The exposure of humpback whales (Megaptera novaeangliae) to anthropogenic impacts is increasing due to population recovery following the legal ban on commercial whaling, together with the increment of human activities at the species breeding grounds. The proposed research aims to investigate the health of the population of humpback whales that seasonally migrate to the southeastern and northeastern Brazilian coast, as well as to quantify the occurrence of anthropogenic interactions, detrimental to the species. The evaluation will be made from images obtained for photo-identification of whales in the wild, through which skin lesions and scars will be identified, and anthropogenic marks will be quantified, providing information on individuals who survived to entanglement in fishing gear, collisions with vessels and/or interactions with predators. When possible, skin samples will be collected and processed according to routine histopathological techniques to search for possible etiologic agents and pathogenic factors in order to correlate them with skin diseases observed in the analysis of images. Special tissue staining methods as well as immunohistopathological and/or molecular techniques may be used when appropriate and feasible. It is expected that the results of this study provide important indicators of environmental conditions where the humpback whales live and contribute to guide management and conservation actions for the species.
