“…The histopathological alterations observed in P. mesopotamicus indicate the toxic effects of AFB1 and have been reported in other fish species as well (Mahfouz and Sherif, 2015;Anater et al, 2020a). One of the liver disorders that most commonly occur after AFB1 intoxication is increased vascularization, which results in increased blood flow and catabolic excretion (Venturini et al, 2019). The occurrence of focal necrosis may be the result of increased ROS production due to AFB1 action in cellular mitochondria.…”

In this study, we evaluated the effect of aflatoxin B1 (AFB1) in pacus (Piaractus mesopotam- icus) that were fed diets containing 0.0; 25.0; 50.0; 100.0; 200.0, and 400.0 µg kg−1 of AFB1 for 10 days. Furthermore, also was evaluated the effect of an adsorbent (0.2%) supplemented in fish diets containing 0.0, 25.0, and 400.0 µg kg−1 of AFB1. At the end of each experiment, fish were fasted for 24 h, and the survival rate was measured. Six specimens from each treatment were randomly selected for assays of tissue metabolic indicators in the liver: superoxide dismutase, catalase, alanine aminotransferase, aspar- tate aminotransferase, and albumin and six, for histopathological analysis. Hepatic metabolism showed lesions in fish fed with doses higher than 25.0 µg kg−1 of AFB1. The histopathological results revealed necrosis of the liver. The addition of 0.2% adsorbent promoted the restoration of liver functions in fish fed with diets containing 25.0 µg kg−1 AFB1. The histopathological results demonstrated hepatic tissue with a healthy architecture. In conclusion, AFB1 at a concertation of 25.0 µg kg−1 negatively affects the liver, but the addition of a probiotic-based adsorbent (PBA) in fish diet containing 25.0 µg kg−1 AFB1 cancels the toxic effects of AFB1. Therefore, the use of PBAs in fish diets are recommended.

“…Oxidative stress results from an increase in reactive oxygen species (ROS) (Venturini et al, 2019), which disrupts cellular homeostasis (Elliott et al, 2020). The presence of high hepatic levels of hydroxyl radicals (•OH and O2 −• ) inhibit CAT activity (Modesto and Martinez, 2010).…”

“…O estresse relacionado à intoxicação também pode explicar os resultados sanguíneos encontrados no presente trabalho. Venturini et al,(2018) relatam que o estresse por exposição a agrotóxico aumenta o cortisol e glicose no sangue de matrinxãs (Brycon amazonicus), sendo esses parâmetros os princípais indicadores de estresse em peixes (Barton, 2000).…”

O Piaractus mesopotamicus é um peixe endêmico da bacia dos rios Paraná-Paraguai, apresentado boa adaptação em sistema intensivo de produção. Nesses sistemas, a amônia pode alcançar níveis extremos quando atividades nutricionais e de manejos não são corretas. Neste sentido, o objetivo do presente estudo foi avaliar a capacidade de tolerância de P. mesopotamicus expostos a diferentes concentrações de amônia e seu efeito na glicemia e concentração de amonia plasmática. Foram utilizados 36 exemplares com peso médio de 268 ± 71 g e 20,7 ± 3,08 cm de comprimento padrão, dividios em 12 aquários contendo seis tratamentos e três exemplares por unidade experimental. Os tratamentos foram compostos por concentrações diferentes de NH4Cl nas seguintes doses: 0,0 (controle); 0,1; 0,2; 0,4; 0,6; e 0,8 mg.L-1 durante um período de 96 horas. Análises dos parâmetros de qualidade da água foram realizadas a cada 24 horas, a mortalidade contabilizada com intervalos de no máximo 12 horas e as análises sanguíneas foram realizadas nos animais sobreviventes ao teste. A amônia é tóxica para os pacus a partir de 1,674 mg.L-1de N-NH3, dose em que ocorreu a mortalidade de 50% da população em 66,75 horas e em 100% da população em 92,5 horas. O elevado nível de glicose observado no tratamento 0,4 de NH4Cl pode ser atribuído ao estresse a que esses animais estavam acometidos, pois todos os animais estavam em um mesmo tempo de jejum. Conclui-se que 50% da população de P. mesopotamicus é tolerante até a 1,674 mg.L-1de N-NH3 num período de 66,75 horas.

“…Because of the presence of biologically active substances in plant residues (Neves et al, 2012), the development of products with biological activities, and concomitantly added value to these raw materials (Vanegas-Espinoza et al, 2019), is valuable. The action of antioxidant enzymes in the organism may not fully minimize the damage caused by free radicals produced during metabolic processes or by the organism's exposure to exogenous factors (Venturini et al, 2019). The pitaya plant (Hylocereus polyrhizus) belongs to the Cactaceae family and is a climbing fruitful cactus; its fruit has an intense red pulp and rind derived from pigments known as betalains (Wong and Siow, 2015), which makes it interesting as a source of natural colorings.…”

The experiment was conducted to evaluate the composition of the hydroalcoholic extract of pitaya bark (Hylocereus guatemalensis) and its effects on the diet of male blue Betta splendens concerning the content of digestive enzymes, liver metabolism, and activity antioxidant. The fish were supplemented with hydroalcoholic extract of pitaya bark (HEPB) at the concentrations of 0.24, 0.45, and 0.90 mg kg −1 of feed for 21 days. The inclusion of 0.24 and 0.45 mg kg −1 HEPB promoted the best results of zootechnical performance. The digestive activity showed an increase in alkaline phosphatase activity only when 0.45 mg kg −1 HEPB. The inclusion of 0.45 and 0.90 mg kg −1 HEPB promoted a decrease in hepatic ALT activity. An increase in CAT activity was observed in the skin of fish fed diets with added HEPB. Conclusion addition of HEPB is benefic for performance and have hepatoprotective.
