Every year some traditional fishermen from
Kanyakumari migrate to Tuticorin with their
catamaran craft to fish with various gears
according to availability offish groups in the area.
During 1988 these fishermen developed a nylon
fish net with 4 to 5 cm mesh size to catch large
quantities of Hilsa toli Fowler locally called 'Kalar'
available near the Hare Island fishing grounds at
depth range from three to four metres
