A study of the fishery and estimation of relative abundance of ground fish off cochin.

Attempts to explore the fishing grounds off Cochin made in October 1923 by 'Sea Scout', a powerful sea-going launch belonging to the Government of Madras (under the command of Capt. Crib), "proved a disappointment from the start both in design and equipment for fishing with a Danish seine net" (Gravely, 1929). Again, in 1928 'Lady Goschen'. another Madras Government vessel, carried put exploration 33 miles west and south-west off Cochin in depths ranging from 31 to 35 fathoms (Sunder Raj, 1930). Later, during September 1952. 'Tai-o-Maru' of the New India Fisheries Co. conducted some trawling between 13 and 26 fathoms north,-west of Cochin (George 1952). The results of these trials were not very encouraging
