Effect of dietary supplement (cevas) on the chemical composition of wild fish Brycon falcatus Müller & Troschel, 1844 in the Teles Pires river basin Biological Sciences

 In the Teles Pires River watershed, one of the most common techniques currently used by fishermen to catch fish is to provide a food supplement commonly known as “cevas”. The purpose of this study was to compare the chemical composition of fillets from Brycon falcatus that were caught in both the presence and absence of cevas. The fish were sampled monthly and captured in the following conditions: the Tapaiúna River without cevas, the Teles Pires River with one ceva/100 m, the Celeste River with one ceva/500 m, the Verde River with one ceva/1000 m and the Cristalino River (control area). Subsequent to capture, the fish were euthanized and preserved on ice to determine their water, ash, crude protein and fat contents. Fillets of fish from the control area...

Heavy metal bioaccumulation of the characiform Brycon falcatus Muller & Troschel, 1844 in the Teles Pires basin, Southern Amazon Biological Sciences
Matos, Liliane Stedile de; Silva, Daniela Rocha da; Silva, João Otavio Santos; Andrade, Ricardo Lopes Tortorela; Carvalho, Lucélia Nobre.
The Teles Pires River basin is located in an area of the Southern Amazon where discharge of tannery effluents and intense agricultural activity occurs. These activities increase the risk of contamination by runoff and leaching of pesticides and heavy metals. This study presents the concentration and bioaccumulation of heavy metals copper (Cu) and total chromium (Cr) in matrinxã (Brycon falcatus), a species of fish highly consumed in the region. Liver and muscle tissue was analyzed from 41 samples of B. falcatus collected during the dry season in 2013 from the Teles Pires River basin. Considering that bioaccumulation is the progressive increase in the amount of a substance in an organism or part of an organism, copper bioaccumulation in liver samples from...
