FISH SPECIES 50

A group of researchers and students from the Faculty of Sciences undertook the first study of spider species in the Esteros y Algarrobales del Río Uruguay area In just two sample collection campaigns, five priority species for conservation were identified. The Prodidomidae family was recorded for the first time and seven new species for the country were named, one of which belongs to the Prodidomidae family. We implemented the first fish survey (ad hoc) in the Esteros y Algarrobales del Río Uruguay area The project was led by researchers from the River Ecology Pole of the CENUR-UDELAR and took place in the Amarillo Stream that runs through the protected area. The monitoring activities concluded that the Amarillo Stream is an area with considerable fish diversity with 47 registered species, 18 of which have been classified as a priority for conservation.
