Upland aquaculture connotes location of the
fi sh production enterprise in mountainous rolling
areas where water is abundant for the culture of
cold tolerant freshwater fi sh species. Because of
limited space the culture systems basically consist
of dug-out pond, fi sh terraces, small cages and fi sh
condo. The technology is basically the same with
traditional culture systems in the lowland. The
only differences are lower water temperature and
smaller area utilized, hence cold tolerant species
are used, stocking densities higher, feeding
regiment adjusted and the culture period is longer.
