Ocurrence and physiological parameters of freshwater stingrays from the Uatumã river basin in the Amazon

Freshwater stingrays are naturally endemic to South America, and the Amazon region is home to the most incredible diversity; however, areas still lack biological information about this group of elasmobranchs, including the Uatumã River, Amazonas, Brazil.

CIENCIAS AGRARIAS Blood Conservation Dorsal coloration Ecology Elasmobranchs Freshwater stingrays are naturally endemic to South America, and the Amazon region is home to the most incredible diversity; however, areas still lack biological information about this group of elasmobranchs, including the Uatumã River, Amazonas, Brazil. The present work aims to establish the occurrence and physiological parameters of four freshwater stingrays from the Uatumã river basin, Amazonas, Brazil. To this end, stingray collections were carried out in three municipalities bathed by the Uatumã River: Presidente Figueiredo, Itapiranga and São Sebastião do Uatumã. The stingrays were captured through fishing using a hand net, and after capture, the rays were anesthetized, and blood was collected to determine erythrogram and plasma biochemistry values. After blood collection, the captured specimens were identified based on the disc's dorsal and ventral color pattern, the presence or absence of the labial groove and the row of spines on the tail; they were also measured, weighed and sexed. In total, 69 freshwater stingrays were captured, 59 of which were from the Potamotrygon genus and ten from the Paratrygon genus. Most of the individuals captured were young, and the most common species was Potamotrygon orbignyi, which had a reticulated color pattern. Regarding physiological parameters, the values found for the erythrogram and plasma biochemistry were similar to those found in other studies in the Amazon basin. This study provides essential information about the biology of four freshwater stingrays found in the Uatumã river basin, contributing to scientific knowledge, management and conservation of these species, which are fundamental to the Amazon aquatic ecosystem. As arraias de água doce são naturalmente endêmicas da América do Sul, e a região Amazônica abriga a maior diversidade, porém, ainda existem áreas carentes de informações biológicas sobre esse grupo de elasmobrânquios, dentre esses locais, encontra-se o rio Uatumã, Amazonas, Brasil. O presente trabalho tem como objetivo estabelecer a ocorrência e os parâmetros fisiológicos de quatro arraias de água doce da bacia do rio Uatumã, Amazonas, Brasil. Para isso foram realizadas coletas de arraias em três municípios banhados pelo rio Uatumã: Presidente Figueiredo, Itapiranga e São Sebastião do Uatumã. As arraias foram capturadas por meio de pescarias usando rede de mão e após a captura, as arraias foram anestesiadas e foi realizada a coleta de sangue para posterior determinação dos valores do eritrograma e da bioquímica plasmática. Após a colheita de sangue os exemplares capturados foram identificados com base no padrão de coloração dorsal e ventral do disco, na presença ou ausência do sulco labial e na disposição da fileira de espinhos na cauda, além disso, foram medidas, pesadas e sexadas. No total, foram capturados 69 espécimes de arraias de água doce, sendo 59 do gênero Potamotrygon e 10 do gênero Paratrygon. A maioria dos indivíduos capturados eram jovens e a espécie mais comum foi a Potamotrygon orbignyi com o padrão de colorido reticulado. Em relação aos parâmetros fisiológicos, os valores encontrados para o eritrograma e bioquímica do plasma foram semelhantes aos encontrados por outros estudos na bacia Amazônica. Este estudo fornece informações importantes sobre a biologia de quatro espécies de arraias de água doce encontradas na bacia do rio Uatumã, contribuindo para o conhecimento científico, para o manejo e a conservação dessas espécies que são fundamentais para o ecossistema aquático amazônico.

description Freshwater stingrays are naturally endemic to South America, and the Amazon region is home to the most incredible diversity; however, areas still lack biological information about this group of elasmobranchs, including the Uatumã River, Amazonas, Brazil. The present work aims to establish the occurrence and physiological parameters of four freshwater stingrays from the Uatumã river basin, Amazonas, Brazil.
