The Rolex Awards 2019 laureate, wants to save the arapaima fish population in the Amazon. Is it an uphill challenge?
Looking at João Campos-Silva, three words—big, friendly, giant—come to mind. The Brazilian conservationist and fisheries biologist, who was one of the five laureates unveiled at the Rolex Awards for Enterprise (RAE) 2019 ceremony held in Washington in June this year, is tall and burly but always speaks in a calm and collected manner. (The other four laureates include French medical scientist Grégoire Courtine, Ugandan IT specialist Brian Gitta and Canadian entrepreneur, Indian conservationist Krithi Karanth and molecular biologist Miranda Wang.)
In his usual mild-mannered way, he presented his case at the National Geographic Explorers Festival held in conjunction with the RAE awards ceremony to fellow explorers and conservationists among many others in the environment and sustainability spheres. Referring to the arapaima, the largest scaled freshwater fish in the world, he said: “It’s very large—up to 3 metres—and can reach 200 kg. It has played a central role in feeding Amazonian people since the development of the first human society in the region.” But due to overfishing, habitat fragmentation and various human impacts, the arapaima's population is dwindling and Campos-Silva wants to save it as well as the livelihoods, food supply and culture of rural communities in Amazonia who depend on the region’s rivers for their survival.
