Nanotechnology: A Novel Tool for Aquaculture Feed Development

Aquaculture is emerging as the fastest-growing sector in the world and contributes the best quality food for human consumption as a protein source. It has the immense capability to meet the food demand of the rising population all over the globe. But due to various activities, the quality of fish is degrading, affecting the overall consumption of fish and its demand in the market. The anthropogenic activity causes the depletion of water quality by increasing the unnecessary nutrient load in the water, which leads to various diseases in the water body. Recently, it has been observed that the use of nanotechnology can solve these modern problems in the aquaculture sector. It is emerging as an innovative tool for solving problems in the fields of aquatic health management, hatchery or breeding purposes, genetics and breeding, wastewater management, and so on. Nanotechnology is applied for the advancement of fish nutrition and feed development, which are prominent in aquaculture. Through various research, it has been proved that nanoparticles help to improve feed quality by enhancing the availability of micronutrients. It has been noticed that nanoparticles improve the growth, feed conversion ratio, percentage weight gain, and immune response of aquatic organisms. The application of nanotechnology in the aquaculture sector still requires deep research work. It has some negative impacts, but they can be resolved by researching the implications of green nanoparticles. The present book chapter aimed to provide a deep focus on the innovative and adaptable application of nanoparticles in aquaculture feed development, along with its various future perspectives.
