- The demise of the pearl fisheries in Tuticorin, Tamil Nadu (India): social and biological aspects and their application towards a sustainable management for the chank fisheries and condition improvement of the associated diver fisherfolkPublication . Santos, Sara Vanessa Freitas da Silva; Erzini, Karim; Bavinck, MaartenGlobally, changes are being felt in the fisheries sector, with a strong drive for maximizing catches on one hand and lack of resilience and recovery of stocks on the other. In India, too, habitat loss and reduced resource abundance are contemporary issues of concem, with great focus being put on the fishing populations dependent on the sea for maintaining a livelihood. Tuticorin is a coastal city of the south-eastem state of Tamil Nadu which supports a strong fishing tradition and, historically, is the centre for the world-famous pearl fisheries. These treasures of the sea are collected by divers who depend on the catch of an altemative resource - the sacred chank Xancus pyrum - for their regular source of income. At present, the pearl oyster Pinctadafucara can not support a fishery and chank stocks are also suffering accentuated declines. The divers of Therespuram fishing village, where the greatest percentage ofthese professionals can be found today, convey disappointment towards their current conditions and show concem for their future and that oftheir descendents. The pearl fisheries were taken as a case study in the present document and were used for the purpose of creating a base of foundations which, in tum, was put to practice through the suggestion of basic management strategies for the chank fisheries, throughout which the diving community was given utmost importance. The major part of the information narrated throughout this thesis was obtained through the accounts of divers, with the research taking the fonn of a qualitative social study.
