Abstract

Knowledge of freshwater stingrays' physiological parameters is essential for conserving elasmobranch diversity. This study aims to characterize the erythrogram and plasma biochemistry of freshwater stingrays from the Uatumã River basin for the first time. Specimens were captured in Presidente Figueiredo, São Sebastião do Uatumã, and Itapiranga, Amazonas, Brazil. Blood samples were collected from 69 stingrays and processed to obtain blood values. The species Potamotrygon orbignyi, Potamotrygon motoro, Potamotrygon scobina, Potamotrygon marquesi and specimens of the genus Paratrygon were identifield. Neonates and P. marquesi individuals were found was Itapiranga. At this stage, the blood profiles of P. orbignyi and P. scobina rays were lower than those of young, adult, and subadult individuals. The results were similar across locations, species, and existing data from the Amazon basin. The study provides a basis for future research on stingrays in the Uatumã River basin.

摘要

了解淡水黄貂鱼的生理参数对于保护软骨鱼类的多样性至关重要。本研究旨在首次描述乌阿图马河流域淡水黄貂鱼的红细胞图和血浆生化特征。样本采集于巴西亚马逊州的菲格雷多总统城、圣塞巴斯蒂昂·杜乌阿图马和伊塔皮兰加。从69条黄貂鱼身上采集血液样本并进行处理以获取血液值。鉴定出了奥氏河魟、珍珠魟、史氏河魟、马克氏河魟物种以及副河魟属的样本。在伊塔皮兰加发现了新生幼体和马克氏河魟个体。在此阶段，奥氏河魟和史氏河魟幼体的血液指标低于幼年、成年和亚成年个体。不同地点、物种以及来自亚马逊河流域的现有数据的结果相似。该研究为未来对乌阿图马河流域黄貂鱼的研究提供了基础。
