AVILA-TORRES, Ignacio; MORENO, Mariel  and  CUBILLA, Fernando. New records and first approach of fish richness in the inland waters of the Yacyretá Nature Reserve. Rep. cient. FACEN [online]. 2021, vol.12, n.2, pp.110-116. ISSN 2222-145X.

The Yacyretá Nature Reserve (YNR) is located in the extreme south of Paraguay, to the west of the Yacyretá dam, covering approximately 8,481 hectares. It has lagoons of artificial origin of permanent water, as a result of the removal of earth material for the construction of the Yacyretá Binational Dam on the Paraná River. The objective was to survey the fish fauna present in the inland waters of the YNR. The study was carried out in three sampling stations in internal waters of the YNR developing a single fishing campaign, during the days 16 to 18 September 2017. Eleven species were collected, resulting in 8 new records for the YNR, Corydoras undulatus, Hyphessobrycon eques, Astyanax bimaculatus, Curimatopsis myersi, Pirrulina australis, Hoplerythrinus unitaniatus, Rivulus punctatus y Letacara dorsigera.

Keywords : Ichthyology; Neotropical region; artificial lagoons; Yacyretá Island; Paraguay.
