Abstract
Allele frequencies and genetic variability of six stocks of common carp collected from
Indonesia and three stocks from Japan were evaluated. Twenty-three loci were identified from 11
enzyme and protein systems. Five loci were polymorphic for the Indonesian stocks and eight loci
were polymorphic for the Japanese stocks. PGM, EST and GPI were useful for comparison
between the Indonesian and Japanese stocks as well as stocks from Europe and China. In
general, genetic variability of the stocks from Japan was higher than that of stocks from
Indonesia. The genetic distance between pairs of stocks, based on 23 isozyme and protein loci,
showed distinct genetic differentiation between Japanese and Indonesian stocks. The sources for

the Japanese and Indonesian common carp are discussed in relation to the European and Chinese
common carp.
