The groupers are among the fishes that are threatened globally due to their high economic value. However, their biological information is limited, including the white-edged lyretail (Variola albimarginata). The fish is considered as the least concern (LC) based on the IUCN category. The objective of the present study was to study some biological aspects of the white-edged lyretail harvested in the northern coast of Aceh. The fishes were collected in several fish landing sites (TPI) and fish market located in Banda Aceh and Aceh Besar District from June to August 2020. A total of 30 fish samples were collected in this study. The total lengths (TL) and weights (W) ranged between 14.30-36.02 cm and 33.2-581.6 g, respectively. In addition, 25 of collected fishes were female with the gonad maturity phases varied from one (1) to four (4) with the gonad-index (GSI) ranged between 0.1758-2.4038. The result of this study will be valuable in developing fisheries management and conservation of the species.

Considered as the least concern (LC) based on the IUCN category, the biological information of Epinephelus coioides is limited. The present study’s objective was to study some biological aspects of the orange-spotted grouper harvested in the northern coast of Aceh. The fishes were collected from June - August 2020 in several fish landing sites (TPI) and fish market located in Banda Aceh and Aceh Besar district. In total, 30 fish specimens were collected in this study. The total length (TL) of the fishes ranged from 194.1-237.6 mm. Also, the weight of the fishes ranged from 100.7-176.7 g. All the collected fishes were female with the gonad maturity levels in level one (1), with the average gonad weight of 0.01 g. This study provides a reference point of some biological aspects of the orange-spotted grouper that will help develop a practical fisheries management of the species.

Cephalopholis aurantia is one of the grouper species considered as the least concern (LC) based on the IUCN category. However, the data related to its biological features is limited. The present study’s objective was to study some biological aspects of the golden hind grouper harvested in the northern coast of Aceh. The fishes were collected from June - August 2020 in several fish landing sites (TPI) and fish market located in Banda Aceh and Aceh Besar district. In total, 24 fish specimens were collected in this study. All samples were small and young (between 103.1-240.0 mm TL and 60.6-267.5 g). In addition, all the collected fishes were female with the gonad maturity levels varied from stage I to stage IV with the gonad weight ranged from 0.01-2.00 gr. This study is providing baseline data of some biological aspects of the golden hind grouper that will be valuable in developing a practical fisheries management of the species.
