    摘要: Raising ornament fishes in Taiwan is geajng popular. The maintenance of good water quality is very critical in successfully raising the ornament fishes. However, the contamination of water by fish feed seems to be unavoidable problem. The fish feed has more or less polluted the water before they are consumed by fishes or a certain proportion of the fish feed is completely wasted and pollutes the water severely. Therefore, it is the goal of this study to reduce the contamination by fish feed to maintain the water quality.The film coating of the fish feed is used as a means to reduce water contamination by decreasing the erosion of fish feed. Several polymers were screened for their effect in reducing the water turbidity. Chitosan was chosen because of its best effect in decreasing water turbidity. Besides, it is also a natural material from shell. Its floatability, immediate toxicity and coating process by automatic film-coating machine were also evaluated.It was concluded that the coating of fish feed with chitosan can decrease the turbidity of water, and the automatic film-coating machine can be used without damaging the hardness and friability of the fish feed.
