Abstract

Deep-sea prawn records from Indian waters date back to early 20th century from the surveys of the RIMS Investigator, University Research Vessel Conch, M. V. Kalava and Varuna followed by the Indo-Norwegian Project, FORV Sagar Sampada off the Southwest Coast of India. The distribution of deep-sea prawns was recorded upto Ratnagiri (lat.16° N) with maximum concentration in the Quilon Bank (lat. 8°- 9°N). The enterprising small and medium prawn trawler operators of Kerala ventured into deep sea fishing for the first time in November 1999 with an annual average estimated landings of deep-sea prawns of 11315 t during 1999-2020 while 9137 t during 2007-2020 from the MDTN at a depth of 200-500 m. The species composition showed the dominance of M. andamanensis (27.6%) followed by A. alcocki (20%), P. quasigrandis (19.9%). H. chani (17.6%), H. woodmasoni (9.4%). Mitochondrial sequences (COI, 16S, and Cytb) of deep-sea prawn records were deposited in NCBI GenBank for accession numbers.
