    The Gulf of Mannar and Palk Bay region are the primary areas for the Sacred Chank (Turbinella pyrum) resource along the south-east coast of India. Skin divers sell the live chanks to merchants who sort them based on size and quality. The fossilised gastropod fishery of T. pyrumexploited off the Tuticorin was commenced in 2009. The existence of fossilised chank resources was accidentally identified by fishers during the deepening of Tuticorin New harbour of V. O. Chidambaranar Port Trust (VOCPT) in Thoothukudi. Until 2013, exploitation of fossilized chanks was carried out by skin diving using sharp metal to find out the presence of chank which was time consuming. From 2014 onwards, the fishermen started using air compressor for locating and exploiting this resource more easily saving time.
