“…Animal Sciences, v. 45, e61884, 2023 In addition, it is possible to attribute the higher levels of minerals (macro and micro minerals) in the musculature of these species to the increased diversity of food found in the flooded forests during the flood periods (Mortillaro et al, 2015;Garcez, Souza, Frutuoso, & Freitas, 2017;Silva, Arantes, Freitas, Petrere, and Ribeiro, 2020;Hurd, Baccaro, Pouilly, & Freitas, 2021). During the flood, pacu, matrinxã, curimatã, sardinha, and jaraqui are often found in flooded forests feeding mainly on fruits, seeds, insects, vegetable matter, and debris (Costa & Freitas, 2013;Mortillaro et al, 2015;Silva et al, 2020); which may explain their high Fe, Cu, Ca, and Mn values during flooding. For piramutaba, the high levels of Na and K observed during the flood season may be related to the natural history of the species, which spend a large part of their life cycle in the Amazon River estuary, in brackish waters, migrating upstream from May to October (full to low) to reproduce in the high Amazon.…”
