Foam separation principle and ammonia nitrogen removing theor of the protein skimmer was 3 - 1 described. A protein skimmer w ith a discharge of 50 m h was designed. The skimmer was used in a recirculation s stem, and relative water qualit parameters: protein, ammonia nitrogen, nitrite, nitrate, organic nitrogen, suspended solid, dissolved ox gen, were tested. The results showed that the egesta of the fish reared and the feedstuff residual could be removed efficientl . The removal efficienc of ammonia nitrogen and protein in the
