Description Among the commercially important molluscs in
the Andaman and Nicobar Islands, Trochus nilotkuS
Linn6 and Turbo marmoratm Linne occupy a prominent
position because of their abtmdance and economic
value. Commercial exploitation of these shells may be
deemed to have started from 1929 (Panikkar, 1938)
although, even earlier to this, Japanese fishermen from
Singapore had been fishing for them around these
islands unauthorisedly (Rao, 1939). Of these two
species, Trochus niloticus was foimd to be more abundant
in all the islands surveyed. Though there were good
landings of these shells in the earlier years, they started
declining in later years, which prompted the Andaman
Administration to appoint a Special Officer to carry out
scientific studies on the fishery. A consolidated report
on the shell fishery of these islands during 1930-35 was
published by Rao (1939). Amirthalingam (1932), Setna
(1933), Prashad and Rao (1933,1934), Rao (1936 a,
b, 1937, 1941) and Panikkar (1938) made more
detailed observations on the shell fishery of the Anda-
mans, with accoimts of the feeding habits, breeding
seasons, size at sexual maturity, growth rate and other
biological details of T. niloticus. Anon (1939) has
briefly reviewed the results of the investigations made
by the Zoological Survey of India in Andamans. Menon
(1976), Cbatterjee (1976) and Appufcuttan (1977) have
described the importance of Trochus and Turbo in the
shell-craft industry. The Trochus and Turbo resources
of the different islands were surveyed during 1978
by the Central Marine Fisheries Research Institute,
the results of which, along with notes on the fishery,
are presented here.
