Fishers use cell phones to demonstrate the impact of dams on migratory fish in the Bolivian Amazon
Fishers from the town of Puerto Villarroel, located on the shore of an Amazonian headwater of the Mamore river in Bolivia, record with their cell phone each observation of goliath catfish (locally called ¨dorado¨). This species is in danger of extinction in Bolivia. "Before we caught this species frequently in the Ichilo River, every year between October and April, nowadays there is no longer any, the species has disappeared after the construction downstream of two hydroelectric dams in Brazilian territory¨. Omar uses the application ICTIO, developed by the Citizen Science Project of WCS, and introduced in this area by FAUNAGUA and WWF, to record his catches and give early warning when something goes wrong with the fisheries resources, as now is the case with the goliath catfish. His testimony can be watched in the following link: https://youtu.be/fj7I2VJ6uyY.
GOLIATH CATFISH IS THE SPECIES THAT MIGRATES THE LONGEST DISTANCES IN FRESHWATER ON EARTH: LARVAE DRIFT 4 000 KM DOWNSTREAM AND PRE-ADULTS MIGRATE 4 000 KM UPSTREAM TO SPAWN IN AMAZON HEADWATERS.
