The requirement to focus on waste management rests both on regulations and on a responsible approach to operations.
The treatment of wastewater and sludge should seek to minimise the environmental impact of aquaculture to preserve the value of the filtered and treated waste for further use in other agricultural applications. When treated correctly the dried sludge from aquaculture is a rich source of nitrogen and phosphorus.
A focus on waste management can also provide operating benefits. Analysis of waste output can assist in optimising feed management and improving operating procedures.
