Titre Insight into bacterial population in aquaculture systems and its implication Type (up) Article scientifique

Résumé The current onshore aquaculture trend is to develop large scale production of diversified fingerlings and very large units for fish ongrowing. This requires an industrial type of approach including quality assurance and minimization of failures in addition to management of bio-technical and economic aspects. Therefore, all the key biological mechanisms involved in Recirculating Aquaculture Systems (RAS) need to be better understood, especially those determining the development of bacterial populations and their interactions with fish. This review presents new knowledge on bacterial community compositions in various parts of RAS and on bacterial-fish interactions in RAS, which constitute essential tools for system management.

Titre New developments in recirculating aquaculture systems in Europe: A perspective on environmental sustainability Type (up) Article scientifique
Année 2010 Publication Aquacultural Engineering Revue Abrégée
Volume 43 Numéro 3 Pages 83-93
Mots-Clés Intensive systems; Ecological impact; Waste; Water re-use; Denitrification
Résumé The dual objective of sustainable aquaculture, i.e., to produce food while sustaining natural resources is achieved only when production systems with a minimum ecological impact are used. Recirculating aquaculture systems (RASs) provide opportunities to reduce water usage and to improve waste management and nutrient recycling. RAS makes intensive fish production compatible with environmental sustainability. This review aims to summarize the most recent developments within RAS that have contributed to the environmental sustainability of the European aquaculture sector. The review first shows the ongoing expansion of RAS production by species and country in Europe. Life cycle analysis showed that feed, fish production and waste and energy are the principal components explaining the ecological impact of RAS. Ongoing developments in RAS show two trends focusing on: (1) technical improvements within the recirculation loop and (2) recycling of nutrients through integrated farming. Both trends contributed to improvements in the environmental sustainability of RAS. Developments within the recirculation loop that are reviewed are the introduction of denitrification reactors, sludge thickening technologies and the use of ozone. New approached towards integrated systems include the incorporation of wetlands and algal controlled systems in RAS. Finally, the review identifies the key research priorities that will contribute to the future reduction of the ecological impact of RAS. Possible future breakthroughs in the fields of waste production and removal might further enhance the sustainabilty of fish production in RAS. (C) 2010 Elsevier B.V. All rights reserved.
