A woman uses hand tools to chip out oysters at exposed rocks on the beach of Morjim, Goa, India. Rock oyster harvesting can be a local sustainable food and sovereignty solution. Aaron Savio Lobo studies oysters and according to his studies, both men and women in Goa harvest - but differently. Women chip on the rocks while men dive into the sea to bring a bunch of oysters. These practices are kinder to the sea bed as men use gloved hands to sift through the bed compared to using trawler nets that destroy the bed along with other sea species. Women take the job of taking out the oyster meat, cleaning and discarding the shell back into the ocean.
