Abstract. Kanedi MM, Wijayanti DP, Widowati I, Malik MDA, Yusmalinda NLA, Sembiring A. 2023. Genetic diversity of bigeye thresher shark (Alopias superciliosus Lowe, 1841) landed in Palabuhanratu Fishing Port, Sukabumi, West Java, Indonesia. Biodiversitas 24: 3488-3494. The Alopias (Lowe, is a highly migratory marine shark, widely distributed globally tropical and temperate seas. listed as Vulnerable/VU species on the red list International Union for Conservation Nature (IUCN) Appendix II Convention Trade Endangered Species Wild Fauna Flora (CITES). Genetics substantial essential approach to conservation, management, sustainability. This study investigates shark’s genetic structure populations that Samples were collected (n=16) secondary data from Atlantic Ocean (n=212) Indian sequences obtained GenBank. A total 16 have been amplified using mitochondrial DNA control region (dloop) with 857 bp size sequenced. result showed haplotype value (Hd=0.86667; ?=0.01048) considered high value. Overall, AMOVA FST results significant differences population between Palabuhanratu, Atlantic, an 0.04420 (p-value <0.05). Based result, effective strategy needed manage sharks, both government private sector.
