Two feeding experiments were conducted to determine the effect of supplemental tricalcium phosphate on zinc (Zn) and manganese (Mn) availability to common carp, using semipurified diet. The growth was lowest in fish fed the diet without supplemental Zn or Mn, and was improved by supplementation of Zn and Mn irrespective of dietary tricalcium phosphate level. However, supplement of tricalcium phosphate to the diet having insufficient amount of Mn induced higher incidence of short body dwarfism. Dietary tricalcium phosphate decreased Zn and Mn absorption, leading to reduced levels of Zn and Mn in vertebrae. Thus, tricalcium phosphate in diet was found to be one of the inhibitors against Zn and Mn bioavailability to common carp. Zn and Mn requirements of common carp were reconfirmed to be 15-30 and 13-15μg/g, respectively.
