New Innovative Technologies for Sustainable Aqua Production

Abstract

A number of health benefits accrue by consuming fish. Aquaculture is one of the fastest-growing food production sectors. Over 500 species of finfish, crustaceans, mollusks, other aquatic animals, and seaweeds are being cultivated in the world. The rapid growth of aquaculture during recent years has raised questions concerning its environmental sustainability. A number of innovative aquaculture technologies like the recirculatory aquaculture system, running-water fish culture, biofloc technology, aquaponics, and cage culture have been developed and applied to fetch enhanced production and mitigate the concerns for environmental management, responsible aquaculture production and fish health. The recirculatory aquaculture system is a new water quality improvement technology through recirculation and bio-treatment of the water in fish production system. Biofloc technology is used to enhance water quality through balancing carbon and nitrogen in the system. Aquaponics is a soilless culture technology, combining hydroponics and aquaculture in a system. The nutrient film technique allows large amount of oxygen at the root zone of the plants along with moisture and nutrition. Cage aquaculture is appropriate to utilize reservoirs and lakes to enhance fish production. These new innovative technologies are very efficient in sustainable aqua-production.
