On the scarlet shrimp Plesiopenaeus edwardsianus (Johnson)
caught from the continental slope off Trivandrum,
southwest coast of India - an indication of a
potential deep-sea prawn resource
The Scarlet shrimp Plesiopenaeus edwardsianus (Johnson) is one of the larger species of the family Aristeidae known to be
widely distributed in the continental slopes of the tropical and subtropical belt of the Atlantic and also reported from the
Indo-West Pacific oceans. It contributes to commercial fisheries in some areas along the West African coast. The present
communication deals with the occurrence of this species in Bobbin Trawl operations off Trivandnim at 876-976 m depth in
the latter half of January, 1985. This is the first authentic report of the species from the Indian seas. While the catch in terms
of quantity may not be significant, it is felt that it is indicative of the presence of a larger population, which might sustain
a commercial fishery of this jumbo sized prawn. Taxonomy, distribution and available information on the existing
commercial fisheries of the species are given
