Abstract

Length-weight relationship was estimated for the deep-sea congrid eel species collected from the trawler landings at Kalamukku, of Kochi, Kerala and Colachel, of Kanyakumari, Tamil Nadu, Arabian Sea, southern India, between February 2021 and August 2022. The samples were obtained from the deep-sea trawlers, operated along the Exclusive Economic Zone of India, Arabian Sea with a cod end mesh size of 35 mm at 200–250 m depth. The estimated b values range from 2.80 to 3.19. Novelty of the study is providing length-weight relationship for two newly described eel species viz. Ariosoma indicum and A. maurostigma will help in the conservation and management of these species in the future.
