Aquaponics is a closed-loop system in which the waste water produced from a tank of fish is used as fertiliser to feed a bed of vegetation. In turn, the plant life filters the water through its roots and the cleaned water is returned to the fish tank for reuse. Aquaponics is a form of integrated food production system in which the wastes from one production compartment are used as inputs for others.

FAO and NACA have signed an agreement to convene a global conference on aquaculture in 2020. This will be the fourth conference in a series that began at the dawn of the industry in Kyoto, 1976. Aquaculture 2020 will be held late in the year in China. Arrangements, programme and partner details will be announced via the NACA website in due course.

Marine aquaculture of high value species such as fish is generally reliant on external food supplies and has a negative impact on water quality, generating high organic and nutrient loadings. Integrated multi-trophic aquaculture offers a solution to reduce environmental impact of farming systems, culturing complimentary species that can recycle nutrients and reduce nutrient pollution while generating additional products for sale. This article looks at species selection and integration of trophic levels in system design.

Aquaculture has seen spectacular growth in recent years, and Aqua 2018 celebrated aquaculture’s role as one of the most important food industries worldwide. Held 25-29 August in Montpellier, France, Aqua 2018 brought together scientists, practitioners, students, industry and civil society to highlight the latest global developments in aquaculture research and innovation.

Asian Aquaculture 2018 is dedicated to the sustained progress of aquaculture in the Asian region. The conference will provide a better understanding the systems practiced, highlighting regional needs and constraints within the global context of sustainable intensification of aquaculture. The conference is organised by and will be held at the Asian Institute of Technology, Thailand. Abstract submission and early bird registration is available until 30 September. Please visit the conference website for further information.

Integrated multi-trophic aquaculture is a flexible concept, on which many variations can be developed and should not be viewed as confined to open-water, marine systems. Freshwater integrated multi-trophic aquaculture, perhaps better known as aquaponics, applies the same principles as those used in marine integrated multi-trophic systems. In particular, using plants to reduce phosphorus (and other nutrient) levels in effluents can help farmers meet water quality guidelines and prevent eutrophication in the environment.
