Abstract :
Abstract Aquaculture is the fastest growing animal food production sector worldwide and is becoming the main source of aquatic animal foodstuff for human consumption. The intensification of production is an alternative for the needed development in aquaculture that use of more inputs, especially feed per unit area leading to an increase in waste generation from the production systems and resulted strongly criticized for environmental impacts. The total nutrients supplied to production ponds, only 30% are converted into product, while the rest as sediment or sludge is usually discharged into the environment. The impact of waste products from aquaculture has increased public concern and threatens the sustainability of aquaculture practices. Therefore, there is a need to develop culture systems that will increase fish production with efficient waste management in order to limit environmental degradation resulting from aquaculture wastes and ensure its sustainability. This paper reviewed various aspects of waste production from aquaculture and methods of management in different culture systems.
