The diversity of the aquatic organisms in Korean, especially
in aquaculture species is under threat as many culture species have been
imported from foreign countries and some useful fisheries resources have been
continually reduced. Unexpected hybridization between species, making different
ecosystem owing to the combinations of new species etc. can lead to the disappearance
or some aquatic species of reduction of genetic diversity.
Accordingly, it is critically important to identify between different
species with similar morphological characteristics, distinguish between populations
for preservation of species diversity and improvement of species quality
with diverse genetic traits.
The goals and the establishments carried out until now in this
field are as follows:
1. Development of useful marker for identification and
variation analysis between species or populations
2. Evaluation of genetic variations and population structure
analysis of Korean aquaculture species and useful fisheries resources
3. Preservation of gene materials and management of obtained
database
• Isozyme analysis
