TITLE:

Hematological Analysis of the Araguaia Dolphin (Inia araguaiaensis) in an Anthropized Environment in the Tocantins River, Pará, Brazil

KEY WORDS:

Hemogram, cetaceans, morphometry, dolphins

PAGES: 36
BIG AREA: Ciências Agrárias
AREA: Medicina Veterinária
SUMMARY:

Cetaceans of the genus Inia represent the largest freshwater dolphins in the world and exhibit great sexual dimorphism, being widely distributed in the basins of the Araguaia and Tocantins rivers, where they form groups and have a predominantly piscivorous diet. The frequent interaction between humans and dolphins, fueled by tourism, raises concerns about behavioral changes and the sanitary conditions of the places where the animals are found. The evaluation of the hematological parameters of the Araguaia dolphin in anthropized environments in the Tocantins River is relevant to assess the health of the species, identify physiological changes and provide scientific support. The objective is to evaluate the health of these animals, especially in environments impacted by humans. It is important for understanding the physiology of cetaceans, especially the Araguaia dolphin, a species that has still been little studied. With the help of a team of veterinarians and biologists, a capture strategy was developed that, due to the tidal regime, allowed only one animal to be captured per day. The captured animals included five males and two females, representing 42% of the population of dolphins visiting the site. Blood samples were collected and processed manually and automatically. The red blood cell count showed a mean of 3.56 ± 0.36, with hemoglobin levels of 12.76 ± 1.74 and hematocrit of 38.25 ± 5.19%. The platelet count showed significant variability, suggesting different immunological statuses among the individuals examined. The study also analyzed the biometrics of blood cells, involving a representative number. A total of 1600 red blood cells, 959 neutrophils, 1030 lymphocytes, 395 eosinophils, 104 monocytes and 1482 platelets were counted. Health monitoring is crucial to establish more comprehensive studies aimed at conservation and to understand how environmental changes can affect wildlife populations.
