Description

Abstract: Research at the Asian Institute of Technology (AIT) in small-scale farmer aquaculture systems began in 1979 with a survey of fish farms in Pathumthani Province, Central Thailand (Edwards et? al., 1983). A major conclusion was that farmers were constrained by a shortage of suitable fertilizers and feed inputs. Large- scale commercial farms in the Province were integrated with feedlot livestock and/or used waste food from canteens or agro-industrial factories as fish feed. As the latter are seldom available in rural areas, it was recommended that small-scale farmers culture fish in integrated systems with feedlot livestock.
