1916

The remarkable value of oysters in the promotion of digestion is due in part to the stimulating influence of the salts contained in their liquor and in their tissues and partly to the variety of powerful ferments present in the digestive gland, often miscalled the liver," so conspicuous as the brownish tissue occupying the centre of the body mass. [...] The date of the re-population of our pearl banks with pearl oysters depends upon three factors, (a) the number of adult pearl oysters scattered about among the coral reefs and rough hard bottom close inshore adjacent to the banks, or upon the banks on the opposite coast of the Gulf, (b) the occurrence of a favourable surface drift from the place where adult oysters are to the region of the pearl b [...] To test the value of this deduction and to further elucidate this question of the inter-relationship of the pearl banks on the opposite sides of the Gulf, I began experiments in 1907 ; between 1st November and 2nd December I set free zoo bottle drifters when on inspection duty on the Ceylon pearl banks while 279 others were liberated off Tuticorin and elsewhere by the courtesy of the Commanders of [...] The trawl skipper of the Violet returned to port enthusiastic over the trawl potentialities of the Cape Comorin bank of soundings both in regard to the large quantities of good quality fish to be had there and to the clean and unobstructed nature of the bottom. [...] This agrees precisely with the results obtained by the Violet and makes it clear that the Cape Comorin banks are the notable resort of multitudes of bottom feeding fishes in contra- distinction to the migratory shoals of more active fishes which, on the Malabar coast and in Palk Bay, prefer to seek their living in the upper horizons of the sea rather than hunt along the bottom.
