Abstract/Description: | The climate change is worsening the problems of arsenic poisoning in aquatic ecosystem in India and other parts of the world. The arsenic poisoning mainly spread through groundwater and other means. The cultivated fish are prime contamination of arsenic poisoning and subsequently affected on consumer. However, we designed an experiment with consideration of above points. An experiment was carried out to evaluate efficacy of selenium nanoparticles (Se-NPs) and riboflavin (RF) for reducing the impact of multiple stresses (arsenic and temperature) in term of growth performance, anti-oxidative status and immunomodulation in Pangasianodon hypophthalmus. Se-NPs was synthesized through fish gills using green synthesis approaches. The four experimental diets as control diet (Se-NPs- 0 mg/kg and RF-0 mg/kg diet) and three supplemented diets as Se-NPs- 0.5 mg/kg diet with different inclusion level of RF-5, 10 and 15 mg/kg diet were formulated for P. hypophthalmus fed for 90 days. The total eight treatments were designed in triplicate form with distributed eighteen (18) fish in each tank as per completely randomized designed. The fishes were treated in arsenic (1/10th of LC50, 2.68 mg/L) and high temperature in stressors group while no stresses has been treated in control group fish. Supplementation with Se-NPs and RF diets were significantly (p<0.01) enhanced growth performance (weight gain %, FER, PER and SGR), anti-oxidative status and Immunological status as total protein, albumin, globulin, A:G ratio, NBT, total immunoglobulin, myeloperoxidase in fish. The stressor biomarkers as lipid peroxidation, acetylcholine esterase, vitamin C, blood glucose, heat shock protein 70, and cortisol were significantly reduced (p<0.01) with supplementation of Se-NPs and RF. the thermal tolerance was also evaluated by determination of the following parameters: critical thermal minimum (CTMin), lethal thermal minimum (LTMin), critical thermal maximum (CTMax), and lethal thermal maximum (LTMax). At the end of the experimental, the fishes were treated with pathogenic bacteria and observed cumulative mortality and relative percentage survival for a week. The arsenic bioaccumulation in different fish tissue and experimental water was also determined and found that supplementation of dietary Se-NPs and RF was significantly reduced the arsenic concentration in fish tissues including muscle tissue. However, based on present study, it is concluded that combinatorial mixture of Se-NPs and RF has synergistic effect and important role in alleviation of multiple stresses in P. hypophthalmus. |
