Within India, Kerala, with a total terrestrial area of 38,000 sq km and a coastal line of 590 km, is a major exporter of fish and fish products. More than a million people from fishing communities live in 222 fishing villages in the State. This paper documents the activities and protests of Theeradesa Mahila Vedi, the women’s wing of Kerala Swathanthra Matsya Thozhilali Federation (fishworker’s union in the southern part of the state) since its inception. This organization has actively taken up issues that confront fisherwomen including labour discrimination between men and women, marginalization caused by changes in technology and competition in markets caused by globalization. The paper gives a historical narrative of the fisherwomen’s movement as it struggled with issues like denial of public and private rights; atrocities in the market created by local thugs, middlemen and moneylenders; constraints in mobility, health and family relations; anti-fishworker and anti-gender government policies, and violence and sexual harassment of fisherwomen and their girl children.
