Nanotechnology is envisioned as a solution for preventing and monitoring diseases and infections. A few significant applications of nanotechnology for improving fish health are,
• Development of antibacterial or antifungal surfaces using porous nanostructures
• Use of nano sensors in freshwater aquaculture for bacterial identification in waterways.
• Administration of veterinary items and fish medicines via fish meals
• Nano-trace element usage involves utilizing trace elements in nanoscale forms, which can be up to 100 times more effective compared to standard inorganic trace element usage.
• This enhanced efficacy is attributed to the ability of nano-sized particles to directly penetrate animal organs, facilitating better absorption and utilization of trace elements for improved physiological functions
Antibacterial Drugs
• Nanotechnology has enabled new research methodologies to develop antibacterial drugs
• Nanotechnology-based drug delivery systems can now be used to treat chronic intracellular infections in both humans and animals.
• Existing research has established the feasibility of introducing nano shells and nanotubes into animal systems to kill specific cells.
• Drugs have been delivered into cells using nanoparticles with few adverse effects
• Through co-enzymatic systems, the creation of nanoparticles from metals involves a variety of biological processes.
• Novel antimicrobial medicines are needed due to an increase in bacterial illness outbreaks in the aquaculture business and the development of bacterial resistance.
• Silver nanoparticles are one of the most effective metallic nanoparticles with antibacterial activity against a variety of bacteria and fish pathogens
• Researchers tested the antibacterial properties of ZnO nanoparticles on the pathogenic V. harveyi bacteria and discovered that nanoparticles had better bactericidal effects than bulk ZnO
• Furthermore, biological zinc nanoparticles (BIO ZnONPs) were found to have good antibacterial action against harmful fish pathogens in Nile tilapia (Oreochromis niloticus) After activation by light, TiO2-NPs doped with magnetic Fe3O4-NPs displayed a bactericidal effect
• Because fish infections link to nanoparticles, which can then be easily removed from water using a magnet, these particles can be utilized to treat water .
