Research Point Map & Track Chart Map & Point List
Results and Future PlanGenetic diversity of Sebastolobus macrochir from both off Tohoku and off Abashiri was very high. The haplotype network revealed that these populations have no genetic divergence. The otoliths from the samples will be investigated to know their year classes.
