“…Similar results were observed in Nile tilapia and grass shrimp ( Penaeus monodon ) [ 64 , 66 ]. The RB in serum of red swamp crayfish ( Procambarus clarkii ) and PA in serum of hybrid sorubim catfish ( Pseudoplatystoma reticulatum × P. corruscans ) were significantly decreased after a high level of dietary AA supplementation (321.38 mg/kg and 850 mg/kg, respectively) [ 67 , 68 ]. However, no significant decline in THC, RB and PA in the hemolymph of abalone was observed in the treatment with high levels of dietary AA supplementation (4821.17 mg/kg).…”

The present study was conducted to investigate the roles of ascorbic acid (AA) in immune response, anti-oxidation and apoptosis in abalone (Haliotis discus hannai Ino). Seven semi-purified diets with graded levels of AA (0, 50, 100, 200, 500, 1000 and 5000 mg/kg) were fed to abalone (initial weight: 12.01 ± 0.001 g, initial shell length: 48.44 ± 0.069 mm) for 100 days. The survival, weight gain rate and daily increment in shell length were not affected by dietary AA. The AA content in the gill, muscle and digestive glands of abalone was significantly increased by dietary AA. In terms of immunity, dietary AA significantly improved the total hemocyte count, respiratory burst and phagocytic activity in hemolymph, and lysozyme activity in cell-free hemolymph (CFH). In the digestive gland, the TLR-MyD88-dependent and TLR-MyD88-independent signaling pathways were suppressed by dietary AA supplementation. The mRNA levels of β-defensin and arginase-I in the digestive gland were significantly increased by dietary AA. In the gill, only the TLR-MyD88-dependent signaling pathway was depressed by dietary AA to reduce inflammation in abalone. The level of mytimacin 6 in the gill was significantly upregulated by dietary AA. After Vibrio parahaemolyticus infection, the TLR signaling pathway in the digestive gland was suppressed by dietary AA, which reduced inflammation in the abalone. In terms of anti-oxidation, superoxide dismutase, glutathione peroxidase and catalase activities, as well as total anti-oxidative capacity and reduced glutathione content in CFH, were all significantly upregulated. The malondialdehyde content was significantly downregulated by dietary AA. The anti-oxidative capacity was improved by triggering the Keap1-Nrf2 pathway in abalone. In terms of apoptosis, dietary AA could enhance the anti-apoptosis ability via the JNK-Bcl-2/Bax signaling cascade in abalone. To conclude, dietary AA was involved in regulating immunity, anti-oxidation and apoptosis in abalone.

“…Subtle differences may occur permanently, originating from phylogenetic evolution, or temporarily, produced by individual occurrences (Olsson, 2011; Wilson & Castro, 2011). In the present study, we used juveniles specimens of each species with recognized differences in feeding habits, which are commonly employed as models for understanding responses of the digestive system to the constituents of the diet and weight gain (do Nascimento Veiga et al, 2020; Hassaan et al, 2021; Honorato et al, 2010; Laice et al, 2021; Rodrigues et al, 2018; Zanuzzo et al, 2017).…”

Technological advances in genetic improvement, management, health and nutrition have allowed aquaculture activities to attain high levels regarding animal protein, production, and commercialization.The annual growth of this sector and the nutritional quality of meat are factors that make fish increasingly desirable for consumers. Brazil has emerged as a promising global supplier of aquaculture products due to the growing number of high-tech farms and productivity, particularly in the provision of native fish species (Valentin et al., 2021).Several species of fish play an important role in the economies of many countries worldwide. Many of these species are native and regionally adapted but are raised on fish farms and subjected to adaptive conditioning techniques because of their commercial value.In recent years, global production has experienced substantial advances in productivity methods for human consumption of farmed fish (FAO, 2020). Commercialization success is fundamentally based on dietary strategies for growth and weight gain from several formulated and commercially available fish feeds (Li & Robinson, 2015).However, these artificial feed formulations mainly target protein

“…Em Oreochromis niloticus as dietas suplementadas com vitamina C aliviaram todos os sinais toxicológicos induzidos pela água poluída, através do mecanismo de defesa antioxidante e do sistema de imunidade nos tecidos contra toxicidade imidacloprido (Mahamoud et al, 2020). Rodrigues et al (2018), avaliando o efeito dos níveis classificados de ácido ascórbico dietético (AA) (12.47; 20,27; 115,44; 475,50; 737,72 e 850,70 mg kg −1 ) sobre crescimento, hematologia, morfometria intestinal e atividade de fagócitos do peixe híbrido Pseudoplatystoma × Pseudoplatystoma corruscans verificaram que não houve nenhum efeito de AA dietético em leucócito e trombócito e na atividade dos fagócitos e índice de fagócitos, e que a inclusão de AA na alimentação pode aumentar a integridade da mucosa intestinal e estimular eritropoiese em surubim.…”

A utilização de imunoestimulantes em peixes é um método preventivo para combater infecções que frequentemente acometem os animais no ambiente produtivo, sendo uma alternativa biológica com grande potencial para minimizar o uso excessivo de antibióticos. Na aquicultura, os imunomoduladores são divididos em dois grupos, os imunonutrientes (vitaminas, minerais e aminoácidos) e os imunoestimulantes não nutricionais (óleos essenciais, extratos de plantas, fitoterápicos, prebióticos, probióticos e simbióticos), sendo estes últimos, muito estudados atualmente. Ambas alternativas objetivam maximizar o desempenho, reduzir o estresse, melhorar a saúde do trato gastrointestinal e, consequentemente, a imunidade e resistência às doenças dos peixes. Assim, com a presente revisão de literatura os objetivos são abordar os diferentes imunomoduladores utilizados na piscicultura, dando ênfase ao mecanismo de ação no organismo e níveis de inclusão, bem como ressaltar resultados de estudos realizados com diferentes espécies produzidas em sistema intensivo em larga escala.
