This experiment using chicken and pig manure, respectively, for the farming of different sizes of filter-feeding and omnivorous fishes showed that 1 kg of filter-feeding and omnivorous fishes can be produced by using 16.7 kg of chicken manure or 27 kg of pig manure. Chicken manure is especially suitable for the growth of common carp, silver carp and bighead carp with body weight between 50 and 350 g, while pig manure is more suitable for the growth of Carassius cuvieri. Delta C analysis was used to prove the close relationship between the feeding habits of silver carp, bighead carp, common carp and C. cuvieri and the food base provided by chicken manure directly or indirectly. The study also analyzed the nutrient content of fish flesh in three ponds-chicken-manured, pig-manured and feed-pellets ponds.
