The Covid‐19 lockdown in India in March 2020 revealed the presence of Adivasi communities in the marine fishing industry of Goa, a coastal state in India. While the migration for work of Adivasi communities from the central regions of the country is well recorded, their movement across geographies of the forest and the coast is relatively unknown. Working with initial data collected during the lockdown, interviews conducted after the pandemic and using secondary materials, the paper sought to understand the social and material conditions in the forest and the coastal regions that shape this movement. Centring the waged relation of Adivasi workers opened the door to thinking about the marine fishing sector in India as a capitalist industry, while paying attention to social reproduction highlighted how the coastal and forest regions are spatially linked through their movement and labour. This highlights that the coasts and forests are going through distinct processes of capitalist intensification and expansion. Making connections between ecological appropriation, historical processes of resource extraction and marginalization, the paper finds that the extraction of fish resources in Goa is made productive through the hierarchization and differentiation of Adivasi workers. It reveals how the social relations of identity and caste mediate access to and define conditions of work at sea.
