Record of morphological deformities in Corydoras aff. longipinnis in two reservoirs under urban influence in Upper Iguaçu and Southern Coastal basins in Paraná State, Brazil

Abstract In this work we report on the presence of morphological deformities in Corydoras aff. longipinnis from two reservoirs in Paraná State, Brazil. The frequency of deformities in the fish populations was 11% in Iraí and 10.5% in Capivari reservoirs. Considering that the frequency may be associa...

Zusammenfassung:Abstract In this work we report on the presence of morphological deformities in Corydoras aff. longipinnis from two reservoirs in Paraná State, Brazil. The frequency of deformities in the fish populations was 11% in Iraí and 10.5% in Capivari reservoirs. Considering that the frequency may be associated with impacts caused by anthropic activities, this information can be used as a metric in management systems and environmental monitoring. Resumo Neste trabalho relatamos a presença de deformidades morfológicas em Corydoras aff. longipinnis de dois reservatórios no estado do Paraná, Brasil. A frequência das deformidades observadas nas populações analisadas foi de 11% no reservatório de Iraí e 10,5% no reservatório de Capivari. Considerando que a frequência pode ser associada a impactos causados por atividades antrópicas, essa informação pode ser usada como uma métrica em sistemas de gestão e monitoramento ambiental.
