Overview
We evaluate genetic diversity of wild captive broodstock and the artificial seed populations of Ezo-awabi abalone and Japanese sea cucumber using DNA markers.

Overview of the Observation

Results and Future Plan
Significant genetic differentiation was detected among wild captive broodstocks of Ezo-awabi abalone using 10 microsatellite loci and 1303 nucleotide of the mitochondrial DNA genes, suggesting that gene flow is restricted among wild populations along the Sanriku Coast and we have to pay management and/or conservation efforts to the local populations.
