Tharuvaikulam is a village in Thoothukudi District of Tamil Nadu in southern India. There are about 3,000, mostly Catholic, families living there. It falls under the Roman Catholic diocese of Thoothukudi and the feast of St.Michael is a popular religious festival.
Tharuvaikulam is located 10 km from Thoothukudi near the Bay of Bengal in Tamil Nadu.
Catholic settlement is believed to have started as early as 1750. At that time the village was located in Kaamanaikanpatti Parish and then in Vembar. In 1907 the present Taruvaikulam Parish was created.
Originally, people were fully dependent on palm trees and fishing. Later, in 1974, a match factory was built by Rev. Fr. Ambrose, providing jobs and income to thousands of villagers.
Fishing is the major industry, with fish such as tiger prawns and lobsters being mostly exported. Coral mining and diving for conches is also performed, though activity is declining. The government actively discourages these activities as Tharuvaikulam falls under the Gulf of Mannar Marine National Park.
A number of prawn hatcheries had sprouted up since 1990, but most shut down by 2000.
Salt mining is another lucrative industry. Production is mostly for industrial use.
Early in its history there was a flourishing trade in palm tree products which has gradually declined over time.
Agriculture is practiced on a small scale. Tharuvaikulam tomatoes are quite popular in the region. Red chilies are another favorite from the region. The vagaries of weather, however do not permit regular cultivation.
