“…Groupers like Areolate grouper have fallen prey to over‐exploitation primarily due to their desirability in the seafood market (Yusuf et al, 2023). Groupers are highly prized for their large size, delicious taste, and firm texture, making them lucrative targets for commercial and recreational fishing industries.…”

The objective of this study is to provide information on the reproductive biology of tomato hind grouper, Cephalopholis sonnerati (Valenciennes, 1828) for conservation and management purposes. Fish caught by artisanal fishermen from September 2019 to August 2021 were analysed. A total of 280 females, 31 males, and 4 transitional and 178 sex‐undetermined fish were analysed. The female to male sex proportion was 9:1, and the fish reached a maximum total body length of 38.5 and 54.5 cm for females and males, respectively. The following microscopic stages were identified: immature, developing, ripe, running ripe/releasing, and spent in both males and females. Several asynchronous development patterns were observed in the studied gonads, including multiple oocyte stages and early and advanced stages of sexual transition. High gonadosomatic index (GSI) for both males and females was recorded in March, May, and November. Running ripe and releasing stages in females were identified in the months from March to June, which indicates the spawning season. The absolute and relative fecundity of the species ranged from 162,723 ± 207,267 and 239 ± 285, respectively. An exponential relationship was found between fecundity and total body length (TL), fecundity and total body weight (TW), and fecundity and gonad weight (GW).

Grouper (subfamily Epinephelinae) is one of the largest groups of fish in the oceans. Identification of groupers, especially the Epinephelus, is conducted based on morphological characteristics (color, pattern, body shape, and size. However, the identification process is difficult to differentiate morphologically because of their similar characteristics. One method that can be applied is DNA barcoding. This study aimed to compare groupers from Saudi Arabia and Indonesia. Morphological and molecular identification results show that the grouper from this study (from Yanbu, Saudi Arabia, and Lamongan, Indonesia) was Epinephelus areolatus (areolate grouper). Morphologically, grouper samples from Yanbu (Saudi Arabia) were as follows: dorsal fin X-XI/12-15; anal fins II-III/8-9; pectoral fins 13-15; pelvic fin I-5; lateral line scales 48-53; vertebrae 24. Meanwhile, the meristic results of groupers from Lamongan (Indonesia) were as follows: dorsal fins X-XI/15-17; anal fins II-III/8; pectoral fins 16-19; pelvic fin I-5; lateral line scales 48-53; vertebrae 24. The morphological differences between E. areolatus from Saudi Arabia and Indonesia were its spots and caudal fin. Molecular results on E. areolatus showed different clades. Samples from Saudi Arabia belonged to the Western Indian Ocean clade while Indonesia belonged to the Western Pacific. This showed that there were morphological and molecular differences between E. areolatus from Yanbu (Saudi Arabia) and Lamongan (Indonesia). The COI gene sequences of areolate grouper were submitted to NCBI (accession number PP388919.1 for Lamongan and PP388920.1 for Saudi Arabia). This research data can be used as a reference for conservation.
