Economics of aquaculture feeding practices in selected asian countries FAO Fisheries technical paper Series, Vol. 505

This technical paper provides an analysis of the economic implications of, and the reasons for, adopting various feeding practices for different fish species and aquaculture systems in Asia. It comprises case studies in six Asian countries (Bangladesh, China, India, the Philippines, Thailand and Viet Nam) and an overall synthesis ending with conclusions and recommendations. The systems studied include extensive/traditional, semi-intensive and intensive farms for a number of different species including sutchi and pangasiid catfishes (Bangladesh and Viet Nam), hybrid catfish (Thailand), carp polyculture (India and China), prawn and milkfish polyculture (the Philippines). The work identifies the principal input costs and assesses the economic rates of return (gross and net margins), returns to labour, land and capital, gross and net total factor productivity, and break-even prices and production.
