In Cabo Verde, 190 fishers from seven of the archipelago’s 10 islands volunteer with the Guardians of the Sea program, reporting illegal practices and sightings of marine megafauna as they go about their daily fishing work.Their presence at sea acts as a strong deterrent against illegal activities and raises awareness among other fishers about the importance of long-term, sustainable marine management, according to a program co-founder.Fishers have always been a pillar of Cabo Verde’s economy and identity. The country hosts a fleet of approximately 1,535 vessels, ranging from artisanal to semi-industrial, and the sector provides a livelihood for coastal families.

FOGO, Cabo Verde — Alberto Martius had just returned to shore in his white and blue wooden boat with his 18-year-old son, Leandro. The pair had been fishing off their home island of Fogo in the Cabo Verde archipelago off northwestern Africa. While out, they were also keeping an eye on the sea.

“I’m proud my son is following in my footsteps, protecting the ocean,” Martius told Mongabay. “I feel I’m doing the right thing to protect the sea. Almost every day, I’m patrolling this area to monitor marine animals and make them return as numerous as they were when I was a little kid.”
