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.

Invasive apple snails (Pomacea spp.) in Vietnam: Short review; A review of fresh water integrated multi-trophic aquaculture: Catching up on the dream of a blue revolution in India; Pre-pupae (larvae) of black soldier fly - a potential alternate protein source for aquaculture feeds; Penaeid shrimp and giant prawn seed collection from Rupnarayan River in Purba Medinipur, West Bengal, India; NACA Newsletter; First training course on culture-based fisheries held in Nha Trang, Vietnam.

This collection contains video recordings of the lectures from the Regional Training Course on Culture-based Fisheries in Inland Waters, held at Nha Trang University, Vietnam. The objective of the course was to provide participants with the skills to assist local communities to plan and manage culture-based fisheries; a relatively simple and low cost technology that can deliver nutritional and economic benefits to rural communities with few livelihood options. The course was sponsored by the United Nations University Fisheries Training Programme.
