Abstract

Based on the exploratory trawling surveys for a 10-year period from 1961
to 1970 by the Government of India trawler, M. T. Ashok, in the northwestern
regions of the Bay of Bengal between the latitude zones 16°40' and 21°10', the
magtutude of the demersal resources has been estimated by the 'swept area'
method. For an arefi of 41,478 sq. km. a fishery resource of 4,18,682.45 tonnes
with 2,51,209.45 toijnes as the estimated potentially sustainable yield at the 60%
level, is estimated. The present estimates have been compared with those reported
for Goa to demonstrate the richness of the continental shelf along the Andhra-
Orissa coast for ground-fish fisheries.
