Chank resources of India

Nayar, K Nagappan and Mahadevan, S (1973) Chank resources of India. In: Proceedings of the symposium on living resources of the seas around India, 1968, Mandapam Camp.



The sacred chank Xancus pyrum (Linn.) is a commercialJy important gastropod fished in large numbeis along the coasts of all but a few of the maritime states of India. Fishing is carried out mainly by skin diving, although hand-picking and net fishing are also prevalent here and there. The fishery provides a good source of living to nearly 1,000 divers in the Madras State in addition to those engaged in the same profession along the Gujarat and Kerala coasts. The main market for these chanks is West Bengal where chank bangle industry is flourishing. Investigation conducted by means of SCUBA by the authors have brought to light good concentration of chank population suitable for commercial exploitation, over vast stretches in the Palk Bay and Gulf of Mannar. The statistics of annual chank landings, yield from area to area, account of the chank fishery in important centres, details of the diving method and the extent of the chank grounds are recorded. Possibilities for exploiting unfished areas and suggestions for increasing the fishing tempo are discussed in detail. In this context SCUBA diving for chanks has proved very advantageous and is recommended keeping in view the economic aspect of the divers as well as judicious exploitation of the stock.
