Abstract

Nemipterus randalli is one of the most commercially important fish species along the Indian coast. Specimens were sampled from Visakhapatnam, northern Bay of Bengal, along the east coast of India. We analysed the data generated in the present study with previously available sequences from the Arabian Sea, Bay of Bengal, Red Sea and the Mediterranean Sea. Intraspecific variation in COI sequences between the Visakhapatnam and other locales varied from 0.7–1.1%. Also, analysis of D-loop sequences revealed deep genetic divergence with high pairwise ΦST values (0.77–0.89). Results identified a distinct population of N. randalli from Visakhapatnam. To conserve genetic integrity, special attention and detailed studies are needed on the Visakhapatnam population of N. randalli in the northern Bay of Bengal.
