Aqua cultural production is a major industry in many countries, and it will continue to grow as the demand for fisheries products increases and the supply from natural sources decreases. Good nutrition in animal production systems is essential to economical production of a healthy, high-quality product. In fish farming (aquaculture), nutrition is critical because feed typically represents approximately 50 percent of the variable production cost. Fish nutrition has advanced dramatically in recent years with the development of new, balanced commercial diets that promote optimal fish growth and health. The development of new species-specific diet formulations supports the aquaculture industry as it expands to satisfy increasing demand for affordable, safe, high-quality fish and seafood products. Article provides a general overview of the wide variety of nanomaterials and technologies in fish culture that offer significant promising role for water recovery. | Feeding of different categories of fish, their nutritional requirements and implication of various techniques in fish culture – A review
