Fish yield of the chicken-manured pond was the highest, followed by that of the duck-manured pond, the pig-manured pond and the cow-manured pond. The factors which affected the fish yield were the inorganic nitrogen, phosphorus, and the biomass of zooplankton and phytoplankton.p. 5FAOEffects of different animal manures on the ecological factors and fish yield in fish pondsEffects of different animal manures on the ecological factors and fish yield in fish pondsNetwork of Aquaculture Centres in AsiaNetwork of Aquaculture Centres in AsiaProject
