project-piaba:Sustainable collection of cardinal tetras from the Aquarium Fishery of Barcelos. Each year, the river goes through a low water season, when the vast majority of these fish die. Collection occurs when the water recedes and has no impact on the populations of these fish the next season. The fishery has a large positive impact on the environment, as it provides jobs for the locals of Barcelos who would otherwise have to turn to occupations that would harm the environment. -- source link
