Phosphorus Waste Production in Fish Farming a Potential for Reuse in Integrated Aquaculture Agriculture

Abstract The development of aquaculture in recent years to become the fastest growing food production in the world is accompanied by a secondary effect on the environment, since considerable quantities of waste can be produced and discharged into the environment, as these phosphorus-rich effluents, over time, can contribute to eutrophication phenomena in the aquatic environment. This pollutant is essentially of food origin and is a necessary macro-mineral for fish. However, current scientific and technical means are far from offering the solution to the environmental problems posed by aquaculture development. However, this effluent is a compound that is necessary for the soil as a fertiliser and has great potential for reuse. In this context, aquaculture systems must therefore be well managed to ensure the environmental sustainability of the sector by exploiting these phosphorus-rich discharges in the system of integrating aquaculture with agriculture. The integration of agricultural and aquaculture production systems is seen as a sustainable alternative and as a way to rationalise the use of water and fertilisers. However, for the optimisation of this integrated system to be justifiable in terms of the exploitation of phosphorus from aquaculture effluents, it is necessary to take ownership of the processes involved in the presence of food-borne phosphorus in these effluents and the possibility of its advantageous use both in aquaponics and in agricultural irrigation, the aim of which is to increase the efficiency and sustainability of both aquaculture and agriculture.
