, and aspect ratio (P <0.05). The results indicated otolith shape indices could be used as a suitable tool to discriminate Northern pike populations.
