In order to test the practical usefulness of the prober LZF-I we conducted population investigation, paternity determination, tissue stability and applicable extent in fish and obtained following results. The probability of chance association between random individuals was 9.23×10-16,and this indicates that the LZF-I fingerprints are completely individualspecific The paternity probability was 0.999962, and it showed that the inheritance of alleles is in accord with the Mendelian Law. The LZF-I oligonucleotide fingerprinting probe was stable.It was very effective in detecting both individual and species specificities of fish.
