    Stringent environmental restrictions to minimize pollution from hatcheries and land-based aquaculture facilities in northern European countries have sparked the rapid technological development, investment and innovation in recirculation systems in many parts of the world. In general, aquaculture production affects the environment, but state-of-the-art recirculation methods reduce this effect considerably compared to traditional ways of farming fish. Recirculation systems thereby offer two immediate advantages: cost effectiveness and reduced environmental impact. Recirculation also secures a higher and more stable aquaculture production with less diseases and better ways to control the hatchery parameters that influence fish growth in aquaculture production systems This development is welcome and fully in line with the FAO Code of Conduct for Responsible Fisheries. This guide focuses on the techniques for the conversion from traditional farming methods to recirculated aquaculture and advises the fish farmers on the pitfalls to be avoided along the way. Key features of the guide are: assists farmers to convert to recirculation aquaculture;
  • introduces the technology and the methods of management;
  • advises on good practise shifting to recirculation aquaculture;
  • specifies running a recirculation system, staff education and training;
  • provides case stories from different recirculation projects.

    Guidelines on Environmental Monitoring for Cage Aquaculture within the Kingdom of Saudi Arabia 2017
    Also available in:
    No results found.

    This document has been prepared based on sound scientific principles and international approaches to monitoring cage aquaculture facilities. In general this is a guide to help support good monitoring practice, with details on what to monitor, parameters to be collected, how data is collected, appropriate ways to process the data and what to do with it once the survey is complete and results available. Such monitoring activity will ensure that cage farms use practices that minimize environmental impacts for the long term sustainability of cage aquaculture within the Kingdom of Saudi Arabia. In this sense the document is for fish farmers and their consultants to ensure a unified process of monitoring using standardized procedures, but is more generally applicable for all stakeholders.

    A Manual for Operating a Small-scale Recirculation Fresh water Prawn Hatchery - BOBP/MAG/13 1993
    Also available in:

    in Potiya, near Chittagong, Bangladesh, is written for those interested is establishing a small-scale inland freshwater prawn hatchery using the clear water method. It is assumed that the reader has some basic knowledge of aquatic biology, but is not necessarily a degree holder in the subject. The method described is based on the use of brine obtained from salt pans. The brine is diluted with well or surface water to make up the rearing water. Such technology is widely used in commercial hatcher ies in Thailand. As rifle is not always available, a simple biofilter, for recirculation of the water, is incorporated in the tank design. The biofilter greatly reduces, or eliminates, the need for water changes during the rearing cycle. The hatchery system described consists of larvae rearing tanks, mixing and brine storage tanks, Artemia incubators and supporting mechanical equipment. Recirculation systems are becoming increasingly popular and have now been shown to give consistent product ion of quality post-larvae. All the necessary details for setting up such a simple system are included in this manual, which is also profusely illustrated to make what is described in the text clearer.
