“…Due to the high economic importance of C . auratus as food and bait, several studies have been carried out worldwide, including on its age and growth (Hotos and Katselis, 2011), reproductive biology (Hotos et al ., 2000; Fazli et al ., 2008; Daryanabard et al ., 2009; Ghaninejad et al ., 2010; Bekova et al ., 2020; Hasanen et al ., 2021; El-Shenity et al, 2023), reproductive management (Quirós-Pozo et al ., 2023), population dynamics and stock assessment (Çiloğlu, 2023), and morphology and morphometry of saccular otoliths (Fortunato et al ., 2017; Ferri et al ., 2018; Çiçek et al ., 2020; Kesiktaş et al ., 2020; Reis et al ., 2023). However, few studies have been conducted on some aspects of this species in Tunisian and Mauritanian waters.…”

Saccular otoliths (sagittae) have long been shown to be species-specific and exhibit inland geospatial intra- and interpopulation morphological differences with variations in environmental conditions. Here, we analysed inland and outland geospatial variations in sagittae shape, length (Lo), width (Wo), perimeter (Po), and area (Ao), and fluctuating asymmetry (FA) in Chelon auratus males and females collected from Ghar El Melh (Tunisia) and Etoile Bay (Mauritania) stations to assess whether sagittae shape and morphometry differ between these two niches having different environmental conditions. At the intrapopulation level, a significant otolith shape asymmetry was observed between left and right and left–left and right–right otoliths among males and females of the Ghar El Melh (Tunisia) population and a significant symmetry among those of the Etoile Bay (Mauritania) population. At the interpopulation level, a significant asymmetry was found between left and right otoliths' shape among males and females of the two populations. Besides, a discriminant function analysis of otoliths' contour shape separated left and right otoliths among males and females at the intra- and interpopulation levels and also separated those of the two populations. Moreover, differential significant asymmetry in Lo, Wo, Po, and Ao between left and right otoliths was observed among males and females at the intra- and interpopulation levels. Therefore, the geospatial variations in environmental conditions between the two ecological niches effectively induced differences in otolith morphology. These significant asymmetries were discussed in terms of FA caused by environmental stress conditions resulting from variations in abiotic factors between the two ecological niches.

Reproductive biology of the Corsula Mullet, Rhinomugil corsula (Hamilton, 1822) (Mugiliformes: Mugilidae) was carried out based on 1166 (394 male and 772 female) fish samples collected monthly from the fishermen’s catch of Sitakunda coast of the Bay of Bengal, Bangladesh, from December 2016 to November 2017. Yearly male and female sex ratio were 1 : 1.96 (P < 0.01). In the male fish, immature, mature, and spent gonads were recorded as 69%, 27%, and 4%, respectively, while in the female fish, immature, maturing, mature, ripe, and spent gonads were recorded as 72%, 9% 11%, 5%, and 3%, respectively. First sexual maturity in male and female fish was attained at 16 cm and 21.5 cm length, respectively. The fish was a prolonged breeder with a peak in late monsoon. Highest GSI and GLI of male and female were recorded in September. Spawning season extended from July to November, and the peak was in September. Ova‐diameter ranged from 0.01 mm to 0.81 mm. Fecundity varied from 31488 to 251880 eggs/fish. Fecundity factor varied between 1099.09 and 2808.23 eggs/g of body weight. Relationships between fecundity and total body length, total body weight, ovary length, and ovary weight were highly significant (P < 0.01).
