Abstract: The classical working principle of aquaponics is to provide nutrient-rich aquacultural water to a hydroponic plant culture unit, which in turn depurates the water that is returned to the aquaculture tanks. A known drawback is that a compromise away from optimal growing conditions for plants and fish must be achieved to produce both crops and fish in the same environmental conditions. The objective of this study was to develop a theoretical concept of a decoupled aquaponic system (DAPS), and predict water, nutrient (N and P), fish, sludge, and plant levels. This has been approached by developing a dynamic aquaponic system model, using inputs from data found in literature covering the fields of aquaculture, hydroponics, and sludge treatment. The outputs from the model showed the dependency of aquacultural water quality on the hydroponic evapotranspiration rate. This result can be explained by the fact that DAPS is based on one-way flows. These one-way flows results in accumulations of remineralized nutrients in the hydroponic component ensuring optimal conditions for the plants. The study also suggests to size the cultivation area based on P availability in the hydroponic component as P is an exhaustible resource and has been identified one of the main limiting factors for plant growth.
The EU Aquaponics Hub is looking for a PhD student or early career postdoctoral researcher to assist in the development of an interactive not-for-profit computer game. The researcher will be hosted by the Faculty of Civil and Environmental Engineering, University of Iceland, and a maximum grant of EUR 2500 will be awarded as a contribution towards the cost of travel, board and lodging.

The 5th Management Committee and Working Group meetings of COST Action FA1305 will take place at the University of Ljubljana, Slovenia, from 22 to 24 March 2016.
On 22 March we have organised an international line-up of guest speakers and members of the Action who will be presenting overviews of the state-of-the-art of aquaponics in different parts of the world, and the results of their latest research.
The ‘Aquaponics Research Matters’ conference will be open to the public, and tickets are free of charge. Attendees must register for a ticket using Eventbrite.
