The hydrographic basin of the Doce River has a long history of environmental degradation that reached its peak in 2015, with the disruption of the iron ore tailing dam owned by mining companies. Despite the complexity of the scenario, significant efforts in studies are being made for this area. However, given the extension of this water system, its biological diversity and intensity of degradation have been subjected to it, much remains to be done for its conservation. It is necessary not only studies in the field of biology but also information campaigns about that system. This master's research was developed to contribute in some way to a change in this situation. It aimed to combine scientific knowledge with the arts through the scientific illustration of endangered fish species that occur in the middle stretch of the Doce River basin, thus promoting detailed documentation based on a visual representation of its ichthyofauna. To this end, species with officially endangered conservation status were investigated. The initial selection was done based on publications that listed the species found in the river. The final list of six threatened fishes was defined after being submitted to selection criteria considering the information provided by specialists. The selected fishes were studied at the theoretical and observational levels, based on scientific literature, photographic image analysis, observations of some species preserved in museums and information collected from experts. Therefore, in addition to the literature review and theoretical research, this dissertation is composed of a practical component that stands out for its originality, since, as far as we know, after extensive investigation, no similar research that focuses on coherent and systematized documentation of threatened fish from this basin through scientific illustration has been found. At first, the execution of preliminary drawings was the main task that later was structured into a series of schematic drawings. Thus, an image for each species studied was developed resulting in the precise and rigorously scientific structure of what would be an ideal specimen. Regarding the typologies, the representation of the fish in the main view was adopted. But in some cases, it was also presented detailed views. In short, it is expected that the illustrations resulting from this investigation can help in the propagation of science to various audiences, fulfilling the didactic role of scientific illustration.Therefore, this work aims to help in the knowledge and preservation of the memory of ichthyological biodiversity, serving as a basis for a future iconography project of fishes from the Doce River basin.
