The genetic variability of the landlocked population of Ayu, <I>Plecoglossus altivelis</I> in the Nomura dam was estimated using DNA fingerprinting and allozyme markers. Based on the allele frequencies of the <I>GPI-1 100</I> and <I>MPI 100</I> markers, it is suggested that the Nomura's population originated from the amphidromous form. Using 22 allozyme markers, the proportion of polymorphic loci and the average heterozygosity (Ho) were estimated as 0.182 and 0.061, respectively, suggesting that the genetic variability in the Nomura's population has been maintained at a level similar to the native amphidromous populations. On the other hand, the genetic similarity (as Band Sharing Index, BSI) obtained by DNA fingerprinting was 0.586 with YNZ22 probe, and 0.472 with 33.15 probe. These values were higher than those of the native amphidromous populations, suggesting that the effective population size (<I>Ne</I>) of the Nomura's population is decreasing.
