Abstract. Malik MDA, Putra MIH, Topan E, Pertiwi NPD, Artiningsih EY, Sari SK, Lewis S, Prabuning D, Sembiring A. 2022. Short Communication: Genetic variation of oceanic manta ray (Mobula birostris) based on mtDNA data in the Savu Sea, Indonesia. Biodiversitas 23: 1700-1706. The Savu Sea, one of Indonesia's top conservation priorities, is home to various marine charismatic species, including the oceanic manta ray (Mobula birostris), whose conservation status is currently endangered and is protected by the Indonesian government. However, due to domestic and global demand for its fishery products, as well as shortcomings in fisheries management, this species is still poached and bycaught in the Savu Sea. Understanding their population structure is important to achieve effective conservation and fisheries management strategies that will have a positive impact on preserving their population in this area. This study aims to reveal the genetic variation of oceanic manta rays in the Savu Sea. Thirty samples from three locations in the Savu Sea were successfully preserved from East Flores (24), West Manggarai (4), and Rote Ndao (2) and then analyzed using ND5 locus from Mithocondiral DNA (mtDNA). The result indicated a close genetic relationship between three locations (East Flores, West Manggarai, and Rote Ndao) based on the phylogenetic tree and Analysis of Molecular Variance (AMOVA) result with value of 0.05158 (P-value = 0.62268) indicated as a single population. In conclusion, the findings of this study provide some insight into the possibility of manta ray populations in the Savu Sea having strong connectivity between areas, which is critical information for regulators and managers to integrate conservation and management strategies within the Savu Sea.

Abstract. Wardana ED, Putra ING, Al Malik MD, Yusmalinda NLA, Ningsih EY, Pertiwi NPD, Salim MG, Kanedi MM, Putra MIH, Sembiring A. 2023. Population genetic structure of the bentfin devil ray (Mobula thurstoni) in the South Indonesia Sea with limited sample based on ND5 gene. Biodiversitas 24: 3743-3749. Bentfin devil ray (Mobula thurstoni) is one of five Mobula rays with a worldwide distribution. This species has high economic value and play an essential ecological role. However, due to their biological characteristics, such as low reproductive rates and late maturity, these species are highly vulnerable to overfishing and slow to recover from depletion. Genetic information, such as this species's population structure and genetic diversity is limited. This study aimed to determine the genetic variation and population structure of M. thurstoni in the South Indonesia Sea based on mitochondrial DNA from ND5 gene. Twenty-two samples of M. thurstoni were successfully collected from three locations Palabuhanratu (n=5), Muncar (n=13), and Savu Sea (n= 4). The haplotype diversity (Hd) ranged from 0.782 to 1.00 (mean=0.839), and Nucleotide diversity (?) ranged from 0.004 to 0.018 (mean=0.007). Then, no significant population differences (P-value > 0.05) were observed between locations, indicating that M. thurstoni population in the South Indonesian Sea represents a single genetic population. Additionally, the haplotype distribution also indicated the presence of two shared haplotypes between locations. Consequently, co-management strategies for sustainable fishing and conservation must be implemented across these three locations to ensure the sustainability of this species in the nature habitat.
