Studies related to fish diet contribute to the knowledge of biology species, in addition to assisting in the investigation of trophic ecology, competition and fish predation. In the Pantanal, there are signs of anthropization in the environments, which affect mainly fish populations, including bare in environments natural that can cause exaggerated caloric gain, being harmful to health of fish. The objective of this work, divided into 2 chapters, was to analyze the diet of Brycon hilarii (Valenciennes, 1850), during the four hydrological periods, verifying the ecological relationships of the specimens collected in the stretches of Rio Paraguay/Porto Estrela, Sepotuba River and Taiamã Ecological Station (EET). Was sampled a total of 558 copies in monthly campaigns, during the four periods of the hydrological cycle in the year 2013 to 2015 for article 1 and in the year 2019 to 2020 for article 2. The specimens were captured with bamboo poles, hook, line of different measures and natural baits. Then packed in boxes and sent to the laboratory, where the data were measured biometrics and stomachs removed for analysis. The results of the first article, show that Erythrina fusca Lour. (zucchini), is the main food item of the diet of B. hilarii. During the flood an IAi of 95% was observed and during the flood 60%. In addition, B. hilarii proved to be an expert in feeding on E. fusca during the flood, being a generalist during periods of flood, ebb and drought. At the second article, the results show that the diet of B. hilarii is based on corn and soy, in the stretches of the Paraguai/Porto Estrela and Sepotuba rivers, in the TSE, the diet consists of insects, dissolved material and plant debris. Thus, we conclude that the hydrological periods provide a marked diversification in the supply of items food. However, due to the monodominance of E. fusca in the TSE, there was a greater availability of this item in your diet. In the second article, B. hilarii can be concluded that B. hilarii shows itself as an opportunist-specialist, which means that, in the presence of barley, has a preference for this item, which causes a disruption in their trophic relationship.
