Researchers in the fishing industry are increasingly intrigued by the stressors that fishermen encounter in their profession and how they manage to reduce the harmful effects on their livelihood. Numerous studies have revealed that fishermen who depend on fishing for a living are now more susceptible to the fishery's unexpected developments. Livelihood stressors could be the main root cause for many of the major issues affecting the socioeconomic progress of the fishing community. However, a knowledge vacuum exists in the vulnerability and viability of the fishing occupation. Hence, this paper aimed to study 1. the vulnerability context of the marine fishermen of different sociodemographic characteristics, 2. how they buffer the negative effects on their livelihood and 3. the correlation between marine fishermen's livelihood from fishing and its viability. A sample of 308 marine fishermen from the Kanyakumari region of Tamil Nadu, India, was chosen for conducting an empirical inquiry. The researchers found that the marine fishermen in the age group of 46-60 years (M = 199.51, SD = 14.756) faced lesser occupational stressors than the fishermen of other age groups (M = 206.75, SD = 11.527; 206.87, SD = 14.890). Fishermen with higher education, by buffering the negative effects of such stressors, could make the fishing occupation more viable than fishermen with lower educational backgrounds. It was confirmed that fishermen's resilience increased with the level of livelihood stressors and that the more resilient they were, the more viable their fishing occupation was.
