“…Relationships between fish size and otolith size have been done in several fish species globally [e.g. Battaglia et al 2010, Jawad et al 2011, 2011a, 2011b, Jawad and Al-Mamry 2012, Jawad et al 2017, Oliveira et al 2019. In Iraqi marine waters, however, this information has not been well investigated [Qasim et al 2019].…”

Fish specimens (n=75) of A. arabicus were collected from the marine waters of Iraq at Khor al-Zubair. Collection was conducted in the period February–September 2019 at depth of 10–25 m. Relationships between fish length and otolith length, width and weight were calculated for the Arabian yellowfin seabream, Acanthopagrus arabicus using linear models. This study represents the first data available on the relationship of fish size and otolith size and weight for A. arabicus in the Arabian Gulf area. The various relationships between fish length otolith length, width and weight were calculated: Y = -1E – 0.06X2 + 0.0106X + 5.2628, Y = 4E – 06X2 + 0.0077X + 2.1834, and Y = 9E – 07X2 + 0.0013X – 0.191 respectively.

“…For example, the otoliths size of Periophthalmodon septemradiatus (Dinh et al, 2021b) and Glosogobius sparsipapillus in the Mekong Delta did not differ between male and female fish. Another example is several marine fish species in Brazil: Ctenosciaena gracilicirrhus, Macrodon ancylodon, Menticirrhus americanus, Haemulon steindachneri, Pellona harroweri, and Polydactylus virginicus were similar in morphometry between left and right otoliths (Oliveira et al, 2019). In the current study, the otolith weight at Tran De, Soc Trang was statistically lower than that of the other three sampling sites, possibly due to variations in food sources and habitat conditions.…”

This article first provided information on otolith shapes, the variation of otolith weight by sex, fish size, season, and sampling site, and the linear relationship between otolith weight and fish size. A total of 815 Periophthalmus chrysospilos specimens from Duyen Hai, Tra Vinh; Tran De, Soc Trang; Dong Hai, Bac Lieu; and Dam Doi, Ca Mau in the Mekong Delta ranged from 4.20 to 12.50 cm total length and from 1.26 to 16.88 g weight were analysed. The analysis results revealed that Ps. chrysospilos had a square otolith, deeply notched at the anterior apex and flat at the posterior apex. The weight of the left otolith showed a statistical difference according to survey factors, including gender, fish size, season, and sampling site. The otolith weight had a proportional relationship with to the total length, body weight, and head length of mudskippers (r2 =0.7~0.9), which meant that fish size could be predicted from the otolith weight and about 70-90% of the otolith weight of Ps. chrysospilos varied corresponded the growth of the fish.

“…Many studies have documented the relationships between otolith morphometry and fish size (e.g. Altin & Ayyildiz, 2018;Battaglia et al, 2015;Harvey et al, 2000;Iranmanesh et al, 2020;Oliveira et al, 2019). However, a study on the relationships of otolith morphometric parameters with body size is unavailable for the Coruh trout.…”

The Coruh trout (Salmo coruhensis Turan, Kottelat & Engin, 2010) is an anadromous species inhabit south and southeastern Black Sea basin. This study describes the allometric relationships between sagittal otolith (sagitta) measurements and total length (TL) of the Coruh trout collected from the Çam stream (Artvin, Turkey), and the length-weight relationship. A total of 82 individuals were caught with an electroshock device between May 2017 and April 2018. The length (LO), height (HO), weight (WO), perimeter (PO), and area (AO) of the otolith were recorded for each specimen. Shape indices such as form factor, aspect ratio, circularity, roundness, rectangularity, ellipticity, surface density were calculated using these otolith measurements. Relationships between otolith variables and the somatic growth of fish were defined by the curvilinear function (power model). An analysis of covariance revealed that these relationships did not differ between the left and right sides, and between females and males. All regressions were highly significant (P < 0.001) and mean percent prediction error values were less than 7 %. The relationships of LO, HO, WO, and PO against TL were negative allometric, while the TL-AO relationship was positive allometric. In the analysis of relationships between the otolith shape indices and TL, the values of form factor, rou ndness, and rectangularity indices decreased with fish somatic growth. In contrast, the circularity and surface density indices increased with fish body length. The length-weight relationship was obtained as W = 0.0155*TL 2.87 for overall samples. The difference between the slopes of LWRs of females and males was found insignificant. This study provides the first comprehensive data on the sagittal otolith morphometry of S. coruhensis.
