Abstract

Protection of the desert pupfish (Cyprinodon eremus) in the Sonoyta River, as an educational project at the Sonoyta State High School. In response to this need, the conservation project emerged, creating a network of refuges (ponds) for the protection, recovery, and reintroduction of native freshwater species of the Sonoyta River. These refuges are recognized as ex situ conservation sites. The decision to build a pond at the Sonoyta COBACH was based on its permanent protection, its location in the species’ natural range (near the Sonoyta River), and its role as an educational space to raise awareness about the value of these native species. Initially, the pond housed three endemic species: the desert pupfish (C. eremus), the green-bellied turtle (Agosia chrysogaster), and the sandhill turtle (Kinosternon sonorense); however, the only species that survived over the years was the desert pupfish. The project aims to ensure its protection, conservation, and publicity, so that it is known, respected, and creates pride in the community. It demonstrates its sustainability, as for more than 17 years, its population has remained stable and increased considerably without undergoing any morphological or apparent genetic changes. The project is a clear example that the only way to transform society is through education.
