Abstract

|
The author established a PCR-based genetic platform to examine the hierarchical polar dendrogram of Euclidean genetic distances of one tailfin anchovy population, especially for Coilia nasus, which was further associated with other fish population, by connecting with specifically designed oligonucleotide primer sets. Five oligonucleotide primers were used to generate a total of 260 and 211 scorable fragments in Coilia populations I and II, respectively. The DNA fragments ranged from greater than (approximately) 100 to more than 2,000 bp. The average bandsharing values (BS) of individuals from the anchovy population I (0.693) displayed higher values than individuals from population II (0.675). The genetic distance between individuals established the existence of a close relationship in group II. Comparatively, individuals of one anchovy population were fairly related to other fish populations, as shown in the polar hierarchical dendrogram of Euclidean genetic distances. The noteworthy genetic distance determined between two Coilia nasus populations demonstrates that this PCR technique can be applied as one of the several devices for individuals and/or population biological DNA researches undertaken for safeguarding species and for production of anchovies in the littoral area of Korea.
