In order to investigate the optimum level of dietary equiponderance compound of monopotassium phosphate and monosodium phosphate (MPP+MSP) levels on the growth, feed conversion, vertebral deformity and body composition of juvenile tiger puffer, Takifugu rubripes, the fish were fed for 41 days with practical diets supplemented with 0 - 2% MPP+MSP. Dietary supplementation of 1.0% or more MPP+MSP improved considerably the growth, feed efficiency and vertebral deformity. In addition, the content of phosphorus and calcium in the whole body of fish almost became constant by adding MPP+MSP of 1.5% or more. These results indicate that the dietary supplementation of MPP+MSP can improve the growth and feed performance of the fish, and that its optimum level is likely to be 1.5%. Moreover, the amount of phosphorus fractionated with deionized water is 0.64%, it was similar to 0.6 - 0.7% that the amount of the requirement of carp.
