environmental deterioration in and around aquaculture facilities. Such negative effects have
become increasingly conspicuous since the commencement of fish farming in the mid 1960s and
its subsequent rapid development during the 1970s and 1980s. Various studies have attempted to
measure the material fluxes in fish farms, to assess the potential environmental impacts, to
determine criteria the optimization of the location of farms and production levels, and to establish
methods for improvement of aquaculture environments. In this review, research conducted during
the last five decades in Japan concerning the flux of feed, environmental impacts of fish farming,
factors controlling the degree of impacts, the upper limit of production and methods for
improvement of environments is reviewed and current concerns for aquaculture environments
discussed.
