Growth performance, hematological and biochemical effects of iron oxide nanoparticles in Labeo rohita

In aquaculture farming, iron deficiency in fish causes anemia and also causes improper growth. Biologically synthesized nanoparticles are widely used in micro-nutrient delivery in aquaculture as they are eco-friendly, and non-toxic to the environment. Iron oxide nanoparticles can be the alternative supplement to overcome iron deficiency. Therefore, the primary aim of this study was to determine the effect of Amaranthus tricolor mediated iron nanoparticles in the physiological, hematological, biochemical parameters of the Indian major carp Labeo rohita. In the present study characterization of the iron nanoparticles were done. Iron oxide nanoparticles were added to the experimental basal diets at various concentrations. Positive and negative controls were also taken. Feeding experiment showed that iron oxide nanoparticles incorporated diet showed positive result towards the survival, growth and biochemical compositions in Labeo rohita. The values of hemoglobin and erythrocyte count show a significant increase among the different concentration of diet. Fish fed with iron oxide nanoparticle supplemented diet produced a better performance in the biochemical compositions. The results from the study prove that the iron nanoparticles supplemented diet can improve the physiological, biochemical and hematological activities in Labeo rohita. Thus it is inferred that the iron oxide nanoparticles possess the capabilities of being the alternative source to rectify the iron deficiency and retarded growth related problems in Labeo rohita.
