This chapter analyzes the petroleum industry impact on a fishing community of Puerto Ceiba, Mexico. Traditionally, a key economic activity, fishing is experiencing a crisis of generational renewal marked by a series of economic, social, and educational factors. A qualitative ethnographic study conducted in 2023—employing in-depth interviews, participatory mapping, and field diaries—reveals that local youth increasingly pursue careers in the oil sector, drawn by its promise of economic stability. This tendency exists in an educational system that has come to be articulated with industry and has abandoned training in fishing activities, despite doubts about job security in the petroleum sector. I conclude that prioritizing the oil industry has reconfigured the educational and professional aspirations of youths and displaced fishing as a viable option. In this context, I propose: (a) adopting the “ethic of possibility,” a conceptualization that seeks to construct alternative futures that are more hopeful by revaluing fishing; and (b) adapting international experiences through training and support for new generations. The situation described reflects a complex interaction among several factors that have changed young people’s professional perspectives by privileging the stability that the oil industry offers compared to the fishing tradition.
