Sreejaya, R (2008) Studies on spawning and larval rearing of the Whelk, Babylonia spirata (Linnaeus,1758) (Neogastropoda: Buccinidae). ["eprint_fieldopt_thesis_type_phd" not defined] thesis, Central Marine Fisheries Research Institute. Submitted to Cochin University of Science and Technology.
The spiral Babylon Babylonia spirata (locally called ‘Dove egg shell’- Pravumutta chank) is a gastropod resource which is being exploited rapidly for export to foreign countries mainly to Japan. The meat of this whelk is exported and also consumed by the fisher folks on the southeastern coast of India. The shells of these snails are used in the lime industry and for ornamental purposes. The operculum is exported to foreign countries for manufacturing medicine and perfumes (Thirumalavalavan, 1987). The export of these molluscs has led to the development of active fishery of this shellfish in different parts of India. As the demand for the whelk meat is increasing day by day and intensive exploitation is done by trawling in most centers, the chances of overexploitation and exploitation of undersized whelk leading to the depletion is quite possible. Measures are to be taken to avoid overexploitation and indiscriminate exploitation of the juvenile whelks and egg masses from the natural beds. Appukuttan and Ramdoss (2000) stressed the need for judicious exploitation and hatchery seed production for sea ranching to augment the production of the species.
